int pwmOutConfig(unsigned long frequency);
int pwmOut(unsigned int channel, float dutycycle);
Sets the base frequency for the PWM pulses and enables the PWM driver on all four channels. The base
frequency is the frequency without pulse spreading. Pulse spreading (see pwm_set) will increase the
frequency by a factor of 4.
frequency is the frequency (in Hz).
Actual frequency set. This will be the closest possible match to the requested frequency.
Sets a voltage (0 to VDD on an analog output channel according to the percent duty cycle of the 1024-
clock-count cycle.)
channel is the output channel to write to (0–3).
dutycycle is the percent duty (or on) cycle value of the 1024-clock-count cycle (i.e., 0.25).
0 if successful
-1 if an invalid channel number is used
-2 if an invalid duty cycle was requested
