47.2 UART Firmware driver API description
47.2.1 How to use this driver
The UART HAL driver can be used as follows:
1. Declare a UART_HandleTypeDef handle structure.
2. Initialize the UART low level resources by implementing the HAL_UART_MspInit()
API:
a. Enable the USARTx interface clock.
b. UART pins configuration:
Enable the clock for the UART GPIOs.
