Hi All, Running UDOObuntu_beta 12.04, kernel 3.0.35. I am not using an Arduino sketch. What I can't figure out how to configure Ai and PWM in sysfs. PWM: I need to "echo" , polarity, duty, period and run in /sys/.....? Analog input: No idea.... Hope there is somebody who can kick me in the right direction...... Regards, Maba
