使用PWM

The PICmico™ family of RISC microcontrollers hax
been designed to provide advanced performance and a
cost-effective solution for a variety of applications. This
application note provides examples which illustrate
some uses of Pulse Width Modulation (PWM) using the
PIC17C42’s Timer1 or Timer2 module. These examples
may be modified to suit the specific needs of your appli-
cation.
