Bugfix data synchronization after RTE start: In previous version invalid data may be transferred in case the communication is corrupted directly after RTE startup. Root cause was that the data was evaluated without caring if a communication error was reported. In the new version the startup condition and evaluation of data is only done if valid data has been received by the RTE => SPI communication is up and runnig.

c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	13 ##### How to use this driver #####
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	14 ==============================================================================
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	15 [..]
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	16 The HASH HAL driver can be used as follows:
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	17 (#)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	18 (##) 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	19 (##) In case of using processing APIs based on interrupts (e.g. HAL_HMACEx_SHA224_Start())
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	20 (+++) Configure the HASH interrupt priority using HAL_NVIC_SetPriority()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	21 (+++) Enable the HASH IRQ handler using HAL_NVIC_EnableIRQ()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	22 (+++) In HASH IRQ handler, call HAL_HASH_IRQHandler()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	23 (##) In case of using DMA to control data transfer (e.g. HAL_HMACEx_SH224_Start_DMA())
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	24 (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	25 (+++) 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	26 memory to peripheral (input stream). Managing data transfer from
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	27 peripheral to memory can be performed only using CPU
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	28 (+++) 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	29 using __HAL_LINKDMA()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	30 (+++) 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	31 interrupt on the DMA Stream: HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	32 (#)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	33 (##) 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	34 (##) For HMAC, the encryption key.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	35 (##) For HMAC, the key size used for encryption.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	36 (#)Three processing functions are available:
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	37 (##) Polling mode: processing APIs are blocking functions
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	38 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	39 e.g. HAL_HASHEx_SHA224_Start()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	40 (##) 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	41 i.e. they process the data under interrupt
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	42 e.g. HAL_HASHEx_SHA224_Start_IT()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	43 (##) 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	44 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	45 e.g. HAL_HASHEx_SHA224_Start_DMA()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	46 (#)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	47 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	48 After that, the digest computation is started.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	49 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	50 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	51 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	52 computation.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	53 (##) e.g. HAL_HASHEx_SHA224_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	54 (##) 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	55 (##) HAL_HASHEx_SHA224_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	56 (#)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	57 (#)In case of using DMA, call the DMA start processing e.g. HAL_HASHEx_SHA224_Start_DMA().
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	58 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	59 e.g. HAL_HASHEx_SHA224_Finish()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	60 (#)Call HAL_HASH_DeInit() to deinitialize the HASH peripheral.
