Velleman K8055 - [K8055 Software Tutorial]

K8055 Tutorial: Complete Example

A complete example program

As I wrote earlier this tutorial is not meant to teach you how to program. There are plenty of books or web sites for that. But I made one bigger example that shows you how you can read digital inputs, read/write digital outputs, read analog inputs and set digital outputs.

These are the functions in the program:

Allows to specify the jumper SK5/SK6
Button to toggle digital output 1
Button to set all channels
Button to clear all channels
Progressbar to indicate A/D channel 1
Progressbar to indicate A/D channel 2
Slider to change D/A output 1
Checkbox indication for the state of digital input #1 and #2

This demonstration project is written in Visual Basic Express 2010 (download the complete source code). I placed plenty of comments in the source code, so you can understand everything that is going on. The image below shows a fragment from the source code.
