- * @brief IRDA HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the IrDA (Infrared Data Association) Peripheral
- * (IRDA)
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral Control functions
- *
- *
- @verbatim
- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- The IRDA HAL driver can be used as follows:
-
-
- (#) Declare a IRDA_HandleTypeDef handle structure.
- (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API:
- (##) Enable the USARTx interface clock.
- (##) IRDA pins configuration:
- (+) Enable the clock for the IRDA GPIOs.
- (+) Configure these IRDA pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
- and HAL_IRDA_Receive_IT() APIs):
- (+) Configure the USARTx interrupt priority.
- (+) Enable the NVIC USART IRQ handle.
- (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
- and HAL_IRDA_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 initilalized DMA handle to the IRDA 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, Parity, IrDA Mode, Prescaler
- and Mode(Receiver/Transmitter) in the hirda Init structure.
-
- (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
- (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customed HAL_IRDA_MspInit() API.
- -@@- The specific IRDA interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
-
- (#) Three operation modes are available within this driver :
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Send an amount of data in blocking mode using HAL_IRDA_Transmit()
- (+) Receive an amount of data in blocking mode using HAL_IRDA_Receive()
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Send an amount of data in non blocking mode using HAL_IRDA_Transmit_IT()
- (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_TxCpltCallback
- (+) Receive an amount of data in non blocking mode using HAL_IRDA_Receive_IT()
- (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_RxCpltCallback
- (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_IRDA_ErrorCallback
-
- *** DMA mode IO operation ***
- =============================
- [..]
- (+) Send an amount of data in non blocking mode (DMA) using HAL_IRDA_Transmit_DMA()
- (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_TxCpltCallback
- (+) Receive an amount of data in non blocking mode (DMA) using HAL_IRDA_Receive_DMA()
- (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_RxCpltCallback
- (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_IRDA_ErrorCallback
-
- *** IRDA HAL driver macros list ***
- ===================================
- [..]
- Below the list of most used macros in IRDA HAL driver.
-
- (+) __HAL_IRDA_ENABLE: Enable the IRDA peripheral
- (+) __HAL_IRDA_DISABLE: Disable the IRDA peripheral
- (+) __HAL_IRDA_GET_FLAG : Checks whether the specified IRDA flag is set or not
- (+) __HAL_IRDA_CLEAR_FLAG : Clears the specified IRDA pending flag
- (+) __HAL_IRDA_ENABLE_IT: Enables the specified IRDA interrupt
- (+) __HAL_IRDA_DISABLE_IT: Disables the specified IRDA interrupt
-
- (@) You can refer to the IRDA HAL driver header file for more useful macros

- ##### Initialization and Configuration functions #####
- ===============================================================================
- [..]
- This subsection provides a set of functions allowing to initialize the USARTx
- in asynchronous IRDA mode.
- (+) For the asynchronous mode only these parameters can be configured:
- (++) Baud Rate
- (++) Word Length
- (++) Parity: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- Depending on the frame length defined by the M bit (8-bits or 9-bits)
- or by the M1 and M0 bits (7-bit, 8-bit or 9-bit),
- the possible IRDA frame formats are as listed in the following table:
- +---------------------------------------------------------------+
- | M1M0 bits | PCE bit | IRDA frame |
- |-----------|-----------|---------------------------------------|
- | 00 | 0 | | SB | 8-bit data | STB | |
- |-----------|-----------|---------------------------------------|
- | 00 | 1 | | SB | 7-bit data | PB | STB | |
- |-----------|-----------|---------------------------------------|
- | 01 | 0 | | SB | 9-bit data | STB | |
- |-----------|-----------|---------------------------------------|
- | 01 | 1 | | SB | 8-bit data | PB | STB | |
- |-----------------------|---------------------------------------|
- | 10 | 0 | | SB | 7-bit data | STB | |
- |-----------|-----------|---------------------------------------|
- | 10 | 1 | | SB | 6-bit data | PB | STB | |
- +---------------------------------------------------------------+
-
- (++) Power mode
- (++) Prescaler setting
- (++) Receiver/transmitter modes
-
- [..]
- The HAL_IRDA_Init() API follows the USART asynchronous configuration procedures
- (details for the procedures are available in reference manual).

- This subsection provides a set of functions allowing to manage the IRDA asynchronous
- data transfers.

- (++) Blocking mode: the communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (++) No-Blocking mode: the communication is performed using Interrupts
- or DMA, these API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
- will be executed respectivelly at the end of the Transmit or Receive process
- The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected
