This is a prototype of the Arduino Automated Test Tool.

This tool can be used to test software applications on micro-controllers and it allows to create python scripts which interact with Arduino via serial communication and simulate the inputs for the microcontroller and gets the outputs.

Currently, only the functions to test applications that use GPIO as digital input/output are ready to use.

Functions to test drivers for communication protocols such SPI, I2C, UART, etc, and other testing capabilities are considered to be developed in the future.

The folder where the scripts are stored is "scripts", there is already an example to test an application that runs on a STM32 micro-controller.

MCU settings considerations.

For STM32 micro-controllers:

For the test example, the outputs of Arduino are configured with the internal pull_up resistors enabled. That means if we have the GPIO pin Arduino connected to nothing(floating) reads it as High and when we put the pin to ground it is read as Low. This configuration allows connecting the Arduino inputs directly to the SMT32 outputs. Therefore, the STM32 outputs must have the open-drain configuration (High - floating, Low - ground).
