[beagleboard] RE: MotorBridgeCape and Not Working/Seth

[Mala Dies]

Hello,

I have tried to use my MotorBridgeCape from the BBG and SeeedStudio.com. I 
have been unsuccessful so far. I read some forum at SeeedStudio.com but I 
have been unable to understand why something they typed up in 2014 does not 
currently work (04/2016).

Now, here are some photographs to better assist in the idea behind why I 
cannot get my Cape to work on the BBG. Oh and I had to use WinSCP to change 
the file names in the Linux system because when I unzip their .zip file to 
update firmware on the MotorBridgeCape, I get loads of errors.

Here goes it:




and...




and...



Now...

With these three images, hopefully someone out there can offer assistance.

Seth

P.S. If you need any other info, please contact me.

Hello,

I have Angstrom as a primary system for my BBB. I think I may have one of

Nevertheless...I still use it for learning and getting to know hardware and

Can I get Debian on my BBB from Angstrom?

Hello,

I am working out of a book. It is called "30 Beaglebone Black Projects for 
the Evil Genius." The author has a GitHub.com page online 
at https://github.com/ChristopherRush/BB-Evil-Genius. I am on Project16.js 
and Project16.html. I have gotten scores of error codes. I have been 
unsuccessful updating my Bonescript and Socket.io languages on the BBGW.

If there are any people out there working out of this specific book, please 
join in. I can sure use some advice and further understanding.

I know it is me that cannot make the software work with my current 
configuration(s).

Hello...using Win 10 OS has a drawback on unsigned drivers. You have to 
follow these 
instructions: 
http://www.howtogeek.com/167723/how-to-disable-driver-signature-verification-on-64-bit-windows-8.1-so-that-you-can-install-unsigned-drivers/.
 

*After I followed those instructions, my BBB and BBGW worked all over

[beagleboard] RE: The BBBL and BBBW and BBGW and Stuff/Seth

[Mala Dies]

Hello,

I have some boards from the BeagleBoard.org business. I like these boards. 
I use them and I learn with the boards. I just came across the BBBW and 
BBBL. I decided to reach out and get them. Quickly, I was stopped by the 
"Wall of Linux" in the field of WiFi. I realized that I learned how to 
perform specific tasks in Linux but not how to set up WiFi.

Does anyone have any ideas on how I am supposed to set up WiFi? If you know 
and if you are willing to share, this would be superb. And yes, that word 
is superb. I have not used that word in a bit and I needed to use it once 
more.

Seth

P.S. I have been working more with the Motor Bridge Cape and the BBG 
lately. All I can remember from the book by Molloy on setting up WiFi was 
that it does not work. Please send some sort of guidance. I can program 
them and make the boards useful but I would rather set up WiFi, update my 
board with a new .img file, and then spawn from there. Shoot!

[beagleboard] RE: The Arrow BBB and PuTTY/Cloud9

[Mala Dies]

Hello,

Is there a specific kernel and/or Debian Distro that does not work with the 
Arrow BBB? I am asking because I just received a BBB from the Arrow MFG. 
group and the board has not worked so far. I have tried to update the 
image, I have used PuTTY/Cloud9, and I have updated the PuTTY software 
thinking this would be an issue. Although this fixed some of the 
connectivity issues with my other boards, it did not fix the connectivity 
issue with the Arrow BBB. Besides that mess, I ordered a Rev. C and got a 
Rev. A. 

Seth

P.S. I am dealing with the Arrow people now at Arrow.com but just in case 
this is my issue, I need to find a way to make my board work on my system. 
I have downloaded the required software drivers and plugged the sucker in. 
I still cannot advance to the online part to my board. I have been unable 
to even get PuTTY and Cloud9 recognize that my board is plugged in. My 
computer shows the file system but I cannot get it to work for some reason. 
Aw!

I set up a file to make sure my ESSID and Encryption key were used for 
setting up WiFi in a *wpa.conf* file. I reset the networking from intit.d 
and it resets. Then I command the system with *ifup wlan0*. I get a readout

have been unable to configure this port to make it a WiFi port.

I get no RX bytes and no TX bytes back or in rotation.

[beagleboard] Re: connmanctl

[Mala Dies]

Hey Yo,

*connmanctl *is used as the initial command 
from https://01.org/connman/documentation.

Then, you have to type in, while under the command connmanctl, *wifi enable*. 
While still under the connmanctl command, type in *wifi scan* and then type 
*services*. It will show your *wifi_blah, blah, blah, blah, blah_blah, 
blah, blah_managed_psk *Wifi address to type in once you type *agent on* 
and then *connect*. So you would type this under connmanctl:

wifi enable

wifi scan

services

agent on

connect wifi___managed_psk

then...

You will be asked for a password. Enter the password you have for your 
router.

Done! I was taught this earlier today.

Seth

P.S. Enjoy!

[beagleboard] RE: Working with Flask and Apps with Port 81

[Mala Dies]

Hello Again,

Seth here. I am working out of a book and Flask is the subject. 

*from flask import Flask*
*app = Flask(__name__)*

*@app.route("/")*
*def hello():*
*return "Blah, blah, blah!"*

*if __name__ == "__main__":*
*app.run(host='0.0.0.0', port=81, debug=True)*

The above software should run an app online at http://beaglebone.local:81 
and I should get some feedback on my PuTTY command line. 

Issue 1: The sudo python super-Flask.py software runs and does not quit but 
when I arrive via Chrome to my port address, there is nothing but an error 
on the online page stating that this host does not exist.

Issue 2: Should I use another host or port? I have no clue and the people 
from Flask sent me back to the "you people." BBB! Oh and the BBBW!

Seth

P.S. If you have any ideas, hit me up. I sure could use some three-year 
hiatus fixes.

[beagleboard] Re: Working with Flask and Apps with Port 81

[Mala Dies]

Hello...I figured I could do some damage to the software but nope. I just 
changed the 0.0.0.0:81 host:port values and BAM, it worked.

With Flask, use your BBB SSH sign in credentials (IP address) for the host 
and use port 5000. This should work universally with older model books that 
want to use other hosts and ports, e.g. that are outdated or no longer used 
with specific software.

Seth

P.S. Enjoy!

[beagleboard] Hey Yo! I Need It!

[Mala Dies]

Hello,

I was just out there wondering one day what type of Terminals are located 
on the BBBL. So, what type of terminals are located on this thing?

I see there is a battery, LiPo input section and some servo connectors. I 
see a bunch of what look like Grove terminals on this thing. What are they 
actually called? I would like to know so I can find out exactly what I need 
to do to make connections or for me and the purchasing thing in life.

Seth

P.S. Any ideas would be very beneficial, i.e. to me only. I am sure I could 
build something, post a build, and then coordinate but I just, for now, 
need to know the names of these connections/terminals for the BBBL. For 
Dell's sake, I live in Louisiana. Everything is backward here and no one 
has MCUs for selling or any information on this type of stuff unless I am 
dealing with Oil and Gas.

[beagleboard] Re: Can't connect on Wifi

[Mala Dies]

If you are using any of the WiFi boards from Beagleboard.org, use 
https://beagleboard.org/discuss?place=msg%2Fbeagleboard%2FhoK8GCAOwl0%2FCUk5yDpJAgAJ.
 
It is what I found to be helpful. I got this info. from their people that 
provide help on their #beagle channel on Freenode IRC.

P.S. If this is not what you are discussing, please reply. I will try again.

[beagleboard] RE: TMP36 and BoneScript on BBB/Hello

[Mala Dies]

Hello,

I am on P9_40 with my TMP36 temperature sensor. I used the book, "30 
BeagleBone Black Projects." It is lesson number 11. It has some BoneScript 
lessons but I think the book is outdated. Does anyone know of the updates 
and how it pertains to temperature sensors?

Seth

P.S. Here is the software I cannot get to read. I am going to try and set 
it up in Cloud9 instead of on PuTTY and see what happens.

var b = require('bonescript');

var inputPin = "P9_40";

getBeagleTemp();

function getBeagleTemp();
var value = b.analogRead(inputPin);

var millivolts = value * 1800;
var temp_c = ( millivolts - 500)/10;

setTimeout(getBeagleTemp, 1000);

console.log(temp_c);
}

These are the error codes for the older software listed above. If anyone

*function displayTemp(reading) {*
*var millivolts = reading.value * 1800;*

I found this software and changed it a bit. I use P9_39 or P9_40, i.e. 
whichever. I get a read out but it is not what I thought it would be for 
tempF.

Seth

P.S. I got this software from a book, I think. It is either from, 
"Programming the BeagleBone Black," or the software on the updated images, 
e.g. analog2.js. I will research it again.

*Hello...*

I tried this software outside of the Cloud9 IDE. I ran into an error. It 
says that it could not find the module *bonescript. *Directly afterwards, I 
tried to download, via npm, bonescript to see if there were any updates. I 
received a bunch of error codes. I guess I am just going to try the Cloud9 
IDE for now.

Um, if anyone needs to see the bonescript download error codes, let me 
know. Oh and the first error while downloading bonescript was a node issue. 
Bonescript must use an update version of node while what I need is an 
outdated version of node.

Seth

P.S. If anyone can make that software work, let me know. Oh and BBB!

[beagleboard] node --version

[Mala Dies]

Hello,

What version of node should I be running on a BBB?

Seth

P.S. I think because I attempted to download a version of node that 
bonescript does not accept, I am busted. Anyway, please reply!

Okay...I can check on that too. I just thought using the bonescript

Re: [beagleboard] Re: TMP36 and BoneScript on BBB/Hello

[Mala Dies]

Hello Again,

Thank you. I will look into it. I know very little about node.js. I have 
been following some books on the BBB. I just know how to run .js files with 
node. That is about it for now.

Seth

P.S. I have used the ADC from the Adafruit_BBIO a long time ago but I 
stopped once things got odd. I was having trouble calling ADC with success. 
Anyway, thank you and I will check it out.

[beagleboard] RE: The uEnv.txt File and Changing to "Have Full Control"

[Mala Dies]

Hello,

How would I set "uenvcmd" to have full control?

Seth

P.S. I am asking because I set up a PWM script from an Adafruit software 
thing to run a Python program to fade a Diffused LED. I am getting some 
errors. The command line returns a RuntimeError. When I enable all comments 
in the /boot/uEnv.txt file, I get a system that is unresponsive when I 
reboot or shutdown and then boot.

[beagleboard] Re: The uEnv.txt File and Changing to "Have Full Control"

[Mala Dies]

Hello Again,

Maybe some extra input would help. I get RuntimeError: Problem with the 
Cape Manager, when I run:

*import Adafruit_BBIO.PWM as PWM*
*import time*

*red = "P8_13"*
*green = "P8_19"*
*blue = "P9_14"*

*PWM.start(red, 0)*
*PWM.start(blue, 0)*
*PWM.start(green, 0)*

*def fade(colorA, colorB, ignore_color):*
*PWM.set_duty_cycle(ignore_color, 100)*
*for i in range(0, 100):*
*PWM.set_duty_cycle(colorA, i)*
*PWM.set_duty_cycle(colorB, 100-i)*
*time.sleep(0.05)*
*while True:*
*fade(red, green, blue)*
*fade(green, blue, red)*
*fade(blue, red, green)*

I have set *cape_enable=bone_capemgr.enable_partno= *to enable.

Seth

P.S. If you know of what mistake I am making in my setup of the BBB with 
regards to the Cape Manager, please try to explain or I will keep trying 
(as usual). Cool!

[beagleboard] Re: The uEnv.txt File and Changing to "Have Full Control"

[Mala Dies]

Hello,

I found PWM(1A, 2B, 2A) to be well suited for the software on this 
discussion/question in the cape_mgr on my BBB. This is what I mean. I 
installed those PWM pins at cape_enable=bone_capemgr.enable_partno= to make 
it cape_enable=bone_capemgr.enable_partno=PWM1A, i.e. and etc. There is 
only one section listed for me to enable these pins.

I need three PWM pins available to run this software.

Seth

P.S. Any advice will be okay. I am going to try and run *slots* to see if I 
can add some PWM pins.

I get an error when I run slots:

sudo sh -c "echo 'PWM1A' > /sys/devices/platform/bone_capemgr/slots" is 
what I type in to get the new pin configured. My error is as follows: *sh:

Hello,

I am using a BBB/BBBW. I am also trying to establish a connection via 
tightvncserver. I have accomplished this connection but there are some 
complications. I am obviously incorrect somehow. Who knows why? Anyway...


   - 
   
http://www.toptechboy.com/beaglevone-black-rev-c/beaglebone-black-lesson-2-getting-started/#comment-37975.
   - This site gives me some basic background info. on a procedure.
  - I tried it.
   - I keep getting a repetitive screen that establishes itself over and 
   over again without any more commands.
   - I cannot find out how to control my tightvnc viewer either.


Send applause or suggestions. Either/or would be nice.

P.S. For instance, imagine the screen you are viewing right now cascading 
downward so you cannot work on it and it keeps falling. Boo!

[beagleboard] Re: MikroBus Cape quick-start with drivers?

[Mala Dies]

Hello...I tried to get the MikroBus Cape up and running. They had some 
info. on the mikroe.com site for specific clicks but you, as I believe, 
would need the compilers from their site.

Seth

P.S. I tried to get around things but I suck at this game. I kept trying 
and to no avail. If I get any closer, I will post again.

[beagleboard] RE: Um...My Temp in F Degrees is the Same as the C Degrees/Dang!

[Mala Dies]

var b = require('bonescript');

function readTemp() {
b.analogRead('P9_39', displayTemp);
}

function displayTemp(reading) {
var millivolts = reading.value * 1800;
var tempC = (millivolts - 500) / 10;
var tempF = (tempC * 9/5) + 32
console.log("TempC = " + tempC + "\t Temp F = " + tempF);
}

setInterval(readTemp, 10);

Okay...

This is my software from "Programming the BeagleBone Black" in the 
"hardware interfacing" section. I am messing with a TMP36 sensor for analog 
temp. reads.

The issue is this:

I keep getting a similar read for my C and F reads. I should be able to get 
the F read but unfortunately, I get the same as the C read.

Seth


P.S. Try your TMP36 sensor and this software and get back to me. I would 
love to know about the value(s) I am creating and why they are returning 
the listed read(s). Oh and here is a photo. See!

Re: [beagleboard] RE: Um...My Temp in F Degrees is the Same as the C Degrees/Dang!

[Mala Dies]

Hello Rob,

Seth here. I am located in the states. There is a big fault and I am not 
clued in, obviously. How is F == C? I figured that there would be a part to 
the software, the section that displays the difference, that tells me/you 
the C and F reads. 

Seth

P.S. I am in about an 80 degree temp. right now. So, do I need to replace 
"reading.value" with an actual numerical value? I will keep trying.

Mr. Rob,

Why would I use the value 4096.0?

Seth

P.S. I have tried to suit the software to suit my needs and I keep coming 
up empty. I will try this value and I will get back to you.

[beagleboard] RE: ECMA-262/2015

[Mala Dies]

Hello,

If there are any ECMA-262 enthusiasts, let me know. It was done in 2015 and 
holds until this hour, i.e. I think. Anyway, I am still learning what I can 
when I can. 

If I was to learn how to use JavaScript easier in my life, I think that the 
BBB and all variants would be an easier task for me. This is esp. true with 
all the sensors we can get our hands on.

...

So, 

If you are working 
on, http://www.ecma-international.org/ecma-262/6.0/ECMA-262.pdf, JavaScript 
and you want to learn alongside with me with the BBB and the various boards 
produced by the bbb.io persons, just chime in.

Seth

P.S. Although my time is limited, I would like to start on a project with a 
couple of people who are looking to not know all too much but would like to 
try to learn how to know things. Seriously! This is now a discussion. Oh 
and does anyone know what form of JavaScript we are using in our BBB or can 
we just pick and choose? Aw!

[beagleboard] Re: ECMA-262/2015

[Mala Dies]

Hello Again,

I asked this/these question(s) earlier because I need a BBB pal. I am 
planning on picking up some type of sensor and working with it for fun. 
Now, I have found a site called analog.com. Analog.com has a Wiki with a 
Linux reference, 
e.g. https://wiki.analog.com/resources/tools-software/linux-drivers-all. I 
was thinking we could pick some type of sensor and then go from that point.

Seth

P.S. We could we, we, we, all the way home or make bacon. I say we make 
bacon. So, if you would like and if you are interested, let us discuss and 
each purchase a Linux compatible device to test out with software. 
Hopefully, we can use Python or JavaScript. Who knows? I could learn a 
thing or two.

Re: [beagleboard] RE: Um...My Temp in F Degrees is the Same as the C Degrees/Dang!

[Mala Dies]

Hello Rob,

Seth here, again. I tried out the *(reading.value / 4096.0) * 1800;* in the 
software. It tells me that I have a temperature of -49.99 degrees in 
Celsius. I am trying to make believe my calculations from the software are 
correct with the inside/climate controlled temp. in this house. 

...

49 degrees in Celsius is 120.xx in Fahrenheit. This seems extreme. It is 
extreme. I have my temp on 80 degrees in Fahrenheit. I was expecting a 
degree in Celsius of 26 or 27 from my reads. If you have any ideas, please 
let me know. I am pretty sure you are very busy and do not have complete 
time to dedicate to me. I understand completely.

Seth

P.S. Oh and I cut out the temp. transfer from Celsius to Fahrenheit in the 
software. This is how the 49.xx came to be. I tried more than one TMP36 
sensor. I will keep trying for this project I plan on keeping in time. 
Oh...is there a type of ADC we are using that can be researched? Can I find 
this ADC name and brand in the SRM?

Oh *SNAP*,

I think I may be on the wrong board. I just realized I have been using the

Seth

P.S. I will get back to everyone soon. Sorry for this issue.

Hey Again,

I am using an image 
from http://elinux.org/Beagleboard:BeagleBoneBlack_Debian. The flasher 
image called Stretch is what I used. I did not need to type, and this is 
after *sudo connmanctl* is entered in the prompt, *wifi enable* or *wifi 
scan*.

Seth

P.S. Get back to me. I may be able to help you.

Hello Again,

Did you try sudo instead of just connmanctl? If so, I am at a standstill. I 
have to use sudo connmanctl to run my set-up for the WiFi. 

Seth

P.S. If you try a newer version of the listed images, I am sure it will 
work. You can *skip* the wifi enable and wifi scan if you use the newer 
images. You can start with services and agent on.

[beagleboard] Re: Um...My Temp in F Degrees is the Same as the C Degrees/Dang!

[Mala Dies]

Hello Dennis,

Seth here. Thank you for all that info. I will look further into the 
specification sheet on this particular product. Now, I know this is not 
your issue but here goes...

I try to finish each book I get, i.e. no matter the changes in the kernel, 
image, and/or software I use. It is just a hobby for me as of now. I get 
the V and mV difference. I get basic math but I was unaware of the offset. 
The book, Programming the BeagleBone Black (Monk), stated something 
different. I was not expecting to see my readings as similar values. I 
understand a little more now.

The book had the readings at various temperatures, e.g. Fahrenheit was a 
completely different value compared to Celsius. This is the only reason I 
am in awe. I thought it was as easy as software, hardware, book, and 
understandings. I know now that I will need to delve deeper into learning 
before asking anything.

Seth

P.S. Sometimes I take time out to try out new books and software on the BBB 
and the other variations of that specific board. I am far from a "real 
McCoy" programmer that knows everything. I really do appreciate you helping 
me to better understand.

[Mala Dies]

Hello Dennis,

Seth here, again. Thank you again for all this info. I will look into it. 
It may take me a while to reply next time. I need to order some POTs and 
try the task at hand. 

Seth

P.S. I could have burnt it out a while back on the TMP36. I will try a 
different pin too. I should be able to get back to you on the different pin 
soon.

[beagleboard] RE: Same Ole Game, Different Take/Seth

[Mala Dies]

Hello,

I have another set of software that I picked up along the way, i.e. 
probably from that book, "Evil Genuis," series from Mr. Rush. Anyway, here 
goes it. Oh but first, I know people are getting tired of seeing the same 
ole, same ole. This does not discourage me from posting.

*var b = require('bonescript');*

*var inputPin = "P9_40";*

*getBeagleTemp();*

*function getBeagleTemp() {*
*var value = b.analogRead("P9_40");*

*var millivolts = value * 1800;*
*var x = (millivolts - 500)/10;*
*var z = (x * 9/5) - 32;*
*setTimeout(getBeagleTemp, 1);*

*console.log("x=" + x + "\tz=" + z);*
*}*

Now,

I tried this software some and changed it a bit to suit my needs. As you 
all know, I am not 100% legit in the programming field, i.e. even though I 
try. 

I am getting temperatures in the Fahrenheit of 201 and in Celsius of 129. 
This is not my temp. in the house. 

Seth

P.S. If anyone has any other recommendations, please let me know. Please 
let me know what you think.

[beagleboard] Re: Same Ole Game, Different Take/Seth

[Mala Dies]

Hello Dennis,

Yep...I changed the wiring and changed a uEnv.txt file in the /boot 
directory. I have the P9_40/AIN1 pin connect now instead of the P9_39/AIN0. 
When I stated that I changed a file, I changed the file to enable 
BB-ADC1,BB-ADC2 instead of having it enabled at BB-AIN0, BB-AIN1. 

The software is completely different too. I used this set of software to 
check the TMP36 just like the older software I used in a post not too long 
ago.

Seth

P.S. I will work backwards like you are discussing and I will keep trying. 
I know I should have some pins enabled with my Cape Universal disabled. I 
am probably way off base but this is what I have done so far. Sorry for not 
giving every detail. I will wait to hear from you again while attempt to 
work some magic.

[beagleboard] Re: Same Ole Game, Different Take/Seth

[Mala Dies]

Hello Again Mr. Dennis,

Seth here. I have done some small time work on what wiring I have 
concocted. Here goes:

TMP36:

Pin 1 is + Vs and it is connected to P9_34 or GNDA_ADC.

Pin 2 is Vout and it is connected to P9_40 or AIN1.

and...

Pin 3 is GND and it is connected to P9_03 or VDD_3V3.

Now...I have been wrong before and I am just listening to the info. from 
the book. I will do some extra research on this project from the 
schematic: 
http://www.analog.com/media/en/technical-documentation/data-sheets/TMP35_36_37.pdf.
 
I got this link from Digi Key. They still sell these TMP36 sensors. 

Seth

P.S. If you get bored, let me know what you think. Oh and I just changed 
the uEnv.txt file in the /boot directory to 
enable=BB-AIN1,BB-GNDA_ADC,VDD_3V3 and then I rebooted the machine. I am 
getting an exact read of the 130 C degrees and 201 F degrees. I think this 
will better suit your needs if you are choosing to still help me out. Thank 
you again, sir.

I read the schematic on the book. The book states via photo to wire things

Re: [beagleboard] Re: Same Ole Game, Different Take/Seth

[Mala Dies]

Hello,

The instructions on the book said to connect the pins of the TMP36 via 
jumper wires to the BBB/BBGW in that manner. I am using a BBGW instead of 
the BBB or BBBW for this project.

Seth

P.S. Should I have the jumper wires connecting to different pins on the 
BBGW?

Hello,

So,

TMP36:

+ Vs is now at VDD_3V3

GND is now at DGND

I did configure the old software to work but this is easier.

Re: [beagleboard] Re: Same Ole Game, Different Take/Seth

[Mala Dies]

Hello Sir,

Supposedly, the GNDA_ADC pin on the BBGW makes less noise. This noise would 
create a higher fluctuation of distance from the actual temp. in the 
environment. 

Seth

P.S. Now, the GND to VDD_3V3 had some idea behind it but was not listed in 
the book. I had to put value at 63 degrees Celsius but it was still off by 
about two degrees with the old software and old hook-up. Now, the temp. is 
still off by about 10 degrees in Fahrenheit with the correct hook-up and 
current software.

[Mala Dies]

Hello,

I am using a couple different books. I am using the Programming the 
BeagleBone Black from Monk and another book called Evil Genius by Rush. It 
is a similar book on the BBB. I had some odd connections at first. You are 
right. I guess I am learning what I am doing.

Seth

P.S. I lost track of all the info. I have accumulated over the last year. I 
will try to keep better records. If you have any questions, let me know. I 
will look up some items on what I am discussing. I got the readings from 
the BBGW to list Celsius and Fahrenheit near what the house is listing on 
the dial. I am still about 10 degrees off, though.

[beagleboard] TMP36 and Software and The Info. Was Correct/Seth

[Mala Dies]

Hello,


This is the print or reading from the software I produced from the book. It 
works.


I tried a BBB with Grove Cape and it shut the board down and would not 
power on. I tried it on the BBGW and it fried my TMP36 sensor. I touched 
the sensor and it was blistering hot. I got burned, i.e. you mothers.


So, in hindsight, I will stick with the BBB and BBBW for now. I have an 
older  model that is only 2GB. It worked right from the get-go.




Here is the software and it works with GNDA_ADC and pin 'P9_40'.


var b = require('bonescript');


function readTemp() {

   b.analogRead('P9_40', displayTemp);

}


function displayTemp(reading) {

   var millivolts = reading.value * 1800;

   var C = (millivolts - 500) / 10;

   var F = (C * 9/5) + 32

   console.log("C = " + C + "\tF = " + F);

}


setInterval(readTemp, 9000);


So...all is well that ends well.


Seth

[beagleboard] Re: Python program using PWM Not Working at Autostart

[Mala Dies]

Tomas,

Did you try the Autorun directory in the Cloud9 IDE? Oh and that is an 
older distro. You can type sudo -i to get into root if you are not root 
already. One last thing...you may want to update your image and then use 
cron if possible. This is another option. 

Seth

P.S. You can actually do a grab and drop in that IDE. Just grab the file(s) 
and drop them into your Autorun folder. I tried doing this a while back and 
it worked. If I come across the way to do it with Debian again, I will post 
again.

Hello,

The other day is when I did some incorrect measurements and almost burned

I can test my GPIO pins in the Debian distro with our commands?

Seth

P.S. I do not want to test them via hardware. I thought there might be a

Hello Graham,

Seth here. Okay, I will just check to see if they are working. I thought 
the distro could detect our hardware and if it was in working order or not. 
I know of the *i2cdetect *command to see if the hardware is available but I 
thought there was a software to detect if the hardware still was working. 

Seth

P.S. Thank you for your input. I will check out the looping function for 
output. I might just see if the multi-meter can read the respected volts 
from the pins "I ruined." Thank you, again.

[beagleboard] "What Was I Thinking" and Learning How Sensors Might Work/Seth

[Mala Dies]

Hello,

I know I have bugged the community with issues pertaining to my TMP36 
sensor and its technology and the BBB (and all variants "sometimes 
including Capes").

Here goes:

...cough.

Um, Why would I attach a male to male lead from 3.3v on the BBB to GND on 
the TMP36 sensor?

Easier:

*BBB* (3.3v) or P9_03 *to **TMP36* (GND) or Pin 3

I think this is my question. Please try to answer with some type of 
understanding for me.

Seth

P.S. I have found some more items regarding this TMP36 sensor, i.e. like 
why I am attaching the lead to the BBB on GND_ADC to TMP36 on Pin 1? I 
found the info. to the TMP36 sensor 
at 
http://www.analog.com/media/en/technical-documentation/data-sheets/TMP35_36_37.pdf.
 
Anyway, if you have time one day, please try to make me understand. I 
thought GND goes to GND with the lead for some reason.

Hello,

Okay...

TMP36 to BBB:

Pin 3 to 3.3v

Pin 2 to P9_40 (GPIO/Analog)

Pin 1 to P9_34 (GND_ADC/Low noise GND)

I think this should help. I am making a temperature sensor tell me what the 
temp. is inside for now.

Seth

P.S. I appreciate you reaching out. Please let me know of what other info. 
I need to furnish.

Hello Sir,

I cannot just run a .js file with sudo nodejs temp.js on my BBB. The issue 
pertains to nodejs not being installed or something. I went to the 
npmjs.org site and found bonescript and tried to start from there. I also 
tried nodejs.org to find info. on how to get it on the BBB. 

Seth

P.S. I am coming up short for some reason. I did some work with what the 
sites have listed at https://www.npmjs.com/package/bonescript 
and 
https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions.
 
If you or if anyone else is having trouble, please give some advice.

[beagleboard] Re: "What Was I Thinking" and Learning How Sensors Might Work/Seth

[Mala Dies]

Hello Mr. Dennis,

I am going over the book, "Programming the BeagleBone Black," (Monk 2014) 
and I found on page 110 a TMP36 software example with relating a P9 Header 
layout/diagram. I think I am connecting things correctly. I have done this 
example before but currently I am having trouble with the 2GB BBB and 
Debian Stretch.

Seth

P.S. I am trying to read a TMP36 temp. sensor to tell me Celsius and 
Fahrenheit on my command prompt.

Hello Mr. Jason,

Seth here. I am not perfect with JavaScript but I thought working on the 
same page might work better than working alone. Thank you for the link. I 
will look into it. 

Seth

P.S. I will try out your link and learn from there. I appreciate you and 
your team making this available for everyone, esp. me. Thank you again and 
I will try node.js more often. I read a bit online on their site but I keep 
getting side tracked with JavaScript, bonescript, and running .py files. 
Hey sir, does the JavaScript language have the ability to be run from the 
command line outside of node.js?

[Mala Dies]

Hello,

Look at this photo in .jpeg format. 


<https://lh3.googleusercontent.com/-Hp4z5F5f99Q/WY4MODl2vCI/J1A/CmcRfoKVu3kfqHPIsLOUqlkS41l0fbWzACLcBGAs/s1600/forBBBTMP.JPG>



I would assume the left most *pin* on the TMP36 temp. sensor when facing 
left, away from the board on the left side of the board, would be *Pin 3*, 
right?


Seth


P.S. If you have time, please review the photo and get back to me. I have 
made mistakes before but I think I am correct.

Hello,

I guess I am making the flat side of the TMP36 sensor face left on the left 
side, i.e. the flat face is facing away from the BBB when I add the leads.

Hello Mr. Dennis,

Seth here. I do not believe this stuff. The item I was viewing was from the 
underneath view/bottom view. Silly! I read that many times and it never 
clicked. Thank you. I feel completely inadequate to post after this screw 
up but I will again. 

Seth

P.S. Thank you again for your support. Oh and I was using AIN1/P9_40 for 
this software instead of P9_39. I did not want to plagiarize the OpenSource 
info.

As many of us already know, I am working with the TMP36 and failing harder

software. It is stating that the BBB cannot find the 'bonescript' language 
that I am invoking. 

Seth

P.S. How can I put the 'bonescript' language in my PATH so when I run the

[beagleboard] RE: No Cloud9 IDE on 2 GB and This May Have Something to Do With the Lack of Bonescript/Seth

[Mala Dies]

Hello,

Most of you know already that I have been testing out old software with 
newer kernels and new, updated .img files. I noticed that when I look for 
the Cloud9 IDE on the 2GB version of the BBB, I come up empty.

Here:

*uname -a* gives me *Linux beaglebone 4.9.37-ti-r47 #1 SMP PREEMPT Thu Jul 
13 22:48:49 UTC 2017 armv7l GNU/Linux*

Should I update to the latest version of Stretch, i.e. 08-06-2017?

Seth

P.S. I guess I just need some updates. Who knows?

Re: [beagleboard] Re: Making uEnv.txt Suit My Needs and Running Software/How Do I Put 'bonescript' in My Path...

[Mala Dies]

Hello Sir,

I tried this out. I used that BASH command and it did not locate my 
node_modules under /usr/local/lib for some reason. I have the 2 GB version: 
Linux beaglebone 4.9.37-ti-r47 #1 SMP PREEMPT Thu Jul 13 22:48:49 UTC 2017 
armv7l GNU/Linux. Should I update to the latest release of Stretch?

Seth

P.S. I do not even have node on my system right now for some reason. Oh and 
I do not have bonescript located anywhere on my machine either. This is the 
issue since I am using an invocation of 'bonescript' via *var b = 
require('bonescript'); *in a .js file.

[beagleboard] Re: No Cloud9 IDE on 2 GB and This May Have Something to Do With the Lack of Bonescript/Seth

[Mala Dies]

Otay and Hello,

Seth here. I figured out what happened. I found the 1GB Stretch, Console 
.img file and downloaded it. I then applied it to my board, i.e. the BBB 
2GB. Oops! Anyway...is there a 2GB .img file for the BBB with the weekly 
snapshots of Stretch?

Seth

P.S. I thought since I had the console .img file, I could use it but only 
without the GUI, e.g. only the command line interface.

What does a console image actually entail, e.g. no GUI, no Cloud9 IDE,

[beagleboard] Re: UART1 Isn't Reading

[Mala Dies]

Hello,

My name is Seth. Tomas, you may need to add the *BB-UART1_TXD* and 
*BB-UART1_RXD* or whatever pins you are using in the uEnv.txt file. You can 
add these specific lines, now this is if the pins are still called this on 
your specific board, by going to the */boot* directory and finding your 
*uEnv.txt* file. This file can be altered or changed by using vim or emacs 
or nano and you would have to change the section 
*cape_enable=bone_capemgr.enable_partno=* to 
*cape_enable=bone_capemgr.enable_partno=BB-UART1_TXD,BB-UART1_RXD*. 

I am pretty sure this is how it is done. Let me know if this works.

Seth

P.S. I have tried to comment the Universal Cape section and delete the 
comment on the cape_enable=bone_capemgr.enable_partno= section to try this 
override before. It has worked at times.

Are there any people in this world having trouble with the Debian Distro

system to download Debian Stretch and I tried to sign into my BBBW via ssh 
debian@192.168.7.2 and I was rejected on multiple occasions.

P.S. I am basically using the Debian Distro on the VMware to ssh into my

[beagleboard] Re: ADC.setup() Prevents Python Program from Running at Autostart

[Mala Dies]

Hello,

Run the CRON job with EDITOR=nano crontab -e and make sure you are root. I 
forget what it must take to become root in our new systems. By default, the 
Debian Stretch Distro does not place us in the root directory. *sudo -i *will 
do it!
