c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	16 ##### How to use this driver #####
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	17 ==============================================================================
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	18 [..]
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	19 The HASH HAL driver can be used as follows:
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	20 (#)Initialize the HASH low level resources by implementing the HAL_HASH_MspInit():
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	21 (##) Enable the HASH interface clock using __HAL_RCC_HASH_CLK_ENABLE()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	22 (##) In case of using processing APIs based on interrupts (e.g. HAL_HMAC_SHA1_Start_IT())
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	23 (+++) Configure the HASH interrupt priority using HAL_NVIC_SetPriority()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	24 (+++) Enable the HASH IRQ handler using HAL_NVIC_EnableIRQ()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	25 (+++) In HASH IRQ handler, call HAL_HASH_IRQHandler()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	26 (##) In case of using DMA to control data transfer (e.g. HAL_HMAC_SHA1_Start_DMA())
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	27 (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	28 (+++) Configure and enable one DMA stream one for managing data transfer from
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	29 memory to peripheral (input stream). Managing data transfer from
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	30 peripheral to memory can be performed only using CPU
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	31 (+++) Associate the initialized DMA handle to the HASH DMA handle
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	32 using __HAL_LINKDMA()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	33 (+++) Configure the priority and enable the NVIC for the transfer complete
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	34 interrupt on the DMA Stream using HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	35 (#)Initialize the HASH HAL using HAL_HASH_Init(). This function configures mainly:
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	36 (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	37 (##) For HMAC, the encryption key.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	38 (##) For HMAC, the key size used for encryption.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	39 (#)Three processing functions are available:
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	40 (##) Polling mode: processing APIs are blocking functions
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	41 i.e. they process the data and wait till the digest computation is finished
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	42 e.g. HAL_HASH_SHA1_Start()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	43 (##) Interrupt mode: encryption and decryption APIs are not blocking functions
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	44 i.e. they process the data under interrupt
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	45 e.g. HAL_HASH_SHA1_Start_IT()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	46 (##) DMA mode: processing APIs are not blocking functions and the CPU is
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	47 not used for data transfer i.e. the data transfer is ensured by DMA
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	48 e.g. HAL_HASH_SHA1_Start_DMA()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	49 (#)When the processing function is called at first time after HAL_HASH_Init()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	50 the HASH peripheral is initialized and processes the buffer in input.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	51 After that, the digest computation is started.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	52 When processing multi-buffer use the accumulate function to write the
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	53 data in the peripheral without starting the digest computation. In last
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	54 buffer use the start function to input the last buffer ans start the digest
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	55 computation.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	56 (##) e.g. HAL_HASH_SHA1_Accumulate() : write 1st data buffer in the peripheral without starting the digest computation
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	57 (##) write (n-1)th data buffer in the peripheral without starting the digest computation
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	58 (##) HAL_HASH_SHA1_Start() : write (n)th data buffer in the peripheral and start the digest computation
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	59 (#)In HMAC mode, there is no Accumulate API. Only Start API is available.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	60 (#)In case of using DMA, call the DMA start processing e.g. HAL_HASH_SHA1_Start_DMA().
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	61 After that, call the finish function in order to get the digest value
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	62 e.g. HAL_HASH_SHA1_Finish()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	63 (#)Call HAL_HASH_DeInit() to deinitialize the HASH peripheral.
