Can a PIC microcontroller generate a PWM wave?

Can a PIC microcontroller generate a PWM wave?

PWM waves can be easily generated using CCP modules available with most of the PIC Microcontrollers. CCP stands for Capture / Compare / PWM, which means that it can be used for Capture or Compare or PWM operations.

How is SPWM used in pic16f684 transformer?

The 16F684 generates SPWM signals on P1A, P1B, P1C and P1D pins which should then be connected to a full-bridge stage for feeding into transformer. 16kHz frequency is used since it is toward the end of the audible spectrum and so the noise emitted will not be intolerable.

What are the CCP modules of the Microchip PIC 16f877a?

Microchip’s PIC 16F877A microcontroller has two CCP modules, named as CCP1 and CCP2. Each CCP module comprises of two 8 bit registers which can be operate as :

How are LEDs used to demonstrate the working of PWM?

This circuit can be used to demonstrate the working of PWM. An LED is connected to the output of each CCP module through a series resistor to limit the current. Push Button Switches are used to adjust the PWM duty of both channels. We can see that the light intensity of LED increases as the PWM duty increases.
