I'm trying to build a differential drive robot using some 6v motors with encoders from Pololu. Their amperage exceeds the capabilities of the built in motor controllers on the BB Blue.
I've got a larger separate motor controller that will accept PWM signal for control. Question 1: Which physical connector on the BeagleBone Blue do I connect to in order to access 2 channels of PWM? I'm not clear how PinMux <http://www.strawsondesign.com/#!manual-pinmux> works as described in the manual. I'm assuming it means that once I figure out which physical connector to attach to, that I can then change the functionality to PWM. (Seems like perhaps the GPS connector is the correct one??) Unfortunately the online manual doesn't seem to give practical example code of this functionality. Question 2: Is it possible to access the PWM signal of the built in motor controllers? This would be ideal as then the external motor controller would be functionally transparent to the roboticscape software that already exists. Again, I can't figure out if this is possible or which connectors to tie into to access the PWM signal that drives Motor Channels 1 to 4 Thanks in advance for any help you can provide. - Phil -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
