Arduino IDE

• 选择 ESP32 Dev Module

• demo.ino

#define LED 2void setup() {pinMode(LED, OUTPUT);
}void loop() {digitalWrite(LED, HIGH);delay(500);digitalWrite(LED, LOW);delay(500);
}

• 编译后的文件所在目录

cd /private/var/folders/y3/m5gygl0x29qb6gqzwbzhnbl40000gn/T/arduino/sketches/7BF1D604324680D884686063EF3F4C75/

• 创建模拟器

• 生成 diagram.json 与 wokwi.toml 文件

• 修改 diagram.json 文件

}

VSCode 配置

安装 wokwi 插件

打开编译后目录

注： 选中 diagram.json 文件就会显示模拟器。

ESP32C3 示例

Arduino IDE

• demo.ino

#include <Arduino.h>void setup() {// put your setup code here, to run once:Serial.begin(9600); // 初始化串口通信
}void loop() {// put your main code here, to run repeatedly:Serial.println("Hello World!"); // 输出 "Hello World"delay(1000); // 等待 1 秒
}

注： 进入编译后的可执行文件目录

cd /private/var/folders/y3/m5gygl0x29qb6gqzwbzhnbl40000gn/T/arduino/sketches/7BF1D604324680D884686063EF3F4C75/
