STM32F446RE - I2C Master Testing

This repository host the firmware for NUCLEO F446RE board that utilizes STM32F446RE microcontroller to read data from an I2C slave.
This firmware is used to test the communication with the firmware on alwint3r/esp32-ultrasonic-i2c-slave.

How It Works

The STM32 device reads the distance measurement from the ESP32 device every 30 seconds and then print the result to the UART2 connected to the on-board ST-LINK.
