- Implemented USART2 initialization and interrupt handling. - Added a function to send data to the server via USART2. - Updated the main application to utilize USART2 for communication. - Changed system clock configuration to use HSE and PLL for higher frequency. - Adjusted SPI1 baud rate prescaler for improved performance. - Enhanced LED control logic based on RFID card detection. - Updated project configuration to reflect new USART2 settings.
