So I have a project that is going to use audio and need to do some PWM to control a motor. As I understand it (and I could be very wrong here), there are two chips a pi can use to produce PWM. In the documentation, the RPIO library has settings for
DELAY_VIA_PWM the default. Both of those are hardware PWM, right? PCM references the other chip that is not the default audio chip?
The one other reference to
DELAY_VIA_PCM I can find on the web claims it is "sw" pwm, which I assume they mean software.
So with RPIO will I be able to use the
DELAY_VIA_PCM setting to get hardware pwm, and still leave my audio channels available?
