| 16 | ##### How to use this driver #####
|
---|
| 17 | ==============================================================================
|
---|
| 18 | [..]
|
---|
| 19 | The IRDA HAL driver can be used as follows:
|
---|
| 20 |
|
---|
| 21 | (#) Declare a IRDA_HandleTypeDef handle structure.
|
---|
| 22 | (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API:
|
---|
| 23 | (##) Enable the USARTx interface clock.
|
---|
| 24 | (##) IRDA pins configuration:
|
---|
| 25 | (+++) Enable the clock for the IRDA GPIOs.
|
---|
| 26 | (+++) Configure these IRDA pins as alternate function pull-up.
|
---|
| 27 | (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
|
---|
| 28 | and HAL_IRDA_Receive_IT() APIs):
|
---|
| 29 | (+++) Configure the USARTx interrupt priority.
|
---|
| 30 | (+++) Enable the NVIC USART IRQ handle.
|
---|
| 31 | (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
|
---|
| 32 | and HAL_IRDA_Receive_DMA() APIs):
|
---|
| 33 | (+++) Declare a DMA handle structure for the Tx/Rx stream.
|
---|
| 34 | (+++) Enable the DMAx interface clock.
|
---|
| 35 | (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
|
---|
| 36 | (+++) Configure the DMA Tx/Rx Stream.
|
---|
| 37 | (+++) Associate the initialized DMA handle to the IRDA DMA Tx/Rx handle.
|
---|
| 38 | (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
|
---|
| 39 |
|
---|
| 40 | (#) Program the Baud Rate, Word Length, Parity, IrDA Mode, Prescaler
|
---|
| 41 | and Mode(Receiver/Transmitter) in the hirda Init structure.
|
---|
| 42 |
|
---|
| 43 | (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
|
---|
| 44 | (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
|
---|
| 45 | by calling the customized HAL_IRDA_MspInit() API.
|
---|
| 46 | -@@- The specific IRDA interrupts (Transmission complete interrupt,
|
---|
| 47 | RXNE interrupt and Error Interrupts) will be managed using the macros
|
---|
| 48 | __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
|
---|
| 49 |
|
---|
| 50 | (#) Three operation modes are available within this driver :
|
---|
| 51 |
|
---|
| 52 | *** Polling mode IO operation ***
|
---|
| 53 | =================================
|
---|
| 54 | [..]
|
---|
| 55 | (+) Send an amount of data in blocking mode using HAL_IRDA_Transmit()
|
---|
| 56 | (+) Receive an amount of data in blocking mode using HAL_IRDA_Receive()
|
---|
| 57 |
|
---|
| 58 | *** Interrupt mode IO operation ***

|
---|
| 60 | [..]
|
---|
| 61 | (+) Send an amount of data in non blocking mode using HAL_IRDA_Transmit_IT()
|

---|
| 63 | add his own code by customization of function pointer HAL_IRDA_TxCpltCallback
|
---|
| 64 | (+) Receive an amount of data in non blocking mode using HAL_IRDA_Receive_IT()
|
---|
| 65 | (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can
|
---|
| 66 | add his own code by customization of function pointer HAL_IRDA_RxCpltCallback
|
---|
| 67 | (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can
|
---|
| 68 | add his own code by customization of function pointer HAL_IRDA_ErrorCallback
|
---|
| 69 |
|
---|
| 70 | *** DMA mode IO operation ***
|
---|
| 71 | =============================
|
---|
| 72 | [..]
|
---|
| 73 | (+) Send an amount of data in non blocking mode (DMA) using HAL_IRDA_Transmit_DMA()
|
---|
| 74 | (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can

| 183 | This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
|
---|
| 184 | in IrDA mode.
|
---|
| 185 | (+) For the asynchronous mode only these parameters can be configured:
|
---|
| 186 | (++) BaudRate
|
---|
| 187 | (++) WordLength
|
---|
| 188 | (++) Parity: If the parity is enabled, then the MSB bit of the data written
|
---|
| 189 | in the data register is transmitted but is changed by the parity bit.
|
---|
| 190 | Depending on the frame length defined by the M bit (8-bits or 9-bits),
|
---|
| 191 | please refer to Reference manual for possible IRDA frame formats.
|
---|
| 192 | (++) Prescaler: A pulse of width less than two and greater than one PSC period(s) may or may
|
---|
| 193 | not be rejected. The receiver set up time should be managed by software. The IrDA physical layer
|
---|
| 194 | specification specifies a minimum of 10 ms delay between transmission and
|
---|
| 195 | reception (IrDA is a half duplex protocol).
|
---|
| 196 | (++) Mode: Receiver/transmitter modes
|
---|
| 197 | (++) IrDAMode: the IrDA can operate in the Normal mode or in the Low power mode.
|
---|
| 198 | [..]
|
---|
| 199 | The HAL_IRDA_Init() API follows IRDA configuration procedures (details for the procedures
