基于stm32开发的红外循迹小车

本项目算是接触32来开发的第一个小项目了，虽然前期用51写过一个循迹小车，以为直接转到32会比较简单，结果还是花了大几天才把小车的参数完全调完，以此来记录下自己的学习历程（注：循迹算法并未加入PID算法）

所需原件及其模块：

1.stm32c8t6最小系统板：

2.红外循迹模块（可以只用一个五路循迹模块，不需要单个的循迹模块，使用单个循迹模块是因为需要检测起始线（比赛题目要求））

五路循迹模块：

单个循迹模块：

3.车模底板：

4.L298N电机驱动模块（不能直接用单片机给电机供电，需要用一个驱动模块）：

5.TT马达（直流电机）：

6.面包板（便于插线，单片机的接口不够用的时候使用面包板可以很好的解决这个问题）：

7.0.96寸OLED屏：

具体介绍每个原件及模块的用法：

1.红外循迹模块：检测黑线的原理是向外发射红外线，当没有遇到黑线的时候，返回回来，之后返回高电平，当遇到黑线的时候，红外被吸收，返回高电平，读取相应IO口的电平就可以知道小车此时的大致位置；

2.L298N电机驱动模块：分别是5V，12V，GND，可以通过外加电源给驱动模块供电，IN1，IN2，IN3，IN4，EN1，EN2，通过给IN口不同的电平，可以达到控制电机正反转，EN口为使能口，可以通过给EN口不同的PWM波，来达到控制小车速度，模块有四个输入接口，分别连接四个TT马达，驱动小车运动；PWM波：通过定时器来控制占空比，从而达到宏观上控速的现象；

Trace.c:讲解一下循迹代码，就是当检测到某一个具体的状态时，需要小车做出相应的反应来维护小车始终在黑线上，比如，假设此时的状态为(!DET1 && DET2 && DET3 && DET4 && DET5)即红外循迹模块检测到电平为01111，则此时黑线在小车左边，需要快速将小车左转，则我们可以将小车的左轮向后转，右轮向前转，就可以很好的转向了，此外当小车速度过快的时候，可能刚检测到黑线的时候，由于小车没反应过来，车身已经冲出赛道了，我们可以另外用一个算法来维护，假设我们冲出赛道的时候是向左转，则一旦冲出赛道（即红外循迹模块电平为11111）此时可以持续小车左转的状态，直到小车自行转到赛道上，可以继续沿着赛道循迹，当然此方法只是没学PID算法的一种下策，并不能很流畅的解决所有赛道
