Logic Analyzer helps you to debug your circuits in a simple and cheap way.

It acquires up to 8 digital signals and shows it on the screen of your MAC.

You can enable a trigger on one of the available channels to start reading signals when the channel goes up or down.

The app provides a Serial Decoder which will show characters directly over the signal.

It's based on Arduino Mega and data are transferred from Arduino to the MAC via USB or via Bluetooth BLE allowing you to make measurements also on devices which are far from you.

To make it working, you need:

1) Arduino Mega
2) A measurement sketch that you can download from my site for free
3) Adafruit Bluefruit LE - nRF8001 Breakout / Shield, if you use Bluetooth BLE
