"PIC17Dev" Project

This was an amazing project for me simply because just about everything went right; the circuit that I designed and demonstrated in Introduction to Electronics was basically correct the first time I ran it and I was able to write and debug the application code in one day. This application is an excellent introduction to the PIC17CXXX and one that you can use as the basis of a prototyping tool or as an emulator. I recommend that if you are going to build this application that you use the PCB information contained on the CD-ROM.

Click Here to look at the PICmicro® MCU code written for the application.

The circuit used for this application is in pdf format and can be seen Here.

The bill of materials for the circuit is listed in the table below.
