Hello! so i have just got my hands on a BBB and i want to try out my quad-copter motors, and it seems like i just cant get it to spin! the following code is what i use to run, and with no luck i am no completely stuck to why it wont spin. [code] var b = require('bonescript'); var motor = "P8_13

Re: [beagleboard] Help with Enabling SPI?

I agree with William, best to stay with everything on an SDCard for now. NFS is an acronym for Network File System and means that instead of the Debian OS residing on the SDCard, it is placed on your NFS Server (which can be your Linux desktop) and when your BBB boots, it loads the Debian OS ove

Hi William, Thanks for your reply. I'm trying to flash bbb now. Could I ask what's the difference between flashing an image vs flashing the eMMC? I thought flashing the bbb meant flashing everything. I do not currently have anything that I want to keep on bbb. What's the difference between bo

Hi John, Thanks for your reply. I'm new to linux systems, much less embedded linux systems. How would I know if I'm using NFS and systemd? I'm currently in the processing of flashing bbb, so I don't know if this new version of bb will be the same as before. Also, I thought enabling the SPI w

Re: [beagleboard] Help with Enabling SPI?

I’ve had this problem myself. If you are using NFS and systemd, then you must prevent connman from managing eth0: In /lib/systemd/system/connman.service, add -I eth0 to the connmand line Regards, John > On Feb 19, 2016, at 3:44 PM, Audrey wrote: > > Hi everyone, > > I want to enable SPI0

well, if you have issues finding the bug, post the code. I'm sure someone will be able to spot / find it. On Wed, Feb 17, 2016 at 3:10 AM, hllpc wrote: > Apologies for the delay, > I spilled coffee on my notebook and it died. > > BBB rebooted > > root@arm:/home/debian# ls /lib/firmware/ | grep A

Re: [beagleboard] Help! ADC 'stopped working' overnight

4095. It's zero based, so 0 is counted too. The bitfield is LSB as far as I'm aware, but just standard bit manipulation in C should present no problems. As I've experienced none myself. On Tue, Feb 16, 2016 at 3:06 PM, Harvey White wrote: > On Tue, 16 Feb 2016 12:45:18 -0700, you wrote: > > >An

Re: [beagleboard] Help! ADC 'stopped working' overnight

Just in case this somehow helps. ADC values are represented in a 32bit bit field. But this bitfield actually has 3 fields inside of it. You can double check to make sure I'm remembering correctly. But the first 12 bits is the actual ADC value, the next 4 bits is the ADC identifier( channel ), and t

Re: [beagleboard] Help! ADC 'stopped working' overnight

OK, so another possibility does come to mind. The values you're reading are somehow becoming corrupt before you check them. So humor me here, and honestly this is probably in your best interest anyhow. . . 1. Reset your board, which is to say, reboot it, and make sure none of your stuff for

Re: [beagleboard] Help! ADC 'stopped working' overnight

Anyway, two possibilities here if the raw values are higher than 4095. 1) Your ADC need to be calibrated. I believe there is info in the TRM on this, but I have yet to fully understand this process myself. So see the TRM for details. 2) your ADC is damaged, and very likely irreversibly. On Tue,

Re: [beagleboard] Help! ADC 'stopped working' overnight

You need to see what raw values are being read out of the ADC. If they're higher than 4095, then you've got a problem - Which I'd guess would be a bad ADC. Passed that . . . voltage = ( raw_value / 4095 ) * scale Where scale = highest possible voltage to be read in. Then of course max voltage o
