自学stm32f429xx系列芯片，写的位带操作程序，本人菜鸟级，只供参考，有什么纰漏望指正。。。。。。(I learned stm32f429xx series chip by myself, write the bit-band operation program, I am a rookie class, for reference only, what is wrong to look forward to correct)

stm32f429xx DMA串口接收IDLE中断 已调通(Stm32f429xx DMA serial port to receive IDLE interrupt has been transferred)

stm32F429XX 利用dma模块发送数据到gpio，稍加改动可以实现dma采集gpio程序。(Stm32F429XX use DMA module to send data to GPIO, a little change, you can achieve DMA acquisition GPIO program)
