Best way to count PWM pulse

[horizontech]

HI

I need to count 4096 pulse PWM from PIC.

I am looking for the best way to use same PIC to generate PWM and count 4096 pulses from the same PIC ?

Can I use setup_timer as counter to input PWM pin ?

Thanks for your help

Why do you want to count the pulses ? Do you want to stop sending
the pulses after 4096 have been sent ?

What is the frequency of the PWM signal ?

hi !

I need to control Led driver TLC5940 , And after 4096 PWM pulse on this IC , i need to toogle the blank Pin on the TLC5940


Thanks

You didn't post the frequency of the PWM pulses.

First of all TLC5940 does not require PWM signal, but clock signal and on every 4096 cycle there has to be SYNC signal. And this clock can be up to 30MHz.

[PCM programmer]

I know that. But I assume that he wants to use the CCP, either in
PWM or Compare mode, to generate the GSCLK pulses. But how
it's done, or whether it can be done at all, depends upon the desired
frequency of the pulses.

We agree on that

there could not be less information from horizontech about topic.
