Why do you need 200 or more refreshes per second ? Aren't you controlling lights ? Mine is doing 8 channels, 30 times per second each (240 refreshes per second) and leaving you with 75% of your CPU cycles. There is no point updating each channel any faster than human flicker fusion. Assuming you;re still flashing lights.
What have I missed ? Your code saturates your processor and you haven't done anything else but the PWM ! I think you're scared of interrupts Steve |
