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. )

这是一个楼禁门宇系统的程序，经过调试仿真，结果良好，但是有待改进(This is a building ban door-yu system procedures, after debugging emulator with good results, but could be improved)

实现对模拟量的数字化 ADC (Analog to Digital Converter) 中文译名: 模数变换器 分类: IP与多媒体 解释: 将连续变量的模拟信号转换为离散的数字信号的器件。(analog to digital Analog to Digital Converter)

说明：  根据stm32f103自带DA功能和DMA实现输出正弦波,可根据改变定时器周期改变正弦波频率。(According to the DA function and DMA of stm32f103, the output sinusoidal wave can be realized, and the frequency of sinusoidal wave can be changed according to the period of timer.)

此程序是基于stc单片机的2.2寸串口屏的控制程序，驱动芯片为ILI9341.(This procedure is based on stc SCM 2.2-inch screen serial control program, driver chips for ILI9341.)

说明：  可以在电脑里生成2个VCP口，具体如何操作这两个VCP口，我还没搞清楚。(Two VCP ports can be generated in the computer)
