Can the PIC12F675 drive motors directly from its GPIO pins?

As I mentioned in my previous post, my project student Kevin Chubb is developing tiny ultra low cost robots using a PIC12F microcontroller. One of the things that’s great about PICs is that they can source and sink relatively high … Continue reading

dsPIC30F Quadrature Encoder Interface (QEI) – Basic Example

This video shows a basic example of using the Quadrature Encoder Interface (QEI) on Microchip’s dsPIC30F4011 microcontroller. I expect that the same approach will work with other microcontrollers in the dsPIC30F family. In this example, I place two TCRT5000 reflective … Continue reading
