This should work:
1 - Set your port pin to GPIO mode, just as if you wanted to use it as normal output.
2 - Get the #defines from the include file I've attached.
3 - Use the code below
pin_number is in range 0...15.
value is one of the empirical values from one of my previous posts.
I never tried to fully understand how the PWM values work.
I've also attached my full relay driver source file. That's most likely not gonna compile outside of my project, but could have some use as an example anyway.

Code: Select all
uint32 pinaddr = GPIO_PIN_ADDR(GPIO_ID_PIN(pin_number));
GPIO_REG_WRITE(pinaddr, GPIO_REG_READ(pinaddr) | 1);
GPIO_REG_WRITE(GPIO_SIGMA_DELTA, pwm_value);
