=============================================================================== ##### How to use this driver ##### =============================================================================== [..] The UART HAL driver can be used as follows: (#) Declare a UART_HandleTypeDef handle structure (eg. UART_HandleTypeDef huart). (#) Initialize the UART low level resources by implementing the HAL_UART_MspInit() API: (++) Enable the USARTx interface clock. (++) UART pins configuration: (+++) Enable the clock for the UART GPIOs. (+++) Configure these UART pins as alternate function pull-up. (++) NVIC configuration if you need to use interrupt process (HAL_UART_Transmit_IT() and HAL_UART_Receive_IT() APIs): (+++) Configure the USARTx interrupt priority. (+++) Enable the NVIC USART IRQ handle. (++) UART interrupts handling: -@@- The specific UART interrupts (Transmission complete interrupt, RXNE interrupt and Error Interrupts) are managed using the macros __HAL_UART_ENABLE_IT() and __HAL_UART_DISABLE_IT() inside the transmit and receive processes. (++) DMA Configuration if you need to use DMA process (HAL_UART_Transmit_DMA() and HAL_UART_Receive_DMA() APIs): (+++) Declare a DMA handle structure for the Tx/Rx channel. (+++) Enable the DMAx interface clock. (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters. (+++) Configure the DMA Tx/Rx channel. (+++) Associate the initialized DMA handle to the UART DMA Tx/Rx handle. (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel. (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware flow control and Mode (Receiver/Transmitter) in the huart handle Init structure. (#) If required, program UART advanced features (TX/RX pins swap, auto Baud rate detection,...) in the huart handle AdvancedInit structure. (#) For the UART asynchronous mode, initialize the UART registers by calling the HAL_UART_Init() API. (#) For the UART Half duplex mode, initialize the UART registers by calling the HAL_HalfDuplex_Init() API. (#) For the UART LIN (Local Interconnection Network) mode, initialize the UART registers by calling the HAL_LIN_Init() API. (#) For the UART Multiprocessor mode, initialize the UART registers by calling the HAL_MultiProcessor_Init() API. (#) For the UART RS485 Driver Enabled mode, initialize the UART registers by calling the HAL_RS485Ex_Init() API. [..] (@) These API's (HAL_UART_Init(), HAL_HalfDuplex_Init(), HAL_LIN_Init(), HAL_MultiProcessor_Init(), also configure the low level Hardware GPIO, CLOCK, CORTEX...etc) by calling the customized HAL_UART_MspInit() API.
