Hi
Pwm Channel3 (AVR MEGA8) works in software but does not work on the chip.
Please advise.

One of my friends answer me

Hello,

Sorry for the delay. I'm investigating for you now. I've now had a good check through the code and the device datasheet and it all looks ok.

As a test if you enable timer 2 interrupt does this allow the PWM to function?

Hello Benj
How to do it؟
Because I don't know anything about C Code.
Please guide me.

Hello,

Just add an interrupt icon, set the type to enable timer 2 and configure the prescaler and other properties as desired. Hopefully this should kick start the PWM but let me know how you get on.

Hello Benj
The method you provided didn't work.
The software makes an error when compiling.

Hello
Please advise.

Hello,

Sorry for the delay, I've now pushed updates to the update system to allow the timer2 interrupt to compile correctly. This gives me a clue as to the PWM issue too so I'll see if I can get this resolved too so you dont have to add the interrupt icon.
