Function Documentation

delay_ms()

void delay_ms

(

uint32_t

time_ms

)

Simple bus-wait helper.

Parameters

[in]

time_ms

Time in ms to wait (unsigned 32-bit).

main()

int main

(

void

)

This program generates a simple dimming sequence for PWM channels 0 to 3.

Note

This program requires the PWM controller to be synthesized (the UART is optional).

Returns

!=0 if error.
