EPS32+Platform+Arduino 跑马灯

软硬件平台

硬件使用ESP32 D0WQ6，是在淘宝上购买的一个核心功能板，用做simplFOC的核心控制板。

软件平台使用Arduino，Arduino-ESP32有详细介绍ESP32针对arduino平台做的library和API接口

IDE软件采用PlatformIO，主要因为这个IDE比Arduino IDE的编译速度快很多。Arduino IDE简单易用，但是编译上传实在太慢，忍无可忍才找到了PlatforIO来替换

环境搭建

platformIO整个环境的搭建和使用已经有很多文章了，可以参考VSCode + PlatformIO + STM32/ESP32 ARDUINO。这里主要记录下测试跑马灯时的问题。具体程序可以看下节跑马灯程序及配置。

新建工程后，首次编译没有问题，首次点击 upload 提示Tool Manager: Installing platformio/tool-mkspiffs @ ~2.230.0，这里需要安装一系列的upload工具套件，必须关闭网络加速/代理，否则会一直停在这里，超时后会报错：终端将被任务重用 按任意键关闭。

我的环境需要安装的套件：

Installing platformio/tool-mkspiffs @ ~2.230.0
Installing platformio/tool-mklittlefs @ ~1.203.0
Installing platformio/tool-mkfatfs @ ~2.0.0

跑马灯程序及配置

跑马灯程序代码如下：

#include <Arduino.h>

#define LED 22
// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED as an output.
  pinMode(LED, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(500);                       // wait for a second
  digitalWrite(LED, LOW);    // turn the LED off by making the voltage LOW
  delay(500);                       // wait for a second
}

如下图点击上传后，platformio会进行编译，上传，过程提示如下
