Low frequency Hardware PWM

[Ioannis]

Are you talking PWM or HPWM? Isn't using the CCP module automatically HPWM?

My interest is in hardware PWM but PBP cannot manipulate the appropriate registers that is needed to get that low on frequency, as Richard noted.

Have not done it yet but hope to manage it.

You might consider using the Numerically Controlled Oscillator (NCO) to achieve this low frequency output.
I have recently been looking at the 16F1503 to achieve a stable 1Hz output.
This device has the ability to do both 50% duty cycle (my particular interest) as well as PWM output.

Agreed, this is not something that is doable directly from PBP commands but is quite manageable with register manipulation.

Thanks Barry.

Never thought of that NCO.
