| 15 | ##### How to use this driver #####
|
---|
| 16 | ===============================================================================
|
---|
| 17 | [..]
|
---|
| 18 | The SPDIFRX HAL driver can be used as follow:
|
---|
| 19 |
|
---|
| 20 | (#) Declare SPDIFRX_HandleTypeDef handle structure.
|
---|
| 21 | (#) Initialize the SPDIFRX low level resources by implement the HAL_SPDIFRX_MspInit() API:
|
---|
| 22 | (##) Enable the SPDIFRX interface clock.
|
---|
| 23 | (##) SPDIFRX pins configuration:
|
---|
| 24 | (+++) Enable the clock for the SPDIFRX GPIOs.
|
---|
| 25 | (+++) Configure these SPDIFRX pins as alternate function pull-up.
|
---|
| 26 | (##) NVIC configuration if you need to use interrupt process (HAL_SPDIFRX_ReceiveControlFlow_IT() and HAL_SPDIFRX_ReceiveDataFlow_IT() API's).
|
---|
| 27 | (+++) Configure the SPDIFRX interrupt priority.
|
---|
| 28 | (+++) Enable the NVIC SPDIFRX IRQ handle.
|
---|
| 29 | (##) DMA Configuration if you need to use DMA process (HAL_SPDIFRX_ReceiveDataFlow_DMA() and HAL_SPDIFRX_ReceiveControlFlow_DMA() API's).
|
---|
| 30 | (+++) Declare a DMA handle structure for the reception of the Data Flow channel.
|
---|
| 31 | (+++) Declare a DMA handle structure for the reception of the Control Flow channel.
|
---|
| 32 | (+++) Enable the DMAx interface clock.
|
---|
| 33 | (+++) Configure the declared DMA handle structure CtrlRx/DataRx with the required parameters.
|
---|
| 34 | (+++) Configure the DMA Channel.
|
---|
| 35 | (+++) Associate the initialized DMA handle to the SPDIFRX DMA CtrlRx/DataRx handle.
|
---|
| 36 | (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the
|
---|
| 37 | DMA CtrlRx/DataRx channel.
|
---|
| 38 |
|
---|
| 39 | (#) Program the input selection, re-tries number, wait for activity, channel status selection, data format, stereo mode and masking of user bits
|
---|
| 40 | using HAL_SPDIFRX_Init() function.
|
---|
| 41 |
|
---|
| 42 | -@- The specific SPDIFRX interrupts (RXNE/CSRNE and Error Interrupts) will be managed using the macros
|
---|
| 43 | __SPDIFRX_ENABLE_IT() and __SPDIFRX_DISABLE_IT() inside the receive process.
|
---|
| 44 | -@- Make sure that ck_spdif clock is configured.
|
---|
| 45 |
|
---|

|
---|
| 393 | (++) Blocking mode : The communication is performed in the polling mode.
|
---|
| 394 | The status of all data processing is returned by the same function
|
---|
| 395 | after finishing transfer.
|
---|
| 396 | (++) No-Blocking mode : The communication is performed using Interrupts
|
---|
| 397 | or DMA. These functions return the status of the transfer start-up.
|
---|
| 398 | The end of the data processing will be indicated through the
|
---|
| 399 | dedicated SPDIFRX IRQ when using Interrupt mode or the DMA IRQ when
|
---|
| 400 | using DMA mode.
|
---|

| 404 | (++) HAL_SPDIFRX_ReceiveControlFlow()
|
---|
| 405 | (+@) Do not use blocking mode to receive both control and data flow at the same time.
|
---|
| 406 |
|
---|
| 407 | (#) No-Blocking mode functions with Interrupt are :
|
---|
| 408 | (++) HAL_SPDIFRX_ReceiveControlFlow_IT()
