****************************************************************************** + * @file stm32f4xx_hal_qspi.c + * @author MCD Application Team + * @version V1.4.0 + * @date 14-August-2015 + * @brief QSPI HAL module driver. + * + * This file provides firmware functions to manage the following + * functionalities of the QuadSPI interface (QSPI). + * + Initialization and de-initialization functions + * + Indirect functional mode management + * + Memory-mapped functional mode management + * + Auto-polling functional mode management + * + Interrupts and flags management + * + DMA channel configuration for indirect functional mode + * + Errors management and abort functionality + * + @verbatim + =============================================================================== + ##### 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 IP 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(). + (+) Configure these QuadSPI pins in alternate mode using HAL_GPIO_Init(). + (+) 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() + 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 and if present the number of bytes. + (+) 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. + (#) 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 : + (+) 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_RxCpltCallback() will be called when the transfer is complete. + (+) In DMA mode, HAL_QSPI_RxHalfCpltCallback() will be called at the half transfer and + 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 + if activated. + (+) Sending Instruction Only Once (SIOO) mode : the activation (or not) of this mode. + (+) 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_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 rised during the last operation. + (#) HAL_QSPI_Abort() function aborts any on-going operation and flushes the fifo. + (#) HAL_QSPI_GetState() function gives the current state of the HAL QuadSPI driver. + + *** Workarounds linked to Silicon Limitation *** + ==================================================== + [..] + (#) Workarounds Implemented inside HAL Driver + (+) Extra data written in the FIFO at the end of a read transfer + + @endverbatim + ****************************************************************************** + * @attention + * + * <h2><center>© COPYRIGHT(c) 2015 STMicroelectronics</center></h2> + * + * Redistribution and use in source and binary forms, with or without modification, + * are permitted provided that the following conditions are met: + * 1.
