In this tutorial we will see how to generate the PWM signals on Explore M3.
Prerequisites
Please check this tutorial for detailed explanation on Lpc1768 PWM module.
If you are doing it for the first time, then check the below links to setup the project for generating the .bin file.
Explore M3 PWM Module
Explore M3 has 6 PWM output pins(24-29) which are mapped to internal PWM module as shown below.
| Explore M3 Pin | LPC1768 Pin | PWM Channel |
|---|---|---|
| 29 | P2.0 | PWM1[1] |
| 28 | P2.1 | PWM1[2] |
| 27 | P2.2 | PWM1[3] |
| 26 | P2.3 | PWM1[4] |
| 25 | P2.4 | PWM1[5] |
| 24 | P2.5 | PWM1[6] |
Code
Below is the example to vary the brightness of the LED using PWM.
