Background PWM on SX28 using minimal cycles (0.6%)

Bean

I thought I would share my code to create a 1KHz background PWM signal on the SX28 using the internal 4MHz clock and using the bare minimum of cycles.

Here is what I came up with. The interrupt is only called twice for each PWM cycle (to toggle the pin). According to SX-Sim the interrupt uses 12 cycles. It is called 2000 times a second, so that is 24_000 cycles per second of the 4_000_000 cycles. Comes out to 0.6%

Enjoy,

Bean

I'm all over that. Saved.
I have to try it out on my new RGB LEDs.
Thanks
