测试C++代码：

#include <Arduino.h>

#define LED_D4 12
#define LED_D5 13

void setup()
{
  // put your setup code here, to run once:
  Serial.begin(115200);
Serial.println("
ESP32-C3 starts!");
pinMode(LED_D4, OUTPUT);
  pinMode(LED_D5, OUTPUT);
}

void loop()
{
  // put your main code here, to run repeatedly:
  Serial.println("My First PIO Project!");

  delay(1000);
  digitalWrite(LED_D4, HIGH); // 点亮D4
  digitalWrite(LED_D5, LOW);  // 熄灭D5
  delay(2000);
  digitalWrite(LED_D4, LOW);  // 熄灭D4
  digitalWrite(LED_D5, HIGH); // 点亮D5
  delay(2000);
  Serial.println("end----------!");
}
