麒麟银河V10 SP1 配置 Visual Studio Code

#esp32-c3

华为擎云W515X用了几天，兼容性问题愈发严重，于是换了一台中科的T40D，处理器是海光C86-3G，独显为 Glenfly Arise 1020 ，解码终于正常了。搭配16GB DDR4内存 + 512GB固态 + 2T 机械硬盘目前体验良好，于是来学习编程吧。

IDE首选Visual Studio Code，可以在应用商店中一键安装，也可以到微软官网下载，x86架构不存在兼容性问题。

用C语言写hello world

在使用C语言写hello world前，记得先安装gcc、gdb、make等工具链，避免出现奇怪的错误。当年学习C语言时用的还是Visual C++ 6.0，后来写C#时候用的Visual Studio 2010，它们和现在的Visual Studio Code差别很大。前者自身就是完整开发环境，而Visual Studio Code更类似于一个浏览器，各种功能以插件形式存在，安装配置灵活，拓展性极强，缺点无法开箱即用。新手可以观看这个视频入门：Visual Studio Code for C/C++ on Linux (2021)

简单来说在Visual Studio Code中用C语言写hello world并编译运行需要这几个步骤：

  1. 在linux系统中安装工具链；

  2. 在Visual Studio Code中安装C/C++ 插件；

  3. 在Visual Studio Code添加文件夹。Visual Studio Code以文件夹为单位组织代码，需要注意；

  4. 在Visual Studio Code添加文件，撰写代码，按照提示生成launch.json与tasks.json，并酌情修改。

安装配置PlatformIO

PlatformIO据说比Arduino IDE更灵活、功能更强大。 安装拓展之前，首先安装Python依赖：

sudo apt install python3-venv

然后再安装PlatformIO即可。

在 PIO Home选择Embedded，搜索安装目标平台。我安装了 Raspberry Pi RP2040、Espressif 32和Nordic nRF52，它们每一个都包含了数量众多的开发板和开发示例。

回到PIO Home，选择Project Examples导入示例项目即可测试。比如Espressif 32的arduino-blink，这一阶段会一并下载工具链、SDK、framework等，需要耐心等待。

/*
 * Blink
 * Turns on an LED on for one second,
 * then off for one second, repeatedly.
 */

#include <Arduino.h>

// Set LED_BUILTIN if it is not defined by Arduino framework
#ifdef LED_BUILTIN
    #undef LED_BUILTIN
#endif

#ifndef LED_BUILTIN
    #define LED_BUILTIN 8
#endif

void setup()
{
  // initialize LED digital pin as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop()
{
  // turn the LED on (HIGH is the voltage level)
  digitalWrite(LED_BUILTIN, HIGH);
  // wait for a second
  delay(1000);
  // turn the LED off by making the voltage LOW
  digitalWrite(LED_BUILTIN, LOW);
   // wait for a second
  delay(1000);
}

PlatformIO的ESP32库没有包含ESP32-C3 Supermii这个开发板，不过可以借用现成的lolin_c3_mini。注意需要修改板载LED对应的PIN脚。

编译时请点击左下角的“√”，也可以使用快捷键：

  • ctrl+alt+b / cmd-shift-b / ctrl-shift-b Build Project

  • cmd-shift-d / ctrl-shift-d Debug project

  • ctrl+alt+u Upload Firmware

  • ctrl+alt+s Open Serial Port Monitor

注意，用快捷键可能会唤出多个build选择项，请选择 PlatformIO: Build 。首次构建可能没有这个选项，可以手动输入，或者点击左下角的“√”，构建过一次后下次就有了。

该项目Platformio.ini文件内容如下：

[env:adafruit_qtpy_esp32s3_n4r2]

直接build会生成Platformio.ini中所有开发板的程序，upload同理。可以参考项目文件中的README，仅构建并上传lolin_c3_mini配置程序：

$ pio run -e lolin_c3_mini -t upload
