##### How to use this driver #####
===============================================================================
[..]
*** Initialization ***
======================
[..]
As prerequisite, fill in the HAL_OSPI_MspInit() :
(+) Enable OctoSPI and OctoSPIM clocks interface with __HAL_RCC_OSPIx_CLK_ENABLE().
(+) Reset OctoSPI Peripheral with __HAL_RCC_OSPIx_FORCE_RESET() and __HAL_RCC_OSPIx_RELEASE_RESET().
(+) Enable the clocks for the OctoSPI GPIOS with __HAL_RCC_GPIOx_CLK_ENABLE().
(+) Configure these OctoSPI pins in alternate mode using HAL_GPIO_Init().
(+) If interrupt or DMA mode is used, enable and configure OctoSPI global
interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ().
(+) If DMA mode is used, enable the clocks for the OctoSPI DMA channel
with __HAL_RCC_DMAx_CLK_ENABLE(), configure DMA with HAL_DMA_Init(),
link it with OctoSPI handle using __HAL_LINKDMA(), enable and configure
DMA channel global interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ().
[..]
Configure the fifo threshold, the dual-quad mode, the memory type, the
device size, the CS high time, the free running clock, the clock mode,
the wrap size, the clock prescaler, the sample shifting, the hold delay
and the CS boundary using the HAL_OSPI_Init() function.
[..]
When using Hyperbus, configure the RW recovery time, the access time,
the write latency and the latency mode unsing the HAL_OSPI_HyperbusCfg()
function.
*** Indirect functional mode ***
================================
[..]
In regular mode, configure the command sequence using the HAL_OSPI_Command()
or HAL_OSPI_Command_IT() functions :
(+) Instruction phase : the mode used and if present the size, the instruction
opcode and the DTR mode.
(+) Address phase : the mode used and if present the size, the address
value and the DTR mode.
(+) Alternate-bytes phase : the mode used and if present the size, the
alternate bytes values and the DTR mode.
(+) Dummy-cycles phase : the number of dummy cycles (mode used is same as data phase).
(+) Data phase : the mode used and if present the number of bytes and the DTR mode.
(+) Data strobe (DQS) mode : the activation (or not) of this mode
(+) Sending Instruction Only Once (SIOO) mode : the activation (or not) of this mode.
(+) Flash identifier : in dual-quad mode, indicates which flash is concerned
(+) Operation type : always common configuration
[..]
In Hyperbus mode, configure the command sequence using the HAL_OSPI_HyperbusCmd()
function :
(+) Address space : indicate if the access will be done in register or memory
(+) Address size
(+) Number of data
(+) Data strobe (DQS) mode : the activation (or not) of this mode
[..]
If no data is required for the command (only for regular mode, not for
Hyperbus mode), it is sent directly to the memory :
(+) In polling mode, the output of the function is done when the transfer is complete.
(+) In interrupt mode, HAL_OSPI_CmdCpltCallback() will be called when the transfer is complete.
[..]
For the indirect write mode, use HAL_OSPI_Transmit(), HAL_OSPI_Transmit_DMA() or
HAL_OSPI_Transmit_IT() after the command configuration :
(+) In polling mode, the output of the function is done when the transfer is complete.
(+) In interrupt mode, HAL_OSPI_FifoThresholdCallback() will be called when the fifo threshold
is reached and HAL_OSPI_TxCpltCallback() will be called when the transfer is complete.
(+) In DMA mode, HAL_OSPI_TxHalfCpltCallback() will be called at the half transfer and
HAL_OSPI_TxCpltCallback() will be called when the transfer is complete.
[..]
For the indirect read mode, use HAL_OSPI_Receive(), HAL_OSPI_Receive_DMA() or
HAL_OSPI_Receive_IT() after the command configuration :
(+) In polling mode, the output of the function is done when the transfer is complete.
(+) In interrupt mode, HAL_OSPI_FifoThresholdCallback() will be called when the fifo threshold
is reached and HAL_OSPI_RxCpltCallback() will be called when the transfer is complete.
(+) In DMA mode, HAL_OSPI_RxHalfCpltCallback() will be called at the half transfer and
HAL_OSPI_RxCpltCallback() will be called when the transfer is complete.
*** Auto-polling functional mode ***
====================================
[..]
Configure the command sequence by the same way than the indirect mode
[..]
Configure the auto-polling functional mode using the HAL_OSPI_AutoPolling()
or HAL_OSPI_AutoPolling_IT() functions :
(+) The size of the status bytes, the match value, the mask used, the match mode (OR/AND),
the polling interval and the automatic stop activation.
[..]
After the configuration :
(+) In polling mode, the output of the function is done when the status match is reached. The
automatic stop is activated to avoid an infinite loop.
(+) In interrupt mode, HAL_OSPI_StatusMatchCallback() will be called each time the status match is reached.
*** MDMA functional mode ***
====================================
[..]
Configure the SourceInc and DestinationInc of MDMA parameters in the HAL_OSPI_MspInit() function :
(+) MDMA settings for write operation :
(++) The DestinationInc should be MDMA_DEST_INC_DISABLE
(++) The SourceInc must be a value of @ref MDMA_Source_increment_mode (Except the MDMA_SRC_INC_DOUBLEWORD).
(++) The SourceDataSize must be a value of @ref MDMA Source data size (Except the MDMA_SRC_DATASIZE_DOUBLEWORD)
aligned with @ref MDMA_Source_increment_mode .
(++) The DestDataSize must be a value of @ref MDMA Destination data size (Except the MDMA_DEST_DATASIZE_DOUBLEWORD)
(+) MDMA settings for read operation :
(++) The SourceInc should be MDMA_SRC_INC_DISABLE
(++) The DestinationInc must be a value of @ref MDMA_Destination_increment_mode (Except the MDMA_DEST_INC_DOUBLEWORD).
(++) The SourceDataSize must be a value of @ref MDMA Source data size (Except the MDMA_SRC_DATASIZE_DOUBLEWORD) .
(++) The DestDataSize must be a value of @ref MDMA Destination data size (Except the MDMA_DEST_DATASIZE_DOUBLEWORD)
aligned with @ref MDMA_Destination_increment_mode.
(+) The buffer Transfer Length (BufferTransferLength) = number of bytes in the FIFO (FifoThreshold) of the Octospi.
[..]
In case of wrong MDMA setting
(+) For write operation :
(++) If the DestinationInc is different to MDMA_DEST_INC_DISABLE , it will be disabled by the HAL_OSPI_Transmit_DMA().
(+) For read operation :
(++) If the SourceInc is not set to MDMA_SRC_INC_DISABLE , it will be disabled by the HAL_OSPI_Receive_DMA().
*** Memory-mapped functional mode ***
=====================================
[..]
Configure the command sequence by the same way than the indirect mode except
for the operation type in regular mode :
(+) Operation type equals to read configuration : the command configuration
applies to read access in memory-mapped mode
(+) Operation type equals to write configuration : the command configuration
applies to write access in memory-mapped mode
(+) Both read and write configuration should be performed before activating
memory-mapped mode
[..]
Configure the memory-mapped functional mode using the HAL_OSPI_MemoryMapped()
functions :
(+) The timeout activation and the timeout period.
[..]
After the configuration, the OctoSPI will be used as soon as an access on the AHB is done on
the address range. HAL_OSPI_TimeOutCallback() will be called when the timeout expires.
*** Errors management and abort functionality ***
=================================================
[..]
HAL_OSPI_GetError() function gives the error raised during the last operation.
[..]
HAL_OSPI_Abort() and HAL_OSPI_AbortIT() functions aborts any on-going operation and
flushes the fifo :
(+) In polling mode, the output of the function is done when the transfer
complete bit is set and the busy bit cleared.
(+) In interrupt mode, HAL_OSPI_AbortCpltCallback() will be called when
the transfer complete bit is set.
*** Control functions ***
=========================
[..]
HAL_OSPI_GetState() function gives the current state of the HAL OctoSPI driver.
[..]
HAL_OSPI_SetTimeout() function configures the timeout value used in the driver.
[..]
HAL_OSPI_SetFifoThreshold() function configures the threshold on the Fifo of the OSPI Peripheral.
[..]
HAL_OSPI_GetFifoThreshold() function gives the current of the Fifo's threshold
*** IO manager configuration functions ***
==========================================
[..]
HAL_OSPIM_Config() function configures the IO manager for the OctoSPI instance.
*** Callback registration ***
=============================================
[..]
The compilation define USE_HAL_OSPI_REGISTER_CALLBACKS when set to 1
allows the user to configure dynamically the driver callbacks.
[..]
Use function HAL_OSPI_RegisterCallback() to register a user callback,
it allows to register following callbacks:
(+) ErrorCallback : callback when error occurs.
(+) AbortCpltCallback : callback when abort is completed.
(+) FifoThresholdCallback : callback when the fifo threshold is reached.
(+) CmdCpltCallback : callback when a command without data is completed.
(+) RxCpltCallback : callback when a reception transfer is completed.
(+) TxCpltCallback : callback when a transmission transfer is completed.
(+) RxHalfCpltCallback : callback when half of the reception transfer is completed.
(+) TxHalfCpltCallback : callback when half of the transmission transfer is completed.
(+) StatusMatchCallback : callback when a status match occurs.
(+) TimeOutCallback : callback when the timeout perioed expires.
(+) MspInitCallback : OSPI MspInit.
(+) MspDeInitCallback : OSPI MspDeInit.
[..]
This function takes as parameters the HAL peripheral handle, the Callback ID
and a pointer to the user callback function.
[..]
Use function HAL_OSPI_UnRegisterCallback() to reset a callback to the default
weak (surcharged) function. It allows to reset following callbacks:
(+) ErrorCallback : callback when error occurs.
(+) AbortCpltCallback : callback when abort is completed.
(+) FifoThresholdCallback : callback when the fifo threshold is reached.
(+) CmdCpltCallback : callback when a command without data is completed.
(+) RxCpltCallback : callback when a reception transfer is completed.
(+) TxCpltCallback : callback when a transmission transfer is completed.
(+) RxHalfCpltCallback : callback when half of the reception transfer is completed.
(+) TxHalfCpltCallback : callback when half of the transmission transfer is completed.
(+) StatusMatchCallback : callback when a status match occurs.
(+) TimeOutCallback : callback when the timeout perioed expires.
(+) MspInitCallback : OSPI MspInit.
(+) MspDeInitCallback : OSPI MspDeInit.
[..]
This function) takes as parameters the HAL peripheral handle and the Callback ID.
[..]
By default, after the HAL_OSPI_Init() and if the state is HAL_OSPI_STATE_RESET
all callbacks are reset to the corresponding legacy weak (surcharged) functions.
Exception done for MspInit and MspDeInit callbacks that are respectively
reset to the legacy weak (surcharged) functions in the HAL_OSPI_Init()
and HAL_OSPI_DeInit() only when these callbacks are null (not registered beforehand).
If not, MspInit or MspDeInit are not null, the HAL_OSPI_Init() and HAL_OSPI_DeInit()
keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
[..]
Callbacks can be registered/unregistered in READY state only.
Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
during the Init/DeInit.
In that case first register the MspInit/MspDeInit user callbacks
using HAL_OSPI_RegisterCallback() before calling HAL_OSPI_DeInit()
or HAL_OSPI_Init() function.
[..]
When The compilation define USE_HAL_OSPI_REGISTER_CALLBACKS is set to 0 or
not defined, the callback registering feature is not available
and weak (surcharged) callbacks are used.
