Detailed Description

Run up to 32 channels of low speed PWM (up to ~10kHz@80MHz clock).

No external hardware beyond the PWM devices is needed. Works with H bridges, LEDs, servos, and anything else that takes a repeating PWM signal.

Constructor & Destructor Documentation

PWM32::PWM32 ( )

inline

inline

Output a PWM wave with a calculated duty.

Parameters

pin	The I/O pin to use (0..31)
duty_cycle	The duty cycle (0..100) to use. 0 is off, 100 is full on.
period	The period (in uS) of the cycle.

inline

Output a series of square waves with a high time of on_time microseconds, and a period of (on_time + low_time) microseconds.

Parameters

pin	The I/O pin to use (0..31)
on_time	The duration of the high time, in uS.
off_time	The duration of the low time, in uS.

inline

Output a servo compatible pulse with a period of 20ms.

Parameters

pin	The I/O pin to use (0..31)
pulse_width	The width of the servo pulse in uS. Can be any value, but most servos require a range (1000..2000)

void PWM32::Start ( void )

inline

Start a cog with the PWM runner.

Here is the call graph for this function:

void PWM32::Stop ( void )

inline

Stop the cog, if running.
