Hi, I have two question with the use of the PWM....
The first one is, If I use PWM of 10 bit, because I do not have 1023, instead of 255?

And the second question is,Since it is possible to choose for example a frequency of 10khz?
.......regards

Hi,
1) You need to set the PWM property "Period Overflow" value to 1023 (this is only possible on target processors that support it)
2) The frequency will be calculated from the "Period Overflow" and the "Prescaler" values, and displayed. But you cannot set the frequency directly.
Hope that helps

Thank you very much for answering, Already I could have fitted the frequency to 10khz, But the rollover lowers 120,
the problem is for microprocessor of 8 bits...18f4620 I was thinking that on having chosen the pwm setdutyCycle10bits, Already it would work to 10 bits
PD: Again thank you very much for the help
