Re: [beagleboard] miniDisplay Cape - Looking for sample code
Mark,
ahh right that was already fixed, i am not sure how i uploaded an older
version where it wasn't fixed...
i'll update the tarball and add links to your code as well...

I've alse changed the code a bit so Boris will render much faster. Rather

fillScreenBards(). Here's my displayimage().

tbuffer[j+1].type=1;
tbuffer[j+2].data=(*pixel[0]* 0xff);
tbuffer[j+2].type=1;
j +=3;

// SPIWriteChunk(buff_ptr, 128*128*3);
for(i=0;i128;i++){
SPIWriteChunk(buff_ptr, 768);
buff_ptr += 768;

*Why do you only write 768 bytes at a time to the SPI?*
With only small changes the code here[1] drives the miniDisplay and sends
a bmp file to it.

It works! Thanks. Though the background on Boris is greenish.
that is odd! we've not had any reports of that issue during our testing.
it is possible that the SPI timing could be off giving you a slightly
shifted color spectrum, or possible the display is damaged. please email
sup...@boardzoo.com and we'll get another minidisplay cape out to you to
test...
There is a typo on the wiki. The tar command produces a directory
called Minidisplay-example with a capital M.
sorry about that, the elinux.org wiki automatically makes the first
letter of file uploads a capital. the original file was not capital
I also had to run echo -10 /sys/devices/bone_capemgr.*/slots
before echo BB-SPIDEV0 /sys/devices/bone_capemgr.*/slots to disable a pwm
that was in conflict.
had you previously loaded another device tree entry with PWM?
Thanks again...
i did not get a chance yesterday to document it, but the header file for
the boris image was generated using GIMP's export feature. it would be easy
enough to add a parser to decode bmp or png files...

Re: [beagleboard] miniDisplay Cape - Looking for sample code
Mark, the stock BB-SPIDEV0-00A0 device tree entry will enable the SPIDEV device driver. once that is done, you can talk directly to the lcd from userspace. we have a small C demo program that allows you to read an image file and display it on the lcd. this should be easy enough to do from any of the other scripting languages as well. i'll get that pushed to the wiki page later today. there are a number of existing examples of people using similar lcd panels with arduino and other dev boards: http://engineersofthecorn.blogspot.com/2012/06/beaglebone-and-adafruit-18-spi-lcd.html http://blog.inbedded.net/blog/2013/06/02/beaglebone-black-and-lcd-equals-fun/ http://guy.carpenter.id.au/gaugette/2014/01/28/controlling-an-adafruit-spi-oled-with-a-beaglebone-black/ Dave On Tuesday, July 15, 2014 12:10:59 PM UTC-5, Mark A.

I am doing a Masters project in control systems at university and am hoping to either not have any external boards or at least very minimal. I will probably make my own board and won't add an RTC if I can implement one with what is already on the BBB, especially as it may have more features such as wake ups which a general I2C RTC won't have I don't think.

Re: [beagleboard] BeagleBoard SBC Goes OEM, COM Version Coming
Short and Sweet BlueSteel-Basic and all other BlueSteel products are manufactured in the Richardson, Texas on site of Circuitco. the benefits for BlueSteel products have been carefully considered to provide the follow benefits: * no restrictions on commercial usage * volume price discounts * Enable Third Party Software Vendors to provide commercial SDKs * all I/O is available on the expansion header as an OEM/ODM developer, the BeagleBone Black presents a great starting point, however it does present a number of obstacles, in that BeagleBoard.org has significant restrictions on the use of the BeagleBoard logo and the use of the board in commercial products: http://www.elinux.org/Beagleboard:BeagleBoneBlack#Terms_of_Use In addition, there a limited set of authorized distributors who can sell BeagleBone Black, and they are limited in the number of boards they can sell to a single customer. For example you can look at the Adafruit website: *Limit 1 (one) per customer, orders cannot be combined.* http://www.adafruit.com/products/1876 Another aspect is that most OEM/ODM developers who are including the BeagleBone Black (in violation of the terms of use) want to have the full set of I/O on the expansion header so that they can implement their own features on a daughter board. It is far easier to add a feature you need on a daughter board, than to remove features you don’t need from the main board. This very same principle of commercial usage has already been recognized by Embest which has released their own version of a BeagleBone Black clone for the same target market.

It is good news that you are working with Robert on Debian. IMHO this is the way to go. Robert is doing so much for the BBB community. TI should support him in every way they can. It is a fact that BBB developer resources are extremely limited. So efforts should really concentrate on getting the serious stuff working properly, I mean the basic things a serious developer needs: kernel + stability + Qt, because Linux is used for touch GUIs, not as a desktop replacement.

This is definitely not the case and will never be! Just have a look at all the posts in this thread. just a reminder, TI has nothing to do with BeagleBoard.org other than selling Circuitco the chips to manufacture the beagleboard products it's circuitco and beagleboard.org that are working with Robert. Dave The LCD Cape vendors should push support for their hardware into https://github.com/beagleboard/kernel and https://github.com/beagleboard/cape-firmware. CircuitCo does so. Github pull requests are the best way to do so. The problem with touch was that someone ported the ADC / touchscreen stuff from an upcoming TI kernel to the 3.8 kernel and some things broke. Then this somebody just did not have the time to fix the bugs and they stayed there. I already discussed this in another thread.

I totally agree. Nobody would buy a BBB for $150 when you can get a Raspberry Pi. But prices of other HW components have probably also dropped significantly since the old days. here is the thing: in 2007 when beagleboard was started, the only other open hardware platform that was available was the arduino. the idea of an open hardware platform was very new. in addition in 2007 you could not purchase an arm development platform for less than $1000USD! beagleboard was the FIRST arm development platform that cost less than $200 and it was the FIRST arm open hardware platform so beagleboard has been and always will be the driving force for low cost open hardware platforms...

If the software sucks then to the average Joe Bloggs the hardware then also, well, sucks. If Joe Bloggs buys a BBB and a cape made by the same company, and there is a recommended software to go with it which claims compatibility, then Joe Bloggs would rightly expect that the BBB + CAPE + OS will run as advertised, and this isnt the case. I personally am using but a fraction of what the BBB is capable of doing, however I wouldn't have thought using a BBB made by CircuitCo and a LCD Cape made by CircuitCo, running the recommended OS with everything as default, and finding that the touch does not work and things like the mouse pointer jumps all over the screen, kinda not fit for purpose? If someone like me buys a BBB + Cape and uses an OS which is recommended and claims compatibility, and finds that it doesn't work for something as fundamental as the touch screen, is that classed as user error? I personally think not. I stand by my comment of it being a flop, as if the company does not make a profit after selling 100K of a popular product, then really... what was the point. And in terms of sales and people not being able to get stock, you have to start to wonder how many of those are from users reading the marketting and thinking that will be great, to find when they get it they have no idea how to fix problems they encounter (like me) and so cannot use it as they wanted to. Many of the happy people probably dont use Capes as you said. It just sucks that the people who designed the cape also design the BBB, and they dont work right purely due to the Software.

[beagleboard] Re: SPI1_D0 and SPI1_D1... what's MISO, whats MOSI?
Thomas, unlike most microcontrollers, the AM335x allows the MISO/MOSI pins to be software definable. one of the reasons behind this is to help with the pcb layout. when designing complex boards, sometimes it is easier to have these definable help prevent the signals having to cross during layout. we have a wiki page that talks about setting the SPI character device driver with some examples of defining how MISO/MOSI are mapped to the D0/D1 pins: http://elinux.org/BeagleBone_Black_Enable_SPIDEV Dave On Wednesday, November 27, 2013 1:13:04 PM UTC-6, tond...@gmail.com wrote: I need to find out what the *Pins 29 and 30* on Pin *Header P9* (SPI1_D0 and SPI1_D1) are.

[beagleboard] Re: GPIO used before purchase
while you can use all of the pins as GPIOs it will greatly reduce the features available on the BBB. you should consider carefully what you are using the GPIOs for and then look to offload some of the GPIOs to a I2C based GPIO expander such as the TCA6408 or TCA6416.

Jason,
shouldn't this info go up on the elinux.org wiki?
Absolutely. Any recommendation on the page location? I will upload it right
away.

There are lots of ways to extract the contents of the eMMC to save off
and
reuse. I'm proposing a method using Buildroot and an initramfs such that
you can simply drop a few files from a .zip onto a normal, FAT-formatted
SD
card to perform the extraction. There are several things really handy
here,
such as the ability to edit autorun.sh to be whatever script you want to
run on your board at boot. In the archive, I only have the necessary
autorun.sh for *saving* your eMMC content. The flip-side is provided
here
in the text such that you need to go through a couple of steps before
you
trash your eMMC.
The steps for saving off your eMMC contents to a file:
* Get a 4GB or larger uSD card that is FAT formatted.
* Download
https://s3.amazonaws.com/beagle/beagleboneblack-save-emmc.zipand
extract the contents onto your uSD card.
* Eject uSD card from your computer, insert into powered-off BeagleBone
Black and apply power to your board.
* You'll notice USR0 (the LED closest to the S1 button in the corner)
will
(after about 20 seconds) start to blink steadily, rather than the
double-pulse heartbeat pattern that is typical when your BeagleBone
Black
is running the typical Linux kernel configuration.
* It'll run for a bit under 10 minutes and then USR0 will stay ON
steady.
That's your cue to remove power, remove the uSD card and put it back
into
your computer.
* You should see a file called BeagleBoneBlack-eMMC-image-X.img,
where
X is a set of random numbers. Save off this file to use for
restoring
your image later.
Because the date won't be set on your board, you might want to adjust
the
date on the file to remember when you made it. Delete the file if you
want
to make room for a new backup image. For storage on your computer, these
images will typically compress very well, so use your favorite
compression
tool.
To restore the file, make sure there is a valid
BeagleBoneBlack-eMMC-image-.img file on the uSD card and edit
autorun.sh with your favorite text editor to contain the following:
#!/bin/sh
echo timer /sys/class/leds/beaglebone\:green\:usr0/trigger
dd if=/mnt/BeagleBoneBlack-eMMC-image-X.img of=/dev/mmcblk1 bs=10M
sync
echo default-on /sys/class/leds/beaglebone\:green\:usr0/trigger
*NOTE*: Be certain to replace the 'X' above with the proper name of
your image file.
This image was built using Buildroot. The sources are at
https://github.com/jadonk/buildroot with tag save-emmc-0.0.1. Download
via
https://github.com/jadonk/buildroot/releases/tag/save-emmc-0.0.1 or
clone
the git repo. It is a small fork from
git://git.buildroot.net/buildroottag
e9f6011617528646768e69203e85fe64364b7efd.
To build, 'make beagleboneblack_defconfig; make; ./mkuimage.sh'. Output
files (am335x-boneblack.dtb, MLO, u-boot.img and uImage) will be in the
output/images subdirectory. The following files were created manually.
uEnv.txt:
bootpart=0:1
bootdir=
fdtaddr=0x81FF
optargs=quiet capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN
uenvcmd=load mmc 0 ${loadaddr} uImage;run loadfdt;setenv bootargs
console=${console} ${optargs};bootm ${loadaddr} - ${fdtaddr}
autorun.sh:
#!/bin/sh

dd if=/dev/mmcblk1 of=/mnt/BeagleBoneBlack-eMMC-image-$RANDOM.img bs=10M
sync
echo default-on /sys/class/leds/beaglebone\:green\:usr0/trigger
The kernel is based on
https://github.com/beagleboard/kernel/commit/9fdb452245a58158a4bea787cdc663c17681bcfe,
but I applied the patches, added firmware and uploaded it to
https://github.com/beagleboard/linux/commit/ddd36e546e53d3c493075bbebd6188ee843208f9to
pull down in the Buildroot makefile. The link to the source for the
firmware is in the commit.
I've applied to join the Buildroot mailing list to send these patches
upstream. The power management firmware is not yet loading properly, but
that is something I can look into.
Happy hacking!
