mbed_official | 573:ad23fe03a082 | 14 | ============================================================================== |
mbed_official | 573:ad23fe03a082 | 15 | ##### How to use this driver ##### |
mbed_official | 573:ad23fe03a082 | 16 | ============================================================================== |
mbed_official | 573:ad23fe03a082 | 17 | [..] |
mbed_official | 573:ad23fe03a082 | 18 | The HASH HAL driver can be used as follows: |
mbed_official | 573:ad23fe03a082 | 19 | (#)Initialize the HASH low level resources by implementing the HAL_HASH_MspInit(): |
mbed_official | 573:ad23fe03a082 | 20 | (##) Enable the HASH interface clock using __HAL_RCC_HASH_CLK_ENABLE() |
mbed_official | 573:ad23fe03a082 | 21 | (##) In case of using processing APIs based on interrupts (e.g. HAL_HMACEx_SHA224_Start()) |
mbed_official | 573:ad23fe03a082 | 22 | (+++) Configure the HASH interrupt priority using HAL_NVIC_SetPriority() |
mbed_official | 573:ad23fe03a082 | 23 | (+++) Enable the HASH IRQ handler using HAL_NVIC_EnableIRQ() |
mbed_official | 573:ad23fe03a082 | 24 | (+++) In HASH IRQ handler, call HAL_HASH_IRQHandler() |
mbed_official | 573:ad23fe03a082 | 25 | (##) In case of using DMA to control data transfer (e.g. HAL_HMACEx_SH224_Start_DMA()) |
mbed_official | 573:ad23fe03a082 | 26 | (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE() |
mbed_official | 573:ad23fe03a082 | 27 | (+++) Configure and enable one DMA stream one for managing data transfer from |
mbed_official | 573:ad23fe03a082 | 28 | memory to peripheral (input stream). Managing data transfer from |
mbed_official | 573:ad23fe03a082 | 29 | peripheral to memory can be performed only using CPU |
mbed_official | 573:ad23fe03a082 | 30 | (+++) Associate the initialized DMA handle to the HASH DMA handle |
mbed_official | 573:ad23fe03a082 | 31 | using __HAL_LINKDMA() |
mbed_official | 573:ad23fe03a082 | 32 | (+++) Configure the priority and enable the NVIC for the transfer complete |
mbed_official | 573:ad23fe03a082 | 33 | interrupt on the DMA Stream: HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ() |
mbed_official | 573:ad23fe03a082 | 34 | (#)Initialize the HASH HAL using HAL_HASH_Init(). This function configures mainly: |
mbed_official | 573:ad23fe03a082 | 35 | (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit. |
mbed_official | 573:ad23fe03a082 | 36 | (##) For HMAC, the encryption key. |
mbed_official | 573:ad23fe03a082 | 37 | (##) For HMAC, the key size used for encryption. |
mbed_official | 573:ad23fe03a082 | 38 | (#)Three processing functions are available: |
mbed_official | 573:ad23fe03a082 | 39 | (##) Polling mode: processing APIs are blocking functions |
mbed_official | 573:ad23fe03a082 | 40 | i.e. they process the data and wait till the digest computation is finished |
mbed_official | 573:ad23fe03a082 | 41 | e.g. HAL_HASHEx_SHA224_Start() |
mbed_official | 573:ad23fe03a082 | 42 | (##) Interrupt mode: encryption and decryption APIs are not blocking functions |
mbed_official | 573:ad23fe03a082 | 43 | i.e. they process the data under interrupt |
mbed_official | 573:ad23fe03a082 | 44 | e.g. HAL_HASHEx_SHA224_Start_IT() |
mbed_official | 573:ad23fe03a082 | 45 | (##) DMA mode: processing APIs are not blocking functions and the CPU is |
mbed_official | 573:ad23fe03a082 | 46 | not used for data transfer i.e. the data transfer is ensured by DMA |
mbed_official | 573:ad23fe03a082 | 47 | e.g. HAL_HASHEx_SHA224_Start_DMA() |
mbed_official | 573:ad23fe03a082 | 48 | (#)When the processing function is called at first time after HAL_HASH_Init() |
mbed_official | 573:ad23fe03a082 | 49 | the HASH peripheral is initialized and processes the buffer in input. |
mbed_official | 573:ad23fe03a082 | 50 | After that, the digest computation is started. |
mbed_official | 573:ad23fe03a082 | 51 | When processing multi-buffer use the accumulate function to write the |
mbed_official | 573:ad23fe03a082 | 52 | data in the peripheral without starting the digest computation. In last |
mbed_official | 573:ad23fe03a082 | 53 | buffer use the start function to input the last buffer ans start the digest |
mbed_official | 573:ad23fe03a082 | 54 | computation. |
mbed_official | 573:ad23fe03a082 | 55 | (##) e.g. HAL_HASHEx_SHA224_Accumulate() : write 1st data buffer in the peripheral without starting the digest computation |
mbed_official | 573:ad23fe03a082 | 56 | (##) write (n-1)th data buffer in the peripheral without starting the digest computation |
mbed_official | 573:ad23fe03a082 | 57 | (##) HAL_HASHEx_SHA224_Start() : write (n)th data buffer in the peripheral and start the digest computation |
mbed_official | 573:ad23fe03a082 | 58 | (#)In HMAC mode, there is no Accumulate API. Only Start API is available. |
mbed_official | 573:ad23fe03a082 | 59 | (#)In case of using DMA, call the DMA start processing e.g. HAL_HASHEx_SHA224_Start_DMA(). |
mbed_official | 573:ad23fe03a082 | 60 | After that, call the finish function in order to get the digest value |
mbed_official | 573:ad23fe03a082 | 61 | e.g. HAL_HASHEx_SHA224_Finish() |
mbed_official | 573:ad23fe03a082 | 62 | (#)Call HAL_HASH_DeInit() to deinitialize the HASH peripheral. |
