Logic Analyzer

Logic Analyzer helps you to debug your circuits in a easy and cheap way.
It acquires up to 8 digital signals and shows it on the screen of your iOS device.
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.
It's based on ESP32 / Arduino Mega and data are transferred from Arduino to the iPhone or iPad via Bluetooth BLE. This allows you to make measurements on devices which are far from you.
To make it working, you need:
1) ESP32 or Arduino Mega
2) Adafruit Bluefruit LE - nRF8001 Breakout / Shield (required for Arduino Mega only)
3) A measurement sketch that you can download from my site for free
