Deactivate deco gas calculation option:
In the previous version had the option to consider a deco gas i the calculation or not. Reason for this was to have the automatic gas suggestion available while the deco calculation is still based on the current gas.
This might cause a critical situation in case the diver is not sure if the option is active or not => In the new version the TTS / deco is always calculated considering all deco gases.

==============================================================================+ −
##### How to use this driver #####+ −
==============================================================================+ −
[..]+ −
The CRYP HAL driver can be used as follows:+ −
+ −
(#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit():+ −
(##) Enable the CRYP interface clock using __HAL_RCC_CRYP_CLK_ENABLE()+ −
(##) In case of using interrupts (e.g. HAL_CRYP_AESECB_Encrypt_IT())+ −
(+++) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority()+ −
(+++) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ()+ −
(+++) In CRYP IRQ handler, call HAL_CRYP_IRQHandler()+ −
(##) In case of using DMA to control data transfer (e.g. HAL_CRYP_AESECB_Encrypt_DMA())+ −
(+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()+ −
(+++) Configure and enable two DMA streams one for managing data transfer from+ −
memory to peripheral (input stream) and another stream for managing data+ −
transfer from peripheral to memory (output stream)+ −
(+++) Associate the initialized DMA handle to the CRYP DMA handle+ −
using __HAL_LINKDMA()+ −
(+++) Configure the priority and enable the NVIC for the transfer complete+ −
interrupt on the two DMA Streams. The output stream should have higher+ −
priority than the input stream HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()+ −
+ −
(#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures mainly:+ −
(##) The data type: 1-bit, 8-bit, 16-bit and 32-bit+ −
(##) The key size: 128, 192 and 256. This parameter is relevant only for AES+ −
(##) The encryption/decryption key. It's size depends on the algorithm+ −
used for encryption/decryption+ −
(##) The initialization vector (counter). It is not used ECB mode.+ −
+ −
(#)Three processing (encryption/decryption) functions are available:+ −
(##) Polling mode: encryption and decryption APIs are blocking functions+ −
i.e. they process the data and wait till the processing is finished,+ −
e.g. HAL_CRYP_AESCBC_Encrypt()+ −
(##) Interrupt mode: encryption and decryption APIs are not blocking functions+ −
i.e. they process the data under interrupt,+ −
e.g. HAL_CRYP_AESCBC_Encrypt_IT()+ −
(##) DMA mode: encryption and decryption APIs are not blocking functions+ −
i.e. the data transfer is ensured by DMA,+ −
e.g. HAL_CRYP_AESCBC_Encrypt_DMA()+ −
+ −
(#)When the processing function is called at first time after HAL_CRYP_Init()+ −
the CRYP peripheral is initialized and processes the buffer in input.+ −
At second call, the processing function performs an append of the already+ −
processed buffer.+ −
When a new data block is to be processed, call HAL_CRYP_Init() then the+ −
processing function.+ −
+ −
(#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.+ −
+ −
