Input programming activity

The previous activities showed you how to make the microcontroller activate outputs. This activity demonstrates how to receive inputs from externally connected devices. The input programs also introduce the concept of abstraction—the ability of a program to refer to I/O circuits using assigned variable names rather than their specific hardware addresses. What you should know […]

PIC Programmer and Programming

Programmer There are many PIC programmers you can purchase or whose schematics (and software) you can find freely over the Internet David Tait has a programmer with software and hardware schematics available here. If you read his documentation, you will find various programmer schematics. I use the Classic “Tait” Programmer. The schematic is below: I
