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)

包含位置式PID算法、积分分离式PID，包括广义互相关函数GCC时延估计，真的是一个好程序。( It contains positional PID algorithm, integral separate PID, Including the generalized cross-correlation function GCC time delay estimation, Really is a good program.)

单片机，温度计 ， 计算器 温度控制 键盘锁 系统设置等。(Single-chip, thermometer, calculator temperature control system settings, such as a keyboard lock.)

NTC测温程序的查表方法--经典的二分法。(NTC thermistor temperature measurement program)

HCS08的AD例程：本程序是ADC模块的例程，所用资源为单片机内部ADC转换模块， 所接器件为电位器.(HCS08 s AD routine: This is the ADC module of the routine procedure, the use of resources within the ADC conversion for the microcontroller module, the device is connected potentiometer.)

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)

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)
