OV7725摄像头循迹图像处理

51单片机采集PT100温度信息，采用ADS1247AD采集模块采集传感器电压，采用算法计算温度值，并利用PID算法控制设定温度大小，温控器件为可控过控制加热丝； 并采用lcd1602液晶显示当前温度与设定温度值；(51 single-chip PT100 temperature information acquisition module using ADS1247AD sensor voltage, using the algorithm to calculate the temperature value, and use the PID algorithm to control the temperature set size, temperature control device for controllable heating wire; LCD1602 LCD is used to display the current temperature and the setting temperature;)

stm32主控芯片实现对T5557卡的读写，资料包括读卡电路，T5557卡片的相关技术文档，上位机及工程源码。(The main control chip of STM32 realizes the reading and writing of T5557 card, including the reading circuit, the related technical documents of T5557 card, the host computer and the engineering source code.)

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)
