Light modification of Michele Gazzarri's library Some syntaxis corrections. Moved out output functions from library. Moved out every stuff about certain STM32 MCU. Tested on MOD-IR-TEMP board from Olimex and NUCLEO-F303RE from STMicroelectronics. Code related to MCU generated using STM32CubeIDE (and STM32CubeMX). Only main.c modified.
