Not long ago we published an article about using an Arduino UNO as a logic analyzer. As it couldn´t be otherwise, you can also do the same with a Papilio. And guess what? The Papilio-based logic analyzer is more powerful. No hype, just real numbers. You can achieve 32 channels, at 200 MHz, while you can only get up to 4 MHz with the Arduino UNO.
Fine, we have to admit that there might be a minor drawback. Papilio works with signals at 3.3 V. Easy to solve, all you need to do is add a level translator and then you are ready to play with 5V signals as well!
Enjoy this great tutorial and have fun with your logic analyzer. Read the full article and you will know why you can make such a great logic analyzer from your Papilio!
