The PWM Library Example demonstrates the use of the pulse-width modulation library by generating waveforms over a GPIO. The GPIO pin could drive a small speaker, for example.
This example generates two variable duty cycle pulses using two PWM channels (with positive and negative polarity). The duty cycle is changed automatically and will vary between 0 and 100.
The application uses the duty cycle pulses to drive LED 1 and LED 2. With a higher value, the light intensity of one of the LEDs increases, while the intensity of the other LED decreases.
