Hello, everybody.
I try make simple PWM using PIC18F26K22. I found in posts this: http://www.matrixtsl.com/mmforums/viewt ... pwm#p62906
Brendan posts answers, but I can't understand how tune PIC. I tried all the things I thought but I need a little nudge.
This PIC have true many, many settings. I want to use it because have lot of words and memory and I need of very simple PWM.
I will be happy if somebody loose 30 seconds for me. I'm sure for the experts this will be a toy, but it really hinders me.

Re: Question about PIC18F26K22 and PWM
Hello,
The only thing I have spotted is that in your configuration settings you have the Primary Clock Enable set to Disabled. Maybe this should be enabled.
Everything else seems to look ok.
Are you connecting the MCLR pin to VCC using say a 10K -100K resistor?
I would probably advise the one second flasher test to help double check the device is running as expected and at the right speed. Once this is correct the PWM should simply work.

Thanks, Benj for the answer. It's my mistake.
In my program I write duty=256 instead 255. I need glasses probably
