说明：  用mcs-52系列单片机实现等精度频率测量，T1引脚接被测TTL信号，晶振22.1184MHz，对任何频率都可以实现很高精度的测量（精度<1 )，结果从串口字符串输出，波特率115200，可以用串口调试器观察结果.(With mcs-52 family of single chip and other precision frequency measurement, T1 pin then measured TTL signal, Crystal 22.1184MHz, any frequency can be achieved very high accuracy of measurement (precision<1 ), the result string from the serial output , baud rate 115200, serial debugger can observe the results.)

基于EFM32G890F128的IIC读写外部EEPROM器件24AA024的工程文件。(Based EFM32G890F128 IIC reading external EEPROM device project file 24AA024' s.)

用138,595控制的点阵，附带两个不同控制方式的源程序以及电路连接图，(With 138,595 dot control, with two different control modes of the source and a circuit connection diagram,)

最小的单片机PWM控制，电压控制PWM输出，智能化，体积小。(ADC control PWM output)

单片机AD功能实例，使用1602显示电压(SCM AD function example, the use of 1602 shows the voltage)

刚才上传的频率计程序可能不太好，现在这个计数外部脉冲的程序，还是较好的，只是得自己从中截取出来(Just upload the program may not be a good frequency counter, and now this external pulse count procedures, or better, just get yourself out from the interception of)
