<> | 149:156823d33999 | 20 | ============================================================================== |
<> | 149:156823d33999 | 21 | [..] |
<> | 149:156823d33999 | 22 | The CRYP HAL driver can be used as follows: |
<> | 149:156823d33999 | 23 | |
<> | 149:156823d33999 | 24 | (#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit(): |
<> | 149:156823d33999 | 25 | (##) Enable the CRYP interface clock using __HAL_RCC_CRYP_CLK_ENABLE() |
<> | 149:156823d33999 | 26 | (##) In case of using interrupts (e.g. HAL_CRYP_AESECB_Encrypt_IT()) |
<> | 149:156823d33999 | 27 | (+) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority() |
<> | 149:156823d33999 | 28 | (+) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ() |
<> | 149:156823d33999 | 29 | (+) In CRYP IRQ handler, call HAL_CRYP_IRQHandler() |
<> | 149:156823d33999 | 30 | (##) In case of using DMA to control data transfer (e.g. HAL_CRYP_AESECB_Encrypt_DMA()) |
<> | 149:156823d33999 | 31 | (+) Enable the DMA2 interface clock using |
<> | 149:156823d33999 | 32 | (++) __HAL_RCC_DMA2_CLK_ENABLE() |
<> | 149:156823d33999 | 33 | (+) Configure and enable two DMA Channels one for managing data transfer from |
<> | 149:156823d33999 | 34 | memory to peripheral (input channel) and another channel for managing data |
<> | 149:156823d33999 | 35 | transfer from peripheral to memory (output channel) |
<> | 149:156823d33999 | 36 | (+) Associate the initialized DMA handle to the CRYP DMA handle |
<> | 149:156823d33999 | 37 | using __HAL_LINKDMA() |
<> | 149:156823d33999 | 38 | (+) Configure the priority and enable the NVIC for the transfer complete |
<> | 149:156823d33999 | 39 | interrupt on the two DMA Streams. The output stream should have higher |
<> | 149:156823d33999 | 40 | priority than the input stream. |
<> | 149:156823d33999 | 41 | (++) HAL_NVIC_SetPriority() |
<> | 149:156823d33999 | 42 | (++) HAL_NVIC_EnableIRQ() |
<> | 149:156823d33999 | 43 | |
<> | 149:156823d33999 | 44 | (#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures mainly: |
<> | 149:156823d33999 | 45 | (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit |
<> | 149:156823d33999 | 46 | (##) The encryption/decryption key. |
<> | 149:156823d33999 | 47 | (##) The initialization vector (counter). It is not used ECB mode. |
<> | 149:156823d33999 | 48 | |
<> | 149:156823d33999 | 49 | (#)Three processing (encryption/decryption) functions are available: |
<> | 149:156823d33999 | 50 | (##) Polling mode: encryption and decryption APIs are blocking functions |
<> | 149:156823d33999 | 51 | i.e. they process the data and wait till the processing is finished |
<> | 149:156823d33999 | 52 | e.g. HAL_CRYP_AESCBC_Encrypt() |
<> | 149:156823d33999 | 53 | (##) Interrupt mode: encryption and decryption APIs are not blocking functions |
<> | 149:156823d33999 | 54 | i.e. they process the data under interrupt |
<> | 149:156823d33999 | 55 | e.g. HAL_CRYP_AESCBC_Encrypt_IT() |
<> | 149:156823d33999 | 56 | (##) DMA mode: encryption and decryption APIs are not blocking functions |
<> | 149:156823d33999 | 57 | i.e. the data transfer is ensured by DMA |
<> | 149:156823d33999 | 58 | e.g. HAL_CRYP_AESCBC_Encrypt_DMA() |
<> | 149:156823d33999 | 59 | |
<> | 149:156823d33999 | 60 | (#)When the processing function is called for the first time after HAL_CRYP_Init() |
<> | 149:156823d33999 | 61 | the CRYP peripheral is initialized and processes the buffer in input. |
<> | 149:156823d33999 | 62 | At second call, the processing function performs an append of the already |
<> | 149:156823d33999 | 63 | processed buffer. |
<> | 149:156823d33999 | 64 | When a new data block is to be processed, call HAL_CRYP_Init() then the |
<> | 149:156823d33999 | 65 | processing function. |
<> | 149:156823d33999 | 66 | |
<> | 149:156823d33999 | 67 | (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral. |
