1820显示温度（LED(595)）C语言版 通过串口设定温度和读取当前温度(1820 shows that the temperature (LED (595)) C language version through the serial port settings to read the current temperature and temperature)

基于51单片机的信号发生器 四种波形显示 有级调频(Based on 51 single-chip signal generator)

利用PID算法控制PWM输出电压，实现串联型数控电源，通过键盘输入控制期望电压(PID algorithm to control the use of PWM output voltage to achieve tandem CNC power, through the keyboard input control voltage expectations)

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)

与沉默的开关为iOS，精选ios编程学习源码，很好的参考资料。(And the silence of the switch is iOS, select learning IOS programming source code, a good reference.)
