| * @brief IRDA HAL module driver. |
| * This file provides firmware functions to manage the following |
| * functionalities of the IrDA SIR ENDEC block (IrDA): |
| * + Initialization and de-initialization functions |
| * + IO operation functions |
| * + Peripheral Control functions |
| * + Peripheral State and Errors functions |
| @verbatim |
| ============================================================================== |
| ##### How to use this driver ##### |
| ============================================================================== |
| [..] |
| The IRDA HAL driver can be used as follows: |
| |
| (#) Declare a IRDA_HandleTypeDef handle structure (eg. IRDA_HandleTypeDef hirda). |
| (#) 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 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 stream. |
| (+++) Enable the DMAx interface clock. |
| (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters. |
| (+++) Configure the DMA Tx/Rx stream. |
| (+++) Associate the initialized 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 stream. |
| (+++) Configure the IRDAx interrupt priority and enable the NVIC USART IRQ handle |
| (used for last byte sending completion detection in DMA non circular mode) |
| |
| (#) 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 customized 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() |

| (+) Stop the DMA Transfer using HAL_IRDA_DMAStop() |
| |
| *** 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 : Check whether the specified IRDA flag is set or not |
| (+) __HAL_IRDA_CLEAR_FLAG : Clear the specified IRDA pending flag |
| (+) __HAL_IRDA_ENABLE_IT: Enable the specified IRDA interrupt |
| (+) __HAL_IRDA_DISABLE_IT: Disable the specified IRDA interrupt |
| (+) __HAL_IRDA_GET_IT_SOURCE: Check whether the specified IRDA interrupt has occurred or not |
| |
| [..] |
| (@) You can refer to the IRDA HAL driver header file for more useful macros |
| |
| ##### Callback registration ##### |
| ================================== |
| |
| [..] |
| The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS when set to 1 |
| allows the user to configure dynamically the driver callbacks. |
| |
| [..] |
| Use Function @ref HAL_IRDA_RegisterCallback() to register a user callback. |
| Function @ref HAL_IRDA_RegisterCallback() allows to register following callbacks: |
| (+) TxHalfCpltCallback : Tx Half Complete Callback. |
| (+) TxCpltCallback : Tx Complete Callback. |
| (+) RxHalfCpltCallback : Rx Half Complete Callback. |
| (+) RxCpltCallback : Rx Complete Callback. |
| (+) ErrorCallback : Error Callback. |
| (+) AbortCpltCallback : Abort Complete Callback. |
| (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. |
| (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. |
| (+) MspInitCallback : IRDA MspInit. |
| (+) MspDeInitCallback : IRDA MspDeInit. |
| This function takes as parameters the HAL peripheral handle, the Callback ID |
| and a pointer to the user callback function. |
| |
| [..] |
| Use function @ref HAL_IRDA_UnRegisterCallback() to reset a callback to the default |
| weak (surcharged) function. |
| @ref HAL_IRDA_UnRegisterCallback() takes as parameters the HAL peripheral handle, |
| and the Callback ID. |
| This function allows to reset following callbacks: |
| (+) TxHalfCpltCallback : Tx Half Complete Callback. |
| (+) TxCpltCallback : Tx Complete Callback. |
| (+) RxHalfCpltCallback : Rx Half Complete Callback. |
| (+) RxCpltCallback : Rx Complete Callback. |
| (+) ErrorCallback : Error Callback. |
| (+) AbortCpltCallback : Abort Complete Callback. |
| (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. |
| (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. |
| (+) MspInitCallback : IRDA MspInit. |
| (+) MspDeInitCallback : IRDA MspDeInit. |
| |
| [..] |
| By default, after the @ref HAL_IRDA_Init() and when the state is HAL_IRDA_STATE_RESET |
| all callbacks are set to the corresponding weak (surcharged) functions: |
| examples @ref HAL_IRDA_TxCpltCallback(), @ref HAL_IRDA_RxHalfCpltCallback(). |
| Exception done for MspInit and MspDeInit functions that are respectively |
| reset to the legacy weak (surcharged) functions in the @ref HAL_IRDA_Init() |
| and @ref HAL_IRDA_DeInit() only when these callbacks are null (not registered beforehand). |
| If not, MspInit or MspDeInit are not null, the @ref HAL_IRDA_Init() and @ref HAL_IRDA_DeInit() |
| keep and use the user MspInit/MspDeInit callbacks (registered beforehand). |
| |
| [..] |
| Callbacks can be registered/unregistered in HAL_IRDA_STATE_READY state only. |
| Exception done MspInit/MspDeInit that can be registered/unregistered |
| in HAL_IRDA_STATE_READY or HAL_IRDA_STATE_RESET state, thus registered (user) |
| MspInit/DeInit callbacks can be used during the Init/DeInit. |
| In that case first register the MspInit/MspDeInit user callbacks |
| using @ref HAL_IRDA_RegisterCallback() before calling @ref HAL_IRDA_DeInit() |
| or @ref HAL_IRDA_Init() function. |
| |
| [..] |
| When The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS is set to 0 or |
| not defined, the callback registration feature is not available |
| and weak (surcharged) callbacks are used. |
| |

| [..] |
| (@) Additionnal remark: 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), |
| the possible IRDA frame formats are as listed in the following table: |
| +-------------------------------------------------------------+ |
| | M bit | PCE bit | IRDA frame | |
| |---------------------|---------------------------------------| |
| | 0 | 0 | | SB | 8 bit data | 1 STB | | |
| |---------|-----------|---------------------------------------| |
| | 0 | 1 | | SB | 7 bit data | PB | 1 STB | | |
| |---------|-----------|---------------------------------------| |
| | 1 | 0 | | SB | 9 bit data | 1 STB | | |
| |---------|-----------|---------------------------------------| |
| | 1 | 1 | | SB | 8 bit data | PB | 1 STB | | |
| +-------------------------------------------------------------+ |

| ##### Initialization and Configuration functions ##### |
| ============================================================================== |
| [..] |
| This subsection provides a set of functions allowing to initialize the USARTx or the UARTy |
| in asynchronous IrDA mode. |
| (+) For the asynchronous mode only these parameters can be configured: |
| (++) BaudRate |
| (++) WordLength |
| (++) 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), |
| please refer to Reference manual for possible IRDA frame formats. |
| (++) Prescaler: A pulse of width less than two and greater than one PSC period(s) may or may |
| not be rejected. The receiver set up time should be managed by software. The IrDA physical layer |
| specification specifies a minimum of 10 ms delay between transmission and |
| reception (IrDA is a half duplex protocol). |
| (++) Mode: Receiver/transmitter modes |
| (++) IrDAMode: the IrDA can operate in the Normal mode or in the Low power mode. |
| [..] |
| The HAL_IRDA_Init() API follows IRDA configuration procedures (details for the procedures |
| are available in reference manual). |

| @verbatim |
| ============================================================================== |
| ##### IO operation functions ##### |
| ============================================================================== |
| [..] |
| This subsection provides a set of functions allowing to manage the IRDA data transfers. |
| IrDA is a half duplex communication protocol. If the Transmitter is busy, any data |
| on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver |
| is busy, data on the TX from the USART to IrDA will not be encoded by IrDA. |
| While receiving data, transmission should be avoided as the data to be transmitted |
| could be corrupted. |
| |
| (#) There are two modes of transfer: |
| (++) 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. |
| (++) Non-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 respectively at the end of the Transmit or Receive process |
| The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected |
| |
| (#) Blocking mode APIs are : |
| (++) HAL_IRDA_Transmit() |
| (++) HAL_IRDA_Receive() |
| |
| (#) Non Blocking mode APIs with Interrupt are : |
| (++) HAL_IRDA_Transmit_IT() |
| (++) HAL_IRDA_Receive_IT() |
| (++) HAL_IRDA_IRQHandler() |
| |
| (#) Non Blocking mode functions with DMA are : |
| (++) HAL_IRDA_Transmit_DMA() |
| (++) HAL_IRDA_Receive_DMA() |
| (++) HAL_IRDA_DMAPause() |
| (++) HAL_IRDA_DMAResume() |
| (++) HAL_IRDA_DMAStop() |
| |
| (#) A set of Transfer Complete Callbacks are provided in Non Blocking mode: |
| (++) HAL_IRDA_TxHalfCpltCallback() |
| (++) HAL_IRDA_TxCpltCallback() |
| (++) HAL_IRDA_RxHalfCpltCallback() |
| (++) HAL_IRDA_RxCpltCallback() |
| (++) HAL_IRDA_ErrorCallback() |
| |
| (#) Non-Blocking mode transfers could be aborted using Abort API's : |
| (+) HAL_IRDA_Abort() |
| (+) HAL_IRDA_AbortTransmit() |
| (+) HAL_IRDA_AbortReceive() |
| (+) HAL_IRDA_Abort_IT() |
| (+) HAL_IRDA_AbortTransmit_IT() |
| (+) HAL_IRDA_AbortReceive_IT() |
| |
| (#) For Abort services based on interrupts (HAL_IRDA_Abortxxx_IT), a set of Abort Complete Callbacks are provided: |
| (+) HAL_IRDA_AbortCpltCallback() |
| (+) HAL_IRDA_AbortTransmitCpltCallback() |
| (+) HAL_IRDA_AbortReceiveCpltCallback() |
| |
| (#) In Non-Blocking mode transfers, possible errors are split into 2 categories. |
| Errors are handled as follows : |
| (+) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is |
| to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception . |
| Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type, |
| and HAL_IRDA_ErrorCallback() user callback is executed. Transfer is kept ongoing on IRDA side. |
| If user wants to abort it, Abort services should be called by user. |
| (+) Error is considered as Blocking : Transfer could not be completed properly and is aborted. |
| This concerns Overrun Error In Interrupt mode reception and all errors in DMA mode. |
| Error code is set to allow user to identify error type, and HAL_IRDA_ErrorCallback() user callback is executed. |
