| mbed_official | 235:685d5f11838f | 18 | ##### How to use this driver ##### |
| mbed_official | 235:685d5f11838f | 19 | ============================================================================== |
| mbed_official | 235:685d5f11838f | 20 | [..] |
| mbed_official | 235:685d5f11838f | 21 | The HASH HAL driver can be used as follows: |
| mbed_official | 235:685d5f11838f | 22 | (#)Initialize the HASH low level resources by implementing the HAL_HASH_MspInit(): |
| mbed_official | 532:fe11edbda85c | 23 | (##) Enable the HASH interface clock using __HAL_RCC_HASH_CLK_ENABLE() |
| mbed_official | 235:685d5f11838f | 24 | (##) In case of using processing APIs based on interrupts (e.g. HAL_HMAC_SHA1_Start_IT()) |
| mbed_official | 235:685d5f11838f | 25 | (+++) Configure the HASH interrupt priority using HAL_NVIC_SetPriority() |
| mbed_official | 235:685d5f11838f | 26 | (+++) Enable the HASH IRQ handler using HAL_NVIC_EnableIRQ() |
| mbed_official | 235:685d5f11838f | 27 | (+++) In HASH IRQ handler, call HAL_HASH_IRQHandler() |
| mbed_official | 235:685d5f11838f | 28 | (##) In case of using DMA to control data transfer (e.g. HAL_HMAC_SHA1_Start_DMA()) |
| mbed_official | 235:685d5f11838f | 29 | (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE() |
| mbed_official | 235:685d5f11838f | 30 | (+++) Configure and enable one DMA stream one for managing data transfer from |
| mbed_official | 235:685d5f11838f | 31 | memory to peripheral (input stream). Managing data transfer from |
| mbed_official | 235:685d5f11838f | 32 | peripheral to memory can be performed only using CPU |
| mbed_official | 235:685d5f11838f | 33 | (+++) Associate the initialized DMA handle to the HASH DMA handle |
| mbed_official | 235:685d5f11838f | 34 | using __HAL_LINKDMA() |
| mbed_official | 235:685d5f11838f | 35 | (+++) Configure the priority and enable the NVIC for the transfer complete |
| mbed_official | 235:685d5f11838f | 36 | interrupt on the DMA Stream using HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ() |
| mbed_official | 235:685d5f11838f | 37 | (#)Initialize the HASH HAL using HAL_HASH_Init(). This function configures mainly: |
| mbed_official | 235:685d5f11838f | 38 | (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit. |
| mbed_official | 235:685d5f11838f | 39 | (##) For HMAC, the encryption key. |
| mbed_official | 235:685d5f11838f | 40 | (##) For HMAC, the key size used for encryption. |
| mbed_official | 235:685d5f11838f | 41 | (#)Three processing functions are available: |
| mbed_official | 235:685d5f11838f | 42 | (##) Polling mode: processing APIs are blocking functions |
| mbed_official | 235:685d5f11838f | 43 | i.e. they process the data and wait till the digest computation is finished |
| mbed_official | 235:685d5f11838f | 44 | e.g. HAL_HASH_SHA1_Start() |
| mbed_official | 235:685d5f11838f | 45 | (##) Interrupt mode: encryption and decryption APIs are not blocking functions |
| mbed_official | 235:685d5f11838f | 46 | i.e. they process the data under interrupt |
| mbed_official | 235:685d5f11838f | 47 | e.g. HAL_HASH_SHA1_Start_IT() |
| mbed_official | 235:685d5f11838f | 48 | (##) DMA mode: processing APIs are not blocking functions and the CPU is |
| mbed_official | 235:685d5f11838f | 49 | not used for data transfer i.e. the data transfer is ensured by DMA |
| mbed_official | 235:685d5f11838f | 50 | e.g. HAL_HASH_SHA1_Start_DMA() |
| mbed_official | 235:685d5f11838f | 51 | (#)When the processing function is called at first time after HAL_HASH_Init() |
| mbed_official | 235:685d5f11838f | 52 | the HASH peripheral is initialized and processes the buffer in input. |
| mbed_official | 235:685d5f11838f | 53 | After that, the digest computation is started. |
| mbed_official | 235:685d5f11838f | 54 | When processing multi-buffer use the accumulate function to write the |
| mbed_official | 235:685d5f11838f | 55 | data in the peripheral without starting the digest computation. In last |
| mbed_official | 235:685d5f11838f | 56 | buffer use the start function to input the last buffer ans start the digest |
| mbed_official | 235:685d5f11838f | 57 | computation. |
| mbed_official | 235:685d5f11838f | 58 | (##) e.g. HAL_HASH_SHA1_Accumulate() : write 1st data buffer in the peripheral without starting the digest computation |
| mbed_official | 235:685d5f11838f | 59 | (##) write (n-1)th data buffer in the peripheral without starting the digest computation |
| mbed_official | 235:685d5f11838f | 60 | (##) HAL_HASH_SHA1_Start() : write (n)th data buffer in the peripheral and start the digest computation |
| mbed_official | 235:685d5f11838f | 61 | (#)In HMAC mode, there is no Accumulate API. Only Start API is available. |
| mbed_official | 235:685d5f11838f | 62 | (#)In case of using DMA, call the DMA start processing e.g. HAL_HASH_SHA1_Start_DMA(). |
| mbed_official | 235:685d5f11838f | 63 | After that, call the finish function in order to get the digest value |
| mbed_official | 235:685d5f11838f | 64 | e.g. HAL_HASH_SHA1_Finish() |
| mbed_official | 235:685d5f11838f | 65 | (#)Call HAL_HASH_DeInit() to deinitialize the HASH peripheral. |
