起步(开启C 支持)

CubeMX v6.1.0、RT-Thread Nano v3.1.3、Keil v5.33

第一步 配置并生成代码

官方指南假设你已了解关于CubeMX 的中级知识。如果你刚开始学习单片机，将此文档作为你的第一步可能不是最好的主意——掌握好基础知识再来吧！之前有其它框架的使用经验会有帮助，但这不是必需的。
配置好我们所需的外设后，添加CJSON、RTT支持包，如下图所示：

一定要去掉下面4项：

进行上一步操作之后，生成代码【GENERATE CODE】，此时用keil打开工程并进行相关设置，如下图：

第二步 安装nodejs、并添加相应支持

nodejs v14.15.1 LTS
添加脚本【${project}/MDK-ARM/RttSrcModify.js】

var fs = require('fs');
var path = require('path');
let log = console.log
const dir = fs.readdirSync('.');
let projectName = dir.filter(e=>e.includes('.uvprojx'))[0];
// log(projectName)
// return;
let ModifyKeilFilesConfigFilePath = path.join(__dirname, "RttSrcModify.json")
let defaultPath = '../Middlewares/Third_Party/RealThread_RTOS_RT-Thread'
let config = fs.readFileSync(ModifyKeilFilesConfigFilePath);
config = config.toString();
config = config.replace(/_myProject.uvprojx/g, projectName)
config = JSON.parse(config)
config?.modifyFiles?.forEach(e => {
  let fPath = e.filePath.includes('./') ? path.join(__dirname, e.filePath) : path.join(__dirname, defaultPath, e.filePath)
  let fileContent = fs.readFileSync(fPath)
  fileContent = fileContent.toString().split('\n');
  let isModify = false
  fileContent.forEach((ee, i) => {
    if (ee.includes(e.findStr)) {
      if(fileContent[i + e.dstOffset].includes(e.src)) {
       isModify = true;
       fileContent[i + e.dstOffset] = fileContent[i + e.dstOffset].replace(e.src, e.dst)
      }
    }
  })
  //log(fileContent)
  if(isModify) fs.writeFileSync(fPath, fileContent.join('\n'))
});

添加修改json文件【${project}/MDK-ARM/RttSrcModify.json】

{
  "modifyFiles":[
    {
      "filePath": "./_myProject.uvprojx",
      "findStr":"<FileName>main.c</FileName>",
      "dstOffset": 1,
      "src":"<FileType>1</FileType>",
      "dst":"<FileType>8</FileType>"
    },
    {
      "filePath": "./_myProject.uvprojx",
      "findStr":"<FileName>context_rvds.S</FileName>",
      "dstOffset": 1,
      "src":"<FileType>1</FileType>",
      "dst":"<FileType>2</FileType>"
    },
    {
      "filePath": "src/ipc.c",
      "findStr":"mb->msg_pool   = msgpool;\n",
      "dstOffset": 0,
      "src":"mb->msg_pool   = msgpool;\n",
      "dst":"mb->msg_pool = (rt_uint32_t *)RT_KERNEL_MALLOC(mb->size * sizeof(rt_uint32_t));\n"
    },
    {
      "filePath": "src/ipc.c",
      "findStr":"mb->msg_pool = RT_KERNEL_MALLOC(mb->size * sizeof(rt_uint32_t));\n",
      "dstOffset": 0,
      "src":"mb->msg_pool = RT_KERNEL_MALLOC(mb->size * sizeof(rt_uint32_t));\n",
      "dst":"mb->msg_pool = (rt_uint32_t *)RT_KERNEL_MALLOC(mb->size * sizeof(rt_uint32_t));\n"
    },
    {
      "filePath": "src/kservice.c",
      "findStr":"for (su1 = cs, su2 = ct; 0 < count; ++su1, ++su2, count--)\n",
      "dstOffset": 0,
      "src":"for (su1 = cs, su2 = ct; 0 < count; ++su1, ++su2, count--)\n",
      "dst":"for (su1 = (const unsigned char *)cs, su2 = (const unsigned char *)ct; 0 < count; ++su1, ++su2, count--)\n"
    },
    {
      "filePath": "src/thread.c",
      "findStr":"(void *)((char *)thread->stack_addr + thread->stack_size - 4),\n",
      "dstOffset": 0,
      "src":"(void *)((char *)thread->stack_addr + thread->stack_size - 4),\n",
      "dst":"(rt_uint8_t *)((char *)thread->stack_addr + thread->stack_size - 4),\n"
    },
    {
      "filePath": "include/rtdef.h",
      "findStr": "RT_USED const init_fn_t __rt_init_##fn SECTION(\".rti_fn.\"level) = fn\r",
      "dstOffset": 0,
      "src":"RT_USED const init_fn_t __rt_init_##fn SECTION(\".rti_fn.\"level) = fn\r",
      "dst":"RT_USED const init_fn_t __rt_init_##fn SECTION(\".rti_fn.\" level) = fn\r"
    },
    {
      "filePath": "bsp/rtconfig.h",
      "findStr": "#define RT_MAIN_THREAD_STACK_SIZE     256",
      "dstOffset": 0,
      "src":"#define RT_MAIN_THREAD_STACK_SIZE     256",
      "dst":"#define RT_MAIN_THREAD_STACK_SIZE     2048"
    },
    {
      "filePath": "bsp/rtconfig.h",
      "findStr": "//#define RT_USING_HEAP\r",
      "dstOffset": 0,
      "src":"//#define RT_USING_HEAP\r",
      "dst":"#define RT_USING_HEAP\r"
    },
    {
      "filePath": "bsp/board.c",
      "findStr": "#define RT_HEAP_SIZE 1024\r",
      "dstOffset": 0,
      "src":"#define RT_HEAP_SIZE 1024\r",
      "dst":"#define RT_HEAP_SIZE 1024 * 20"
    }
  ]
}

第三步 添加快捷菜单项

完成后，即可进行点灯啦！

当日总结

主线程栈默认值点灯都跑不起来【#define RT_MAIN_THREAD_STACK_SIZE 256】。
启用动态堆【#define RT_USING_HEAP】之后可以动态创建线程，但是线程栈总大小被【#define RT_HEAP_SIZE 1024】限制了，所以简单调节一下即可。
