As i said, the minimum frequency should be 1.2Khz. 1.3KHZ work fine here. So change it to...
About now?Code:-----[ LCD Contrast PWM ]----------------------------------------- PWM_Contrast: value=Contrast*40 HPwm 1,value,1300 Return ; -----[ LCD Backlight PWM ]---------------------------------------- PWM_BackLight: value=Backlight*51 HPwm 2,value,1300 Return

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

Of course, you are correct changing to 1300 worked. Which, now that I think about it, makes sense because I was using the internal 8mHz clock on the 16F88.
Thanks for the help, its my first time with PWM. Needless to say I will remember this in the future.
I may ask Melanie to make a note about this in here FAQ.

So my guess in the previous post #2 about SPBRG value was correct. You should modify it NOW!
And... the minimum frequency range is stated in the PBP manual... OUPS!
Glad to know it's working now.
Have fun!

I did the RTFM thing and saw the chart. I just didn't make the link mentally between the chart and my code. I will in the future.
Thanks!
