在淘宝上购买的毕业论文，价值400的源程序，包含全部文件。一款基于单片机的灭火机器人模型的设计。系统以STC89C52RC单片机为控制核心，创新自制了火焰传感器用来测量火源，使用TCRT5000型光电对管检测循迹黑线，L298驱动电机前后转动，LCD1602液晶显示灭火的次数，通过控制继电器开关风扇灭火。(On Taobao buy thesis, the value of the 400 source code, including all documents. Fire fighting robot model based on a single-chip design. System microcontroller STC89C52RC to control core, innovation homemade flame sensor is used to measure the fire source, tracking black line on the tube use TCRT5000 photoelectric detection, L298 drive motor rotating back and forth, the LCD1602 LCD number of fire-fighting, fire control relay switch fan .)

main.c已详尽注释连接的引脚 和 调试助手参数。STM32分别以串口,硬件SPI,模拟并口驱动CH395,4个socket连接, 原路返回上位机发送的数据。串口模式支持更改工作波特率，硬件SPI速率最高36MHz, 模拟并口较快，这三种模式支持在stm32任意型号下。(Main.c has commented on pins and debugging assistant parameters in detail. STM32 drives CH395 and 4 sockets by serial port, hardware SPI and analog parallel port respectively, and returns the data sent by the host computer in the original way. Serial mode supports changing working baud rate. Hardware SPI rate is up to 36MHz and analog parallel port is fast. These three modes support any model of stm32.)
