安装客户端（Mac/Linux）

curl -L https://wokwi.com/ci/install.sh | sh

• 添加环境变量

export PATH="/usr/local/bin:$PATH"

创建 Token

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

{"version": 1,"author": "Uri Shaked","editor": "wokwi","parts": [{ "type": "wokwi-esp32-devkit-v1", "id": "esp", "top": 0, "left": 0, "attrs": {} },{"type": "wokwi-led","id": "led1","top": -3.33,"left": 153.33,"attrs": { "color": "red" }},{ "type": "wokwi-resistor", "id": "r1", "top": 64, "left": 149.33, "rotate": 90, "attrs": {} }],"connections": [[ "esp:TX0", "$serialMonitor:RX", "", [] ],[ "esp:RX0", "$serialMonitor:TX", "", [] ],[ "esp:GND.1", "led1:C", "black", [ "h0" ] ],[ "led1:A", "r1:1", "green", [ "v0" ] ],[ "r1:2", "esp:D2", "green", [ "h0", "v38" ] ]]
}

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/
