I have a project that requires a USB interface, but also has to process events on a strict timer schedule.
So does anybody know the maximum number of cycles that the USB interface will take, before releasing control back to the main code?
What I'm after is three PWM outputs, with 8 bit resolution at greater than 250Hz, which only gives 16uS steps.
