MINISTM32-SPI

51环境的超声波程序，keil直接完美运行，需要复制到程序中(51 microcontroller ultrasound procedure can be run directly keil)

基于ARM的俄罗斯方块设计，本次将设计实现一个用C语言编写的、在基于ARM核心的ADuC7020 ARM开发板上实现的单机版的俄罗斯方块小游戏。使用Keil3编程软件对C语言代码进行编写，支持按键操作，在实现过程中涉及了LCD液晶屏的图形显示、按键控制、LED控制、中断、蜂鸣器等嵌入式的编程技术。(Tetris ARM-based design, this will be designed to achieve a C language, the ADuC7020 ARM development board ARM core-based implementations of stand-alone version of the Tetris game. Use Keil3 programming software code written in the C language, support for key operations involved in the implementation process of the LCD screen graphical display, control buttons, LED control, interrupt, buzzer embedded programming techniques.)

自行车的里程表。基于51单片单片机最小系统开发的(The bike' s odometer. Developed based on 51 single-chip microcontroller minimum system)

说明：  一个很通用的按键扫描程序，可用于单片机控制中(A very common key scanner can be used in the SCM)

智能车PID控制，非常不错的讲述PId原理的文献(Smart car PID control, very good about the principles of literature PId)

对ad7685的详细运用。加上12864显示。有电路图、芯片资料(Detailed use of ad7685 plus 12864 shows)

哈尔滨芯明天科技XE517系列压电陶瓷控制器配套上位机软件的开发例程，这个版本是VC6开发。发布时需要拷贝debug目录中的头文件和动态库文件到*.exe文件目录中。(Harbin XMT XE517 series of piezoelectric ceramic controller supporting PC software development routines, this version is VC6 development. When you need to copy the directory publishing debug header files and dynamic library files to*. Exe file directory.)

通过RS485端口不停地发送数据0xaa用示波器观察RS485端口A、B信号线上的波形或者用RS485接收器接收发送的字符。(Through the RS485 port to send data continuously 0xaa observed with an oscilloscope RS485 ports A, B signal waveforms or use the RS485 line receiver sends characters.)

西南交通大学图形学实验的第二个，响应键盘的系统键和非系统键(Second, the system in response to keyboard keys and key non-system experiments Southwest Jiaotong University Graphics)

红外报警程序，利用红外发射实现自动报警，当有目标靠近，发出蜂鸣名声(Infrared alarm program)
