mbed_official | 631:825f75ca301e | 17 | ##### How to use this driver ##### |
mbed_official | 631:825f75ca301e | 18 | ============================================================================== |
mbed_official | 340:28d1f895c6fe | 19 | [..] |
mbed_official | 631:825f75ca301e | 20 | The SPI HAL driver can be used as follows: |
mbed_official | 631:825f75ca301e | 21 | |
mbed_official | 631:825f75ca301e | 22 | (#) Declare a SPI_HandleTypeDef handle structure, for example: |
mbed_official | 631:825f75ca301e | 23 | SPI_HandleTypeDef hspi; |
mbed_official | 631:825f75ca301e | 24 | |
mbed_official | 631:825f75ca301e | 25 | (#)Initialize the SPI low level resources by implementing the HAL_SPI_MspInit() API: |
mbed_official | 631:825f75ca301e | 26 | (##) Enable the SPIx interface clock |
mbed_official | 631:825f75ca301e | 27 | (##) SPI pins configuration |
mbed_official | 631:825f75ca301e | 28 | (+++) Enable the clock for the SPI GPIOs |
mbed_official | 631:825f75ca301e | 29 | (+++) Configure these SPI pins as alternate function push-pull |
mbed_official | 631:825f75ca301e | 30 | (##) NVIC configuration if you need to use interrupt process |
mbed_official | 631:825f75ca301e | 31 | (+++) Configure the SPIx interrupt priority |
mbed_official | 631:825f75ca301e | 32 | (+++) Enable the NVIC SPI IRQ handle |
mbed_official | 631:825f75ca301e | 33 | (##) DMA Configuration if you need to use DMA process |
mbed_official | 631:825f75ca301e | 34 | (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive channel |
mbed_official | 631:825f75ca301e | 35 | (+++) Enable the DMAx clock |
mbed_official | 631:825f75ca301e | 36 | (+++) Configure the DMA handle parameters |
mbed_official | 631:825f75ca301e | 37 | (+++) Configure the DMA Tx or Rx channel |
mbed_official | 631:825f75ca301e | 38 | (+++) Associate the initialized hdma_tx handle to the hspi DMA Tx or Rx handle |
mbed_official | 631:825f75ca301e | 39 | (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx channel |
mbed_official | 631:825f75ca301e | 40 | |
mbed_official | 631:825f75ca301e | 41 | (#) Program the Mode, BidirectionalMode , Data size, Baudrate Prescaler, NSS |
mbed_official | 631:825f75ca301e | 42 | management, Clock polarity and phase, FirstBit and CRC configuration in the hspi Init structure. |
mbed_official | 631:825f75ca301e | 43 | |
mbed_official | 631:825f75ca301e | 44 | (#) Initialize the SPI registers by calling the HAL_SPI_Init() API: |
mbed_official | 631:825f75ca301e | 45 | (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc) |
mbed_official | 631:825f75ca301e | 46 | by calling the customized HAL_SPI_MspInit() API. |
mbed_official | 631:825f75ca301e | 47 | [..] |
mbed_official | 631:825f75ca301e | 48 | Circular mode restriction: |
mbed_official | 631:825f75ca301e | 49 | (#) The DMA circular mode cannot be used when the SPI is configured in these modes: |
mbed_official | 631:825f75ca301e | 50 | (##) Master 2Lines RxOnly |
mbed_official | 631:825f75ca301e | 51 | (##) Master 1Line Rx |
mbed_official | 631:825f75ca301e | 52 | (#) The CRC feature is not managed when the DMA circular mode is enabled |
mbed_official | 631:825f75ca301e | 53 | (#) When the SPI DMA Pause/Stop features are used, we must use the following APIs |
mbed_official | 631:825f75ca301e | 54 | the HAL_SPI_DMAPause()/ HAL_SPI_DMAStop() only under the SPI callbacks |
mbed_official | 631:825f75ca301e | 55 | [..] |
mbed_official | 631:825f75ca301e | 56 | Using the HAL it is not possible to reach all supported SPI frequency with the differents |
mbed_official | 631:825f75ca301e | 57 | the following table resume the max SPI frequency reached with data size 8bits/16bits, |
mbed_official | 631:825f75ca301e | 58 | according to frequency used on APBx Peripheral Clock (fPCLK) used by the SPI instance : |

mbed_official | 631:825f75ca301e | 401 | [..] The SPI supports master and slave mode : |
mbed_official | 340:28d1f895c6fe | 402 | |
mbed_official | 340:28d1f895c6fe | 403 | (#) There are two modes of transfer: |
mbed_official | 631:825f75ca301e | 404 | (++) Blocking mode: The communication is performed in polling mode. |
mbed_official | 631:825f75ca301e | 405 | The HAL status of all data processing is returned by the same function |
mbed_official | 631:825f75ca301e | 406 | after finishing transfer. |
mbed_official | 631:825f75ca301e | 407 | (++) No-Blocking mode: The communication is performed using Interrupts |
mbed_official | 631:825f75ca301e | 408 | or DMA, These APIs return the HAL status. |
mbed_official | 631:825f75ca301e | 409 | The end of the data processing will be indicated through the |
mbed_official | 631:825f75ca301e | 410 | dedicated SPI IRQ when using Interrupt mode or the DMA IRQ when |
mbed_official | 631:825f75ca301e | 411 | using DMA mode. |
mbed_official | 631:825f75ca301e | 412 | The HAL_SPI_TxCpltCallback(), HAL_SPI_RxCpltCallback() and HAL_SPI_TxRxCpltCallback() user callbacks |
mbed_official | 631:825f75ca301e | 413 | will be executed respectively at the end of the transmit or Receive process |
mbed_official | 631:825f75ca301e | 414 | The HAL_SPI_ErrorCallback()user callback will be executed when a communication error is detected |
mbed_official | 442:d2c15dda23c1 | 415 | |
mbed_official | 631:825f75ca301e | 416 | (#) APIs provided for these 2 transfer modes (Blocking mode or Non blocking mode using either Interrupt or DMA) |
mbed_official | 631:825f75ca301e | 417 | exist for 1Line (simplex) and 2Lines (full duplex) modes. |
