mbed_official 237:f3da66175598 20 ===============================================================================
mbed_official 237:f3da66175598 21 [..]
mbed_official 237:f3da66175598 22 The IRDA HAL driver can be used as follows:
mbed_official 237:f3da66175598 23
mbed_official 237:f3da66175598 24 (#) Declare a IRDA_HandleTypeDef handle structure.
mbed_official 237:f3da66175598 25 (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API
mbed_official 237:f3da66175598 26 in setting the associated USART or UART in IRDA mode:
mbed_official 237:f3da66175598 27 (##) Enable the USARTx/UARTx interface clock.
mbed_official 237:f3da66175598 28 (##) USARTx/UARTx pins configuration:
mbed_official 237:f3da66175598 29 (+) Enable the clock for the USARTx/UARTx GPIOs.
mbed_official 237:f3da66175598 30 (+) Configure these USARTx/UARTx pins as alternate function pull-up.
mbed_official 237:f3da66175598 31 (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
mbed_official 237:f3da66175598 32 and HAL_IRDA_Receive_IT() APIs):
mbed_official 237:f3da66175598 33 (+) Configure the USARTx/UARTx interrupt priority.
mbed_official 237:f3da66175598 34 (+) Enable the NVIC IRDA IRQ handle.
mbed_official 237:f3da66175598 35 (@) The specific IRDA interrupts (Transmission complete interrupt,
mbed_official 237:f3da66175598 36 RXNE interrupt and Error Interrupts) will be managed using the macros
mbed_official 237:f3da66175598 37 __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
mbed_official 237:f3da66175598 38 (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
mbed_official 237:f3da66175598 39 and HAL_IRDA_Receive_DMA() APIs):
mbed_official 237:f3da66175598 40 (+) Declare a DMA handle structure for the Tx/Rx stream.

mbed_official 237:f3da66175598 45 (+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
mbed_official 237:f3da66175598 46
mbed_official 237:f3da66175598 47 (#) Program the Baud Rate, Word Length and Parity and Mode(Receiver/Transmitter),

mbed_official 237:f3da66175598 51 the HAL_IRDA_Init() API.
