##### 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
|
|
in setting the associated USART or UART in IRDA mode:
|
|
(++) Enable the USARTx/UARTx interface clock.
|
|
(++) USARTx/UARTx pins configuration:
|
|
(+++) Enable the clock for the USARTx/UARTx GPIOs.
|
|
(+++) Configure these USARTx/UARTx pins (TX as alternate function pull-up, RX as alternate function Input).
|
|
(++) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
|
|
and HAL_IRDA_Receive_IT() APIs):
|
|
(+++) Configure the USARTx/UARTx interrupt priority.
|
|
(+++) Enable the NVIC USARTx/UARTx IRQ handle.
|
|
(+++) 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.
|
|
|
|
(++) 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 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 channel.
|
|
|
|
(#) Program the Baud Rate, Word Length and Parity and Mode(Receiver/Transmitter),
|
|
the normal or low power mode and the clock prescaler in the hirda handle 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 :
|
|
|
|

|
|
===================================
|
|

|
|
[..]

|

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
|
|
(++) 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).

frame length is either defined by the M bit (8-bits or 9-bits)

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 mode 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_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.
