基于STM32的示波器的完整程序与硬件，可以显示波的各种参数，和真实示波器一样。(The complete program and hardware of Oscilloscope Based on STM32 can display various parameters of wave, just like real oscilloscope.)

74164串行口转并行口芯片驱动模块，使用EMC系列单片机(74164 serial port to parallel port chip driver module, using EMC Series MCU)

新唐nano100参考示例代码，很有参考价值 (New tang nano100 reference sample code, is of great reference value)

LPC1788普通IO口中断,很好用的一个例程，之前弄了好久才弄明白。(GPIO interuper you know why I can you love me yes NO hello)

Wireless Channel Simulator Testbed for Airborne Receivers

PWM调光 1、学习目的：利用定时器产生PWM，了解原理和使用方法 2、硬件要求：LED灯 定时器 3、试验现象：LED灯由亮到灭，由灭到亮逐步变化，也就是调光现象(PWM dimming, learning objectives: the use of the timer to generate PWM understand the principles and use hardware requirements: LED lamp timer test phenomenon: LED lights from bright to off, gradually changes from off to bright, that is, adjusted optical phenomena)

1.由上位机发送1给单片机时，蜂鸣器以400ms频率发声，发2时以200ms频率发声，发3时以100ms频率发声，发4时关闲蜂鸣器。 1.以2400bps从计算机发送任一字节数据，当单片机收到该数据后，在此数据前加上一序号然后连同此数据一起发送至计算机，当序号超过255时归零。 2.以16进制发送一个0-65536之间的任一数，当单片机收到后在数码管上动态显示出来，波特率自定。 3. 用AD以1HZ的频率采集模拟信号，然后转换成数字量，再将其以1200bps发送到计算机，在计算机上显示。 4.按下矩阵键盘第一行时以1200bps发送，1，2，3，4，第二行时以2400bps发送5，6，7，8，第三行以4800bps发送，9，10，11，12，第四行以9600pbs 发送，13，14，15，16. (1. From the PC to send a single chip, the buzzer to 400ms frequency of sound, made 2 to 200ms frequency sound, made from 3 to 100ms frequency sound, made 4 free buzzer off. 1. To 2400bps from the computer to send any byte of data, when the microcontroller receives the data in this data with a serial number before then sent along with the data to the computer, the serial numbers when more than 255 zero. 2. To send a 16-hexadecimal any number between 0-65536, when the microcontroller in the digital receipt is displayed on a dynamic, custom baud rate. 3. 1HZ with the frequency of AD in order to capture analog signals, then converted to digital, and then send it to 1200bps to the computer, the computer display. 4. Press to 1200bps matrix keyboard to send the first row, 1,2,3,4, 5,6,7,8 the second row to 2400bps send the third line to 4800bps send, 9,10,11,12 , the fourth line to 9600pbs send, 13,14,15,16. )

说明：  本程序用作pid控制，不过基于AVR硬件乘除法，移植性不高，本人是作者。(the procedures for pid control, but based on the hardware AVR calculation method, transplantation is not high, is the author.)

7279的程序 是在lpc2138上的经过调试绝对好使(7279 program in lpc2138 absolutely so on through the commissioning)
