I'm very new to microcontrollers and I've been learning quite a bit by replicating others projects. My workbench is very sparse when it comes to test equipment though. I've come across http://pcsm1.u-strasbg.fr/liberlab/englishversion/ and was wondering if anyone could offer an opinion as to the soundness of the design. It's a few bucks in parts so I'll probably build in nonetheless. Would such a design provide accurate test data? Although I haven't abandoned ebay looking for a scope, this board has some of the features that I'm looking for. It looks like it is only able to handle positive voltage values. Could anyone point me in a direction to research expanding this capability?
I apologize if I missed some avrfreaks forum etiquette and have posted this in the wrong area. Thanks again for all of the interesting information you folks generously offer.
