Nand_demo
- 控制nand flash的演示框架，可自行填写代码，clk始终不超过100MHz-Control nand flash presentation framework should fill in the code, clk always less than 100MHz
low-pulse-triggered
- 在方式2计数期间，OUT端为高，当减到0，OUT端输出低脉冲。本实验用此低脉冲触发微控制器的中断。方式3是方波发生器方式，计数值N为偶数时，输出为对称方波，前N/2期间，OUT输出为高，后N/2期间，OUT为低。本实验中，时钟CLK信号由ALE接入，设Q0为输出频率，Q1为ALE频率，则：计算初值=Q1/Q0.-During the counting mode 2, OUT terminal is high, when reduced to 0, OUT-ended output low pul
SD-Card
- STM32F4xx has internal SDIO peripheral to work with SD cards. Also, SDIO communication is faster than SPI, but if you don’t need speed in your project, you can use SPI aswell. With default settings, SDIO 4-bit mode communication is used. It means, th
