Independent pwm frequency, duty cycle and phaseshift changes. This page will help you to configure the pic timer2 and pwm modules, you will also get a readytouse c source code for mikroc compiler. C compiler activates the preprocessor which goes through the program in search for these signs. In this tutorial we will see how to generate the pwm signals using pic16f877a.
If any encountered, the preprocessor will simply replace them by another text which, depending on the type of. The average dc value of the signal can be varied by varying the duty cycle. The fraction of the period for which the signal is on is known as the duty cycle. Pic microcontrollers the basics of c programming language. In this tutorial we learn how to generate pwm signals using pic. Assuming css is really ccs, take a look at this link. Pic16f877a pwm example with ccs pic c compiler the microcontroller pic16f877a has two ccp modules and with these modules we can generate two pwm pulse width modulation signals pwm1 related with ccp1 and pwm2 related with ccp2. Two motors control using pic16f887 and l293d ccs c compiler the l293d quadruple halfh drivers chip allows us to drive 2 motors in both directions, and with the two pwm modules on the pic16f887 microcontroller we can easily control the rotation speed of the two motors. Pic microcontrollers, for beginners too online, author. Pulse width modulation pwm is a technique of controlling the amount of power delivered to an electronic load using an onoff digital signal. In this tutorial we will be discussing only the pwm part of ccp. In this tutorial we will see how to interface a 16x2 character lcd module with pic 16f877a microcontroller using ccs c compiler.
Pulse width modulation pwm using the ccs compiler its. Both pwm modules use timer2 to generate signals which means the two modules will have the same frequency. A tutorial for implementing pwm with the ccs compiler. Generating pwm with pic microcontroller mikroc pro electrosome. Msp430 timer pwm tutorial including basic operation and registers for the internal timer peripheral, as well as c code examples written in ccs. In this tutorial, i have created a c function that sets up the pwm frequency and duty cycle. You will learn how to configure and program in a pic microcontroller this important signal known as pwm. This section of the manual contains the following major topics. Two motors control using pic16f887 and l293d ccs c compiler.
