I already find a solution, as you say 18F1330 looks like the best model for PWM aplications. It have 18 pins and ADC, perfect for my project, but the microcode doesnt works with it as well as the other micros, when you try to use the HPWM, many errors occur..

I have been working on the project today, and finally it works, working directly with the registers, you can drive 3 different PWM at the time.

Lets see how the ADC works and if i can finish my project without any other problem.

Thankyou for all..
