GD32电磁循迹小车代码

GD32电磁循迹小车是一种基于GD32微控制器的智能小车，它可以通过电磁感应模块来实现自动循迹功能。下面是一个简单的GD32电磁循迹小车代码示例：

#include <gd32f30x.h>

#define LEFT_SENSOR_PIN GPIO_PIN_0
#define RIGHT_SENSOR_PIN GPIO_PIN_1

void delay(uint32_t count)
{
    for(uint32_t i = 0; i < count; i++);
}

void init_gpio(void)
{
    rcu_periph_clock_enable(RCU_GPIOA);
    gpio_init(GPIOA, GPIO_MODE_IN_FLOATING, GPIO_OSPEED_50MHZ, LEFT_SENSOR_PIN | RIGHT_SENSOR_PIN);
}

int main(void)
{
    init_gpio();
    
    while(1)
    {
        uint8_t left_sensor = gpio_input_bit_get(GPIOA, LEFT_SENSOR_PIN);
        uint8_t right_sensor = gpio_input_bit_get(GPIOA, RIGHT_SENSOR_PIN);
        
        if(left_sensor && right_sensor) // both sensors on the line
        {
            // move forward
            // your code here
        }
        else if(left_sensor && !right_sensor) // only left sensor on the line
        {
            // turn right
            // your code here
        }
        else if(!left_sensor && right_sensor) // only right sensor on the line
        {
            // turn left
            // your code here
        }
        else // both sensors off the line
        {
            // stop
            // your code here
        }
        
        delay(100000); // delay for a while before next reading
    }
}

这段代码使用了GD32的GPIO模块来读取电磁感应模块的输出信号。根据左右传感器的状态，可以实现小车的前进、转向和停止等功能。你可以根据具体的硬件连接和需求，编写相应的代码来控制小车的动作。
