用汇编语言实现了精确频率计。实验已经通过-Using assembly language to achieve a precise frequency meter. Experiment has been passed

常用EEPROM芯片的读写操作，51单片机控制电路，实验时要用74LS373一片，AT28C16一片，AT28C17一片，电路十分简单，根据实际电路联接情况，自行确定存储地址，最后别忘了还要8个LED和470欧姆电阻.-EEPROM chip used to read and write operations, 51 MCU control circuit, experiment, use 74LS373 1, AT28C16 1, AT28C17 1, the circuit is very simple, based on the actual situation of the circuit connectivity, self-determined memory addresses, finally do not forget to also 8 LED and 470 ohm resistors.

基于arm的示波器设计，内含单片机控制外部驱动程序-Based on the arm of the embedded microcontroller control design, oscilloscope external driver
