利用DSPTMS320LF2407产生PWM波，其输出波形为方波(Produced by DSPTMS320LF2407 PWM wave, the output waveform is square wave)

用stm8硬件 I2C 中断方式 发送/接收数据， 经过查阅手册和反复验证，已经完成了，话不多说，上代码。(With stm8 hardware I2C interrupt mode to send / receive data, After reviewing the manual and repeated verification, has been completed, then not much on the code.)

这是一个用51单片机系统仿真ucosii工作的protues电路 本系统包括扩展64k RAM的单片机系统和杨屹移植到51单片机的ucosii 系统 使用方法： 1.安装Protues7.4版，然后用protues打开protues 8051 simulation 文件夹 中的extern ram.DSN 文件 2.打开extern ram.DSN 后，双击单片机在弹出的窗口中的Program File 选项 中选择yy.hex文件。 (yy.hex其实就是yy文件夹中keil文档编译出来的hex文 件，yy文件夹是杨屹的ucos51 系统，用keil 2 可以打开) 3.在Clock Frequency选项中输入22.184M(杨屹的ucos51 用的是22.184M hz的单片机频率) 4.双击VTERM串口调试显示屏，在Baud Rate 选项中选择19200的波特率 5.保存，点击运行就可以看到经典的hello world 了。 (1. Protues7.4 version installed, and then open the protues folder protues 8051 simulation The extern ram.DSN file 2. Open extern ram.DSN, double-click the pop-up window of SCM in the Program File option, select yy.hex file. (yy.hex actually yy folder keil out of the document compiled hex files, yy folder is Yang Yi s ucos51 system, using keil 2 Can open) 3. In the Clock Frequency option to enter 22.184M (Yang Yi of the ucos51 using a microcontroller 22.184M hz frequency) 4. Double-click VTERM serial debug display, in the Baud Rate select 19200 baud rate options 5. Save, click Run you can see the classic hello world)

用时钟芯片DS1302在LCD1602上实现显示时间(DS1302 clock chip used to achieve the LCD1602 display time )

说明：  单片机STM32103RCT6,GD32F103RCT6,程序管脚都兼容，采集16通道的ADC数据，通过FATFS文件管理系统将数据存储到SD卡。(Stm32103rct6 and gd32f103rct6 are single-chip computers. The program pins are compatible. The ADC data of 16 channels are collected and stored in SD card through FatFs file management system.)

说明：  使用单片机对蜂鸣器进行控制，要求蜂鸣器唱出《八月桂花》这首歌，简单加深对定时器的理解和蜂鸣器的应用，更深入的理解51的内部结构和使用方式。(The buzzer is controlled by single-chip computer, which requires the buzzer to sing the song "Osmanthus fragrans in August". It can simply deepen the understanding of timer and the application of buzzer, and further understand the internal structure and use mode of 51.)

STM8S105 实现多路的ADC采集，并且把其中的两路通过串口UART发送到电脑上。其中有通信方法RS232 说明和LabVIEW2010的上位机示波器。oscillograph(STM8S105 LabVIEW2010 UART RS232 oscillograph ADC Send.)

.提供一般的题目选择和控制相关功能函数的运行。 .支持在屏幕上直接调参，对参数具有断电保护，锁定保护的功能。 .未加入ucos操作系统（近年来电赛中还没有必要用到操作系统） .此文件针对stm32f103zet6开发板，提供底层的屏幕显示和操作控制功能，具体比赛要求的功能应自行写成单独的模块加入此文件中即可运行。(1. provides general topic selection and control of the function of the function. 2. supports the direct parameter adjustment on the screen, the power failure protection for the parameters and the function of locking the protection. 3. not added to the UCOS operating system (there is no need to use the operating system in recent caller calls) 4., this document provides the bottom screen display and operation control function for the stm32f103zet6 development board, and the function of specific match request should be written into a separate module by itself.)

说明：  LIS3DH通过IIC与cc2541单片机进行通讯(Lis3dh communicates with cc2541 through IIC)
