NU32 Videos

This page has a number of videos supporting chapters in the book Embedded Computing and Mechatronics with the PIC32 Microcontroller. Sample code for the book used in these videos can be downloaded from the NU32 page. The sample code is for the PIC32MX795F512H as it is used on the NU32 development board.

Most of the videos below were created using the Lightboard, an ingenious and easy-to-use device developed by Prof. Michael Peshkin at Northwestern University. Our gratitude to Prof. Peshkin and Prof. Alex Birdwell, who runs the Lightboard Studio at Northwestern.
