Uart I2c

The document outlines a series of programming tasks related to UART communication and sensor data acquisition using an STM32 microcontroller. It includes functions for sending integers, strings, and floats via UART, reading temperature data from an LM35 sensor, and displaying text on an LCD screen based on input received from a keyboard. The code also includes initialization routines for various peripherals and a main loop for continuous operation.
