[originally posted by Anonymous on 2013-03-01 07:11:28] This PWM program has a problem, perhaps due to the order in which operations occur and how data get stored. If you run: pwm1.start(pwm1pin) pwm2.start(pwm2pin) pwm2.SetDuty(3000) pwm1.SetDuty(1000) the PWM1 output gets screwed up. Change the order to: pwm1.start(pwm1pin) pwm1.SetDuty(1000) pwm2.start(pwm2pin) pwm2.SetDuty(3000) and the program works fine. I tried to debug the original pwmAsm.spin, but gave up. Use caution.
