精心收集整理的STM32F4XX全系列原理图封库,相当齐全。

STM32F4xx 系列固件库，看到还有很多人找，传上来方便大家。

Keil.STM32F4xx_DFP.2.13.0,keil STM32F4xx版本芯片支持包

STM32F4XX STM32F4XX STM32F4XX STM32F4XX固件库之 DSP DSP DSP DSP库的说明 为了充分发挥 STM32F4XX（Cortex-M4F）处理器浮点运算性能，建议使用固件库自带的 arm_math.h 头文件而非编译器自带的math.h。此文件位于\Libraries\CMSIS\Lib 文件夹。 硬件准备： 需要开启 STM32F4XX 的 FPU

stm32f4xx挂载SD卡程序，可以正常读写

针对 STM32F4xx 的内部flash的读写操作，经本人优化，运行稳定可靠。
