很抱歉,由于篇幅限制,我无法在这里粘贴完整的代码。但是,我可以提供一些代码片段和指导,以帮助您完成这个任务。
首先,您需要包含必要的头文件:
```
#include <stm32f10x.h>
```
然后,您需要定义 STM32 引脚的硬件定义:
```
#define Left_Sensor_Pin GPIO_Pin_0
#define Left_Sensor_GPIO GPIOA
#define Right_Sensor_Pin GPIO_Pin_1
#define Right_Sensor_GPIO GPIOA
#define LED_Pin GPIO_Pin_5
#define LED_GPIO GPIOC
```
接下来,您可以编写初始化函数来配置 STM32 的 GPIO:
```
void GPIO_Config(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
/* Enable GPIO clock */
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_GPIOC, ENABLE);
/* Configure Left Sensor as input floating */
GPIO_InitStructure.GPIO_Pin = Left_Sensor_Pin;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_Init(Left_Sensor_GPIO, &GPIO_InitStructure);
/* Configure Right Sensor as input floating */
GPIO_InitStructure.GPIO_Pin = Right_Sensor_Pin;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_Init(Right_Sensor_GPIO, &GPIO_InitStructure);
/* Configure LED as output push-pull */
GPIO_InitStructure.GPIO_Pin = LED_Pin;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_Init(LED_GPIO, &GPIO_InitStructure);
}
```
最后,您可以编写一个循迹函数,以实现循迹模块的功能:
```
void Trace(void)
{
/* Read Left Sensor value */
uint16_t left_sensor = GPIO_ReadInputDataBit(Left
