The PICmico? family of RISC microcontrollers has 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 application. This Application Note describes the operation of the
PWM. They include the following topics: 1. Simple PWM Operation 2. Variable Period / Variable Duty Cycle PWM 3. External Clock for Timer Time-base
(ramifications/issues) The listing file for the Variable Period / Variable Duty Cycle example can be found in Appendix A.The source files can be found on the Microchip BBS. On directions on how to access the Microchip BBS please refer to DS30128, which can also be found in the Microchip
Embedded Control Handbook (Literature Number DS00092).
