Hi, Interesting task you have ahead. while it can be done with the BeagleBone Black their could be issues with accurate PWM control as the OS is not real time. If your pwm is allowed to skip a beat from time to time or is is slow enough that it is not a problem for you . . . Others please chime i

You said directly, so I thought I might add this. You can take a PIC16Fx with integrated ADC's and set up your joystick's pots in voltage divider mode. To explain, you hook up your VCC to one end of your pot and then take the voltage as sunk through another fixed resistor to ground. Ask me if I

This can all be done from userspace. Seriously, how do you games that use joysticks as in input work ? All those other board mentioned are not worth the time investment, specifically for this single task. Also, I own several TI LM4F dev boards as well as the TM4C1294. The TM4C1294 has issues, but t
