数字温度显示器源代码，用于显示DS18B20传感器传送过来的数据。(The digital temperature display source code for display the DS18B20 sensor data sent over.)

说明：  用C语言编写STM32嵌入式程序，设计一个万年历系统，并用HX1230屏显示相关的时间信息。 基本要求： 1.C语言程序要求是模块化设计。 2.该万年历要求能显示时间（时、分、秒）、年月日及闹钟定时时间（分、秒）。 3.该系统由2-3个按键可调整显示的时间、年月日及闹钟定时时间，具体各个按键功能及编程方式自定。 4.该闹钟可以定时时间到，LED将发出提示闪光，且持续30s。 5.HX1230屏能驱动显示。 6.定时时间可被打断，即打断后恢复时继续计时。 7.设置闹钟报警功能； 8.利用STM32自带的温度传感器功能，使系统能显示当前环境温度值。(STM32 embedded program is written in C language, a calendar system is designed, and relevant time information is displayed on HX1230 screen. Basic requirements: 1. The requirement of C language program is modular design. The calendar requires that time (hours, minutes, seconds), year, month, day and alarm clock timing time (minutes, seconds) be displayed. 3. The system can adjust the display time, year, month, day and alarm clock timing time by 2-3 keys, and the function and programming mode of each key are self-determined. 4. The alarm clock can be scheduled to arrive, and the LED will give a prompt to flash, and lasts for 30 seconds. 5. HX1230 screen can drive display. 6. Timing time can be interrupted, i.e. when the interruption is resumed, the timing will continue. 7. Setting alarm function of alarm clock; 8. Using the temperature sensor function of STM32, the system can display the current environmental temperature)

基于AVR的实时时钟芯片DS1302驱动程序开发， 在ATmega32下调试通过。(AVR-based real-time clock chip DS1302 driver development, debugging adopted under the ATmega32.)

51单片机读取AD7705的C程序，采用STC89C52单片机(51 MCU reads the AD7705' s C program, using STC89C52 SCM)

VB 开发C51的动态链接库，可以拿来直接用的，(VB-C51 dynamic link library that can be used directly, and)

说明：  带接收和发送协议处理的串口调试工具，可只接收并显示自定义关键字的串口数据，非常好用，带这种功能的可用的此类软件不多，值得收藏。(ComFilter,can receive and display your expired information from COM.)

说明：  本实验将实现如下功能：开机的时候先检测SD卡和SPI FLASH是否存在，如果存在则获取其容量，并显示在LCD上面（如果不存在，则报错）。之后开始USB配置，在配置成功之后就可以在电脑上发现两个可移动磁盘。我们用DS1来指示USB正在读写，并在液晶上显示出来，同样，我们还是用DS0来指示程序正在运行。(This experiment will achieve the following functions: when booting, first detect the existence of SD card and SPI FLASH, and if there is, obtain its capacity, and display it on the LCD (if not, report an error). Then the USB configuration is started, and after the configuration is successful, two removable disks can be found on the computer. We use DS1 to indicate that the USB is reading and writing, and display it on the LCD. Similarly, we use DS0 to indicate that the program is running.)
