Hi all, I've just about completed one a series (I hope) of code modules for ROMzap. It should be a simple matter of selecting the code module, upload it and go. This one is a voltmeter which supports logging and a few other bits and pieces. Here is a gif of the meter screen and one method of displaying the data graph. http://www.picnpoke.com/demo/images/meter.gif -- Best regards Tony http://www.picnpoke.com mailto:sales@picnpoke.com
