##### How to use this driver #####
|
|
===============================================================================
|
|
[..]
|
|
*** Initialization ***
|
|
======================
|
|
[..]
|
|
(#) As prerequisite, fill in the HAL_QSPI_MspInit() :
|
|
(++) Enable QuadSPI clock interface with __HAL_RCC_QSPI_CLK_ENABLE().
|
|
(++) Reset QuadSPI Peripheral with __HAL_RCC_QSPI_FORCE_RESET() and __HAL_RCC_QSPI_RELEASE_RESET().
|
|
(++) Enable the clocks for the QuadSPI GPIOS with __HAL_RCC_GPIOx_CLK_ENABLE().
|
|

|
|
(++) If interrupt mode is used, enable and configure QuadSPI global
|
|
interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ().
|
|
(++) If DMA mode is used, enable the clocks for the QuadSPI DMA channel
|
|
with __HAL_RCC_DMAx_CLK_ENABLE(), configure DMA with HAL_DMA_Init(),
|
|
link it with QuadSPI handle using __HAL_LINKDMA(), enable and configure
|
|
DMA channel global interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ().
|
|
(#) Configure the flash size, the clock prescaler, the fifo threshold, the
|
|
clock mode, the sample shifting and the CS high time using the HAL_QSPI_Init() function.
|
|
|
|
*** Indirect functional mode ***
|
|
================================
|
|
[..]
|
|
(#) Configure the command sequence using the HAL_QSPI_Command() or HAL_QSPI_Command_IT()
|
|

|
if activated.
|
|
(++) Sending Instruction Only Once (SIOO) mode : the activation (or not) of this mode.
|
|
(#) If no data is required for the command, 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_QSPI_CmdCpltCallback() will be called when the transfer is complete.
|
|
(#) For the indirect write mode, use HAL_QSPI_Transmit(), HAL_QSPI_Transmit_DMA() or
|
|
HAL_QSPI_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_QSPI_FifoThresholdCallback() will be called when the fifo threshold
|
|
is reached and HAL_QSPI_TxCpltCallback() will be called when the transfer is complete.

(++) In DMA mode, HAL_QSPI_TxHalfCpltCallback() will be called at the half transfer and
|
|
HAL_QSPI_TxCpltCallback() will be called when the transfer is complete.
|
|
(#) For the indirect read mode, use HAL_QSPI_Receive(), HAL_QSPI_Receive_DMA() or
|
|
HAL_QSPI_Receive_IT() after the command configuration :
|

HAL_QSPI_RxCpltCallback() will be called when the transfer is complete.
|
|
|
|
*** Auto-polling functional mode ***
|
|
====================================
|
|
[..]
|
|
(#) Configure the command sequence and the auto-polling functional mode using the
|
|
HAL_QSPI_AutoPolling() or HAL_QSPI_AutoPolling_IT() functions :
|
|
(++) Instruction phase : the mode used and if present the instruction opcode.
|
|
(++) Address phase : the mode used and if present the size and the address value.
|
|
(++) Alternate-bytes phase : the mode used and if present the size and the alternate
|
|
bytes values.
|
|
(++) Dummy-cycles phase : the number of dummy cycles (mode used is same as data phase).
|
|
(++) Data phase : the mode used.
|
|
(++) Double Data Rate (DDR) mode : the activation (or not) of this mode and the delay

|
|
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_QSPI_StatusMatchCallback() will be called each time the status match is reached.
|
|
|
|
*** Memory-mapped functional mode ***
|
|
=====================================
|
|
[..]
|
|
(#) Configure the command sequence and the memory-mapped functional mode using the
|
|
HAL_QSPI_MemoryMapped() functions :
|
|
(++) Instruction phase : the mode used and if present the instruction opcode.
|
|
(++) Address phase : the mode used and the size.
|
|
(++) Alternate-bytes phase : the mode used and if present the size and the alternate
|
|
bytes values.
|
|
(++) Dummy-cycles phase : the number of dummy cycles (mode used is same as data phase).
|
|
(++) Data phase : the mode used.
|
|
(++) Double Data Rate (DDR) mode : the activation (or not) of this mode and the delay
|
|
if activated.
|
|
(++) Sending Instruction Only Once (SIOO) mode : the activation (or not) of this mode.
|
|
(++) The timeout activation and the timeout period.
|
|
(#) After the configuration, the QuadSPI will be used as soon as an access on the AHB is done on
|
|
the address range. HAL_QSPI_TimeOutCallback() will be called when the timeout expires.
|
|
|
|
*** Errors management and abort functionality ***
|
|
=================================================
|
|
[..]
|
|
(#) HAL_QSPI_GetError() function gives the error raised during the last operation.
|
|
(#) HAL_QSPI_Abort() and HAL_QSPI_Abort_IT() 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_QSPI_AbortCpltCallback() will be called when
|
|
the transfer complete bit is set.
|
|
|
|
*** Control functions ***
|
|
=========================
|
|
[..]
|
|
(#) HAL_QSPI_GetState() function gives the current state of the HAL QuadSPI driver.
|
|
(#) HAL_QSPI_SetTimeout() function configures the timeout value used in the driver.
|
|
(#) HAL_QSPI_SetFifoThreshold() function configures the threshold on the Fifo of the QSPI IP.
|
|
(#) HAL_QSPI_GetFifoThreshold() function gives the current of the Fifo's threshold
|
|
(#) HAL_QSPI_SetFlashID() function configures the index of the flash memory to be accessed.
|
|
|
|
*** Callback registration ***
|
|
=============================================
|
|
[..]
|
|
The compilation define USE_HAL_QSPI_REGISTER_CALLBACKS when set to 1
|
|
allows the user to configure dynamically the driver callbacks.
|
|
|
|
Use Functions HAL_QSPI_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 : QSPI MspInit.
|
|
(+) MspDeInitCallback : QSPI MspDeInit.
|
|
This function takes as parameters the HAL peripheral handle, the Callback ID
|
|
and a pointer to the user callback function.
|
|
|
|
Use function HAL_QSPI_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 : QSPI MspInit.
|
|
(+) MspDeInitCallback : QSPI MspDeInit.
|
|
This function) takes as parameters the HAL peripheral handle and the Callback ID.
|
|
|
|
By default, after the HAL_QSPI_Init and if the state is HAL_QSPI_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_QSPI_Init
|
|
and HAL_QSPI_DeInit only when these callbacks are null (not registered beforehand).
|
|
If not, MspInit or MspDeInit are not null, the HAL_QSPI_Init and HAL_QSPI_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_QSPI_RegisterCallback before calling HAL_QSPI_DeInit
|
|
or HAL_QSPI_Init function.
|
|
|
|
When The compilation define USE_HAL_QSPI_REGISTER_CALLBACKS is set to 0 or
|
|
not defined, the callback registering feature is not available
|
|
and weak (surcharged) callbacks are used.
