Logic Analyzer at Mac App Store analyse

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 decoders for the most used protocols (Serial, SPI and I2C) which will show characters directly over the signal.

Its 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 or ESP32
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
