Tiny Scope for Arduino
Optimized for Teensy 3.1+ and Teensy LC Requires the pedvide ADC library from https://github.com/pedvide/ADC. Up to around 1.1Msps sampling speeds are possible with reduced precision.
Use v1.0.0 for other Arduino-compatible devices.
Voltmeter mode:
Uses standard Arduino code so it should work on other Arduino-compatible devices. Optimized for Atmega328 (direct ADC control for higher sampling speeds).
