Velleman K8000 - [K8000 Applications] - [K8000 from Excel]
One day , I was wondering if it was possible to define your own Excel functions, and use them to control the K8000. The answer was yes! This excel document demonstrates a little program where you have to enter the number 1 or 0 in a cell (D6). If you enter 1, the DAC1 channel will become high, else it will become low. This is done by a function in the cell F6, which calls the K8000 directly. This functions returns ON or OFF as value. Based on this application, you might make other applications. For example: read AD channels and monitor the temperature and set the results in a graph hourly.
