Who can help me thanks, I have to generate a PWM signal with a base at 20HZ or 10 HZ and variable from 0 to 100% ... the original component of the micro does not make me go below 1000HZ. Thanks sorry the trouble.

Hi xelites,
Sorry I did not know the link is broken.
I can create an example flowchart for you.
What would be your preferred frequency?

Thank you. I use the 18F67K22 and I have to emulate a PWM with a base frequency of 20 HZ. Thanks again

No problem.
Are you using internal or external osc and at what frequency?
If you are not fussed, then I created a quick example with internal OSC at 16MHz
It may be best to complete a
1sec flasher test to make sure chip is running at the correct osc speed.

I used ext osc. a 16 MHz PLL active a 4X ( 64MHz ).
To day i try your example

Medelec but what version do you have of FC8? tells me you have compiled it with a newer version of 8.1 ... and that may not work!

Hi
I'm running 8.2.0.12 in which patch was downloaded from
here
What I do every so often is while I have a flowchart open, Select
Help,
Check for updates.
Change
Files in-use to
Full database
So long as you are running 8.2 there will be no issues with not working due to version differences
