Detailed Description

Connect external SDRAM to STM32F4xx devices with integrated FMC peripheral - http://stm32f4-discovery.com/2014/05/library-14-working-with-sdram-on-stm32f429-discovery/.

This library allows you to connect and use external SDRAM.

It supports 2 STM32F4 boards:

STM32F429-Discovery:
- 8MB (64Mbit) memory size
STM324x9-EVAL:
- 8MB (64Mbit) memory size

Set your target

By default, STM32F429-Discovery configuration is used, because this board is cheap and most users uses this.

If you are working with STM324x9-EVAL board, you can add define in defines.h file and enable configuration for SDRAM on this board.

//Use SDRAM on STM324x9-EVAL board
#define SDRAM_USE_STM324x9_EVAL
