| mbed_official | 330:c80ac197fa6a | 19 | =============================================================================== |

| mbed_official | 330:c80ac197fa6a | 21 | The USART HAL driver can be used as follows: |
| mbed_official | 330:c80ac197fa6a | 22 | |
| mbed_official | 330:c80ac197fa6a | 23 | (#) Declare a USART_HandleTypeDef handle structure. |
| mbed_official | 330:c80ac197fa6a | 24 | (#) Initialize the USART low level resources by implement the HAL_USART_MspInit ()API: |
| mbed_official | 330:c80ac197fa6a | 25 | (##) Enable the USARTx interface clock. |
| mbed_official | 330:c80ac197fa6a | 26 | (##) USART pins configuration: |
| mbed_official | 330:c80ac197fa6a | 27 | (+) Enable the clock for the USART GPIOs. |
| mbed_official | 330:c80ac197fa6a | 28 | (+) Configure these USART pins as alternate function pull-up. |
| mbed_official | 330:c80ac197fa6a | 29 | (##) NVIC configuration if you need to use interrupt process (HAL_USART_Transmit_IT(), |
| mbed_official | 330:c80ac197fa6a | 30 | HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs): |
| mbed_official | 330:c80ac197fa6a | 31 | (+) Configure the USARTx interrupt priority. |
| mbed_official | 330:c80ac197fa6a | 32 | (+) Enable the NVIC USART IRQ handle. |
| mbed_official | 330:c80ac197fa6a | 33 | (@) The specific USART interrupts (Transmission complete interrupt, |
| mbed_official | 330:c80ac197fa6a | 34 | RXNE interrupt and Error Interrupts) will be managed using the macros |
| mbed_official | 330:c80ac197fa6a | 35 | __HAL_USART_ENABLE_IT() and __HAL_USART_DISABLE_IT() inside the transmit and receive process. |
| mbed_official | 330:c80ac197fa6a | 36 | (##) DMA Configuration if you need to use DMA process (HAL_USART_Transmit_DMA() |
| mbed_official | 330:c80ac197fa6a | 37 | HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs): |
| mbed_official | 330:c80ac197fa6a | 38 | (+) Declare a DMA handle structure for the Tx/Rx channel. |
| mbed_official | 330:c80ac197fa6a | 39 | (+) Enable the DMAx interface clock. |
| mbed_official | 330:c80ac197fa6a | 40 | (+) Configure the declared DMA handle structure with the required Tx/Rx parameters. |
| mbed_official | 330:c80ac197fa6a | 41 | (+) Configure the DMA Tx/Rx channel. |
| mbed_official | 330:c80ac197fa6a | 42 | (+) Associate the initilalized DMA handle to the USART DMA Tx/Rx handle. |
| mbed_official | 330:c80ac197fa6a | 43 | (+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel. |
| mbed_official | 330:c80ac197fa6a | 44 | |
| mbed_official | 330:c80ac197fa6a | 45 | (#) Program the Baud Rate, Word Length , Stop Bit, Parity, Hardware |
| mbed_official | 330:c80ac197fa6a | 46 | flow control and Mode(Receiver/Transmitter) in the husart Init structure. |
| mbed_official | 330:c80ac197fa6a | 47 | |
| mbed_official | 330:c80ac197fa6a | 48 | (#) Initialize the USART registers by calling the HAL_USART_Init() API: |
| mbed_official | 330:c80ac197fa6a | 49 | (+) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc) |
| mbed_official | 330:c80ac197fa6a | 50 | by calling the customed HAL_USART_MspInit(&husart) API. |
