stm3210e_eval_serialflash.c File Reference

This file provides a set of functions needed to manage the SPI M25Pxx FLASH memory mounted on STM3210E_EVAL board. It implements a high level communication layer for read and write from/to this memory. The needed STM32 hardware resources (SPI and GPIO) are defined in stm3210e_eval.h file, and the initialization is performed in FLASH_SPI_IO_Init() function declared in stm3210e_eval.c file. You can easily tailor this driver to any other development board, by just adapting the defines for hardware resources and FLASH_SPI_IO_Init() function. More...
