GD32F303RCT6电磁循迹代码

GD32F303RCT6是一款基于ARM Cortex-M4内核的微控制器，适用于电磁循迹等应用。以下是一个简单的GD32F303RCT6电磁循迹代码的示例：

#include "gd32f30x.h"

#define SENSOR_NUM 5
#define THRESHOLD 1000

uint16_t sensorValues[SENSOR_NUM];

void setup() {
    // 初始化IO口和ADC模块
    rcu_periph_clock_enable(RCU_GPIOA);
    rcu_periph_clock_enable(RCU_ADC0);
    gpio_init(GPIOA, GPIO_MODE_AIN, GPIO_OSPEED_50MHZ, GPIO_PIN_0 | GPIO_PIN_1 | GPIO_PIN_2 | GPIO_PIN_3 | GPIO_PIN_4);
    adc_mode_config(ADC_MODE_FREE);
    adc_special_function_config(ADC0, ADC_SCAN_MODE, ENABLE);
    adc_data_alignment_config(ADC0, ADC_DATAALIGN_RIGHT);
    adc_channel_length_config(ADC0, ADC_INSERTED_CHANNEL, SENSOR_NUM);
    adc_inserted_channel_config(ADC0, 0, ADC_CHANNEL_0, ADC_SAMPLETIME_239POINT5);
    adc_inserted_channel_config(ADC0, 1, ADC_CHANNEL_1, ADC_SAMPLETIME_239POINT5);
    adc_inserted_channel_config(ADC0, 2, ADC_CHANNEL_2, ADC_SAMPLETIME_239POINT5);
    adc_inserted_channel_config(ADC0, 3, ADC_CHANNEL_3, ADC_SAMPLETIME_239POINT5);
    adc_inserted_channel_config(ADC0, 4, ADC_CHANNEL_4, ADC_SAMPLETIME_239POINT5);
    adc_external_trigger_source_config(ADC0, ADC_INSERTED_CHANNEL, ADC0_1_EXTTRIG_INSERTED_NONE);
    adc_external_trigger_config(ADC0, ADC_INSERTED_CHANNEL, ENABLE);
    adc_calibration_enable(ADC0);
    adc_enable(ADC0);
}

void loop() {
    // 读取传感器值
    adc_software_trigger_enable(ADC0, ADC_INSERTED_CHANNEL);
    while(!adc_flag_get(ADC0, ADC_FLAG_EOC));
    for(int i = 0; i < SENSOR_NUM; i++) {
        sensorValues[i] = adc_inserted_data_get(ADC0, i);
    }
    
    // 判断循迹状态
    int sum = 0;
    for(int i = 0; i < SENSOR_NUM; i++) {
        sum += sensorValues[i];
    }
    if(sum > THRESHOLD) {
        // 循迹动作
        // ...
    } else {
        // 停止动作
        // ...
    }
}

int main(void) {
    setup();
    while(1) {
        loop();
    }
}

这段代码使用了GD32F303RCT6的ADC模块来读取电磁传感器的值，并根据阈值判断循迹状态。你可以根据具体的电磁传感器和循迹算法进行适当的修改。
