[SOLVED] PWM not working with MikroC Pro for PIC

[jsbhalla88]

Hello guys
I am using PIC18F45K22, coding using MikroC Pro for PIC, and trying to use PWM library functions.
if I use PWM1 functions, I am able to get PWM working on pin RC2...
but I am not able to get RC1 PWM working. I have tried PWM1/2/3/4/5 all functions....

What could be the problem??

ALSO,
I am able to enter a variable duty cycle, but not variable frequency in these PWM functions.
How to do this?? it gives an error that it should be a constant...is it possible or not.?

can you post your code??

I'm not recomend you to use such libraries at all. Open datasheet, find correcponding topic and write correct values to register according manual. This libraries is a "black boxes" with unexpected results. Never know, what to expect from them.

Not sure, but the PIC18F45K22 could be one of those devices where you have to set in the config bits whether a ccp pin (in your case, RC1) should be assigned to ccp (pwm operation). Maybe you can check the project options? And yes, I remember seeing in the help/documentation of MikroC's PWM libraries that you can't use variables (only constant values) for defining the frequency using their functions.
