pwm_init

unsigned long pwm_init( unsigned long frequency );

Description

Sets the base frequency for the pulse width modulation (PWM) 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.

This function is intended for use with the Rabbit 3000 and Rabbit 4000.

Parameter

frequency

Requested frequency (in Hz)

Return Value

The actual frequency that was set. This will be the closest possible match to the requested frequency.

Library

PWM.LIB (was in R3000.LIB prior to DC 10)
