I would really like to use the 16F628A hardware PWM to run an RC servo at 60 Hz. My program is busy getting input and can’t be interrupted 60 times per second to send output. I could use a second PIC for output but would rather not. This note is in the Mid-Range MCU Family Reference Manual.
Note: The Timer2 postscaler is not used in the determination of the PWM frequency. The postscaler could be used to have a servo update rate at a different frequency than the PWM output.
Googling found a lot of complaints quoting that note and saying that the postscaler has no effect.
I am still looking but has anyone had success with this or is it misinformation?
