dsPIC30F Digital Inputs / Outputs

Using the digital input pins on a PIC microcontroller is fairly simple. There are, however, two different ways of wiring a switch (or any other switch-like device) to the pin — using a pull-up resistor, or a pull-down resistor. The schematic o...

dsPIC30F Motor Control PWM Module

Pulse Width Modulation, commonly referred to as PWM, is a common technique used for supplying power and motor control. Using it to power an LED, for example, means that by varying the duty cycle (which affects the average voltage) you can adjust the br...
