stm32_adafruit_sd.c File Reference

This file provides a set of functions needed to manage the SD card mounted on the Adafruit 1.8" TFT LCD shield (reference ID 802), that is used with the STM32 Nucleo board through SPI interface. It implements a high level communication layer for read and write from/to this memory. The needed STM32XXxx hardware resources (SPI and GPIO) are defined in stm32XXxx_nucleo.h file, and the initialization is performed in SD_IO_Init() function declared in stm32XXxx_nucleo.c file. You can easily tailor this driver to any other development board, by just adapting the defines for hardware resources and SD_IO_Init() function. More...
