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

Minimum Viable Program for PIC12LF1572
Kevin Chubb (currently a final-year project student here in DIT) is designing a tiny robot using Microchip’s compact PIC12LF1572 microcontroller. It’s an interesting chip and Kevin’s doing great things with it. I decided to strip back one of the example … 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
