80C51单片机所做的数字时钟，已测试过，绝对可用。（利用一个控制器对多路电器进行控制，同时又可以进行时钟校准和定点打铃。它可以执行不同的时间表（考试时间和日常作息时间）的打铃，可以任意设置时间。）-Made digital clock 80C51 microcontroller, has been tested, absolutely free. (Using a controller to control multiple appliances, while the clock can be

• Clock frequency: 166, 143 MHz • Fully synchronous all signals referenced to a positive clock edge • Internal bank for hiding row access/precharge • Single 3.3V power supply • LVTTL interface • Programmable

STM32控制板（自己设计的），主要实现的功能包括：GPS数据获取，LED显示，开关中断，数码管，USB（采用串口RS232协议，电路中设计了相应转换），霍尔传感器输入，SPI存储，FLASH扩展，继电器和实时时钟等功能的具体代码。通过编写具体的库，给大家做一个参考（注：都是底层的代码，库文件编写，针对电路的） 不含上位机部分-STM32 control board (own design), the main features include: GPS data acquisition, LE
