Re: [beagleboard] Cloud9 Blank White Screen

Sorry to reboor this thread, but the same problem occured on my Bone. I have been working on it locally last week and since then I can't access it from my laptop anymore. I'm kind of at a loss here, because I do need the rmote connection every once in a while. It seems that it is indeed a probl

You need to edit the file to uncomment the includes for the serial devices (ttyO1 and so on). git status should then give you the difference of your edits against the repository. On Friday, May 22, 2015 at 11:49:49 AM UTC+1, Harke Smits wrote: > > Thanks a lot for the pointer! Yes, I'm afraid, I

[beagleboard] Measure +/-10V signal with Beaglebone Black ADC inputs. IC for Voltage Translation?

Hi, I want to measure a signal with the range of -10V...+10V with a BeagleBone Black ADC input. Therefore I designed a unidirectional voltage translator with an op amp to bring down the voltage to the 0...1.8V input range of the ADC input. Now, the thing is, that I also want to be able to switc

Here is some code from a Beagleboard (not Beaglebone) the register bases and pin configs will be different, but it should give you an idea of how to control a PWM using QNX. It is *not* a driver in the QNX sense, but a low-level approach. #include #include #include #include #include #inclu
