Detailed Description
This file includes a standard driver for the N25Q128A QSPI memory mounted on STM32746G-Discovery board.
- Version:
- V2.0.0
- Date:
- 30-December-2016
============================================================================== ##### How to use this driver ##### ============================================================================== [..] (#) This driver is used to drive the N25Q128A QSPI external memory mounted on STM32746G-Discovery board. (#) This driver need a specific component driver (N25Q128A) to be included with. (#) Initialization steps: (++) Initialize the QPSI external memory using the BSP_QSPI_Init() function. This function includes the MSP layer hardware resources initialization and the QSPI interface with the external memory. (#) QSPI memory operations (++) QSPI memory can be accessed with read/write operations once it is initialized. Read/write operation can be performed with AHB access using the functions BSP_QSPI_Read()/BSP_QSPI_Write(). (++) The function BSP_QSPI_GetInfo() returns the configuration of the QSPI memory. (see the QSPI memory data sheet) (++) Perform erase block operation using the function BSP_QSPI_Erase_Block() and by specifying the block address. You can perform an erase operation of the whole chip by calling the function BSP_QSPI_Erase_Chip(). (++) The function BSP_QSPI_GetStatus() returns the current status of the QSPI memory. (see the QSPI memory data sheet)
