Synopsis

int sub_fpwm_config( sub_handle hndl, double freq_hz, int flags )

Configure fast PWM module.

Parameters

•freq_hz - Desired fast PWM frequency in Hz. Frequency can be in a range 8MHz .. 0.238Hz

•flags - Set of configuration flags listed below

FPWM_ENABLE	General fast PWM enable. If this flag is not set fast PWM module will be disabled and FPWM outputs will go to HiZ.
FPWM_EN0	Enable FPWM_0 output. Otherwise FPWM_0 will stay low.
FPWM_EN1	Enable FPWM_1 output. Otherwise FPWM_1 will stay low.
FPWM_EN2	Enable FPWM_2 output. Otherwise FPWM_2 will stay low.

Return value

On success function returns 0. Otherwise error code.

Example

Enable fast PWM module with FPWM_0 and FPWM_2 outputs.

PWM frequency 10.6Hz

sub_fpwm_config( hndl, 10.6, FPWM_ENABLE|FPWM_EN0FPWM_EN2 );
