mbed_official 87:085cde657901 18 ##### How to use this driver #####
mbed_official 87:085cde657901 19 ==============================================================================
mbed_official 87:085cde657901 20 [..]
mbed_official 87:085cde657901 21 The HASH HAL driver can be used as follows:
mbed_official 87:085cde657901 22 (#)Initialize the HASH low level resources by implementing the HAL_HASH_MspInit():
mbed_official 87:085cde657901 23 (##) Enable the HASH interface clock using __HASH_CLK_ENABLE()
mbed_official 87:085cde657901 24 (##) In case of using processing APIs based on interrupts (e.g. HAL_HMAC_SHA1_Start_IT())
mbed_official 87:085cde657901 25 (+++) Configure the HASH interrupt priority using HAL_NVIC_SetPriority()
mbed_official 87:085cde657901 26 (+++) Enable the HASH IRQ handler using HAL_NVIC_EnableIRQ()
mbed_official 87:085cde657901 27 (+++) In HASH IRQ handler, call HAL_HASH_IRQHandler()
mbed_official 87:085cde657901 28 (##) In case of using DMA to control data transfer (e.g. HAL_HMAC_SHA1_Start_DMA())
mbed_official 87:085cde657901 29 (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()
mbed_official 87:085cde657901 30 (+++) Configure and enable one DMA stream one for managing data transfer from
mbed_official 87:085cde657901 31 memory to peripheral (input stream). Managing data transfer from
mbed_official 87:085cde657901 32 peripheral to memory can be performed only using CPU
mbed_official 87:085cde657901 33 (+++) Associate the initialized DMA handle to the HASH DMA handle
mbed_official 87:085cde657901 34 using __HAL_LINKDMA()
mbed_official 87:085cde657901 35 (+++) Configure the priority and enable the NVIC for the transfer complete
mbed_official 87:085cde657901 36 interrupt on the DMA Stream using HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()
mbed_official 87:085cde657901 37 (#)Initialize the HASH HAL using HAL_HASH_Init(). This function configures mainly:
mbed_official 87:085cde657901 38 (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit.
mbed_official 87:085cde657901 39 (##) For HMAC, the encryption key.
mbed_official 87:085cde657901 40 (##) For HMAC, the key size used for encryption.
mbed_official 87:085cde657901 41 (#)Three processing functions are available:
mbed_official 87:085cde657901 42 (##) Polling mode: processing APIs are blocking functions
mbed_official 87:085cde657901 43 i.e. they process the data and wait till the digest computation is finished
mbed_official 87:085cde657901 44 e.g. HAL_HASH_SHA1_Start()
mbed_official 87:085cde657901 45 (##) Interrupt mode: encryption and decryption APIs are not blocking functions
mbed_official 87:085cde657901 46 i.e. they process the data under interrupt
mbed_official 87:085cde657901 47 e.g. HAL_HASH_SHA1_Start_IT()
mbed_official 87:085cde657901 48 (##) DMA mode: processing APIs are not blocking functions and the CPU is
mbed_official 87:085cde657901 49 not used for data transfer i.e. the data transfer is ensured by DMA
mbed_official 87:085cde657901 50 e.g. HAL_HASH_SHA1_Start_DMA()
mbed_official 87:085cde657901 51 (#)When the processing function is called at first time after HAL_HASH_Init()
mbed_official 87:085cde657901 52 the HASH peripheral is initialized and processes the buffer in input.
mbed_official 87:085cde657901 53 After that, the digest computation is started.
mbed_official 87:085cde657901 54 When processing multi-buffer use the accumulate function to write the
mbed_official 87:085cde657901 55 data in the peripheral without starting the digest computation. In last
mbed_official 87:085cde657901 56 buffer use the start function to input the last buffer ans start the digest
mbed_official 87:085cde657901 57 computation.
mbed_official 87:085cde657901 58 (##) e.g. HAL_HASH_SHA1_Accumulate() : write 1st data buffer in the peripheral without starting the digest computation
mbed_official 87:085cde657901 59 (##) write (n-1)th data buffer in the peripheral without starting the digest computation
mbed_official 87:085cde657901 60 (##) HAL_HASH_SHA1_Start() : write (n)th data buffer in the peripheral and start the digest computation
mbed_official 87:085cde657901 61 (#)In HMAC mode, there is no Accumulate API. Only Start API is available.
mbed_official 87:085cde657901 62 (#)In case of using DMA, call the DMA start processing e.g. HAL_HASH_SHA1_Start_DMA().
mbed_official 87:085cde657901 63 After that, call the finish function in order to get the digest value
mbed_official 87:085cde657901 64 e.g. HAL_HASH_SHA1_Finish()
mbed_official 87:085cde657901 65 (#)Call HAL_HASH_DeInit() to deinitialize the HASH peripheral.
