前言
目前网上windows仿真freertos的资料都是比较久远的,不太适合现有的开发,因此重新整理了一下资料.
目标:
使用Vscode进行FreeRTOS开发和仿真.
关键词: freertos, vscode,llvm,cmake,windows
环境配置
编译器目前使用的是llvm-MinGW-msvcrt:Releases · mstorsjo/llvm-mingw (github.com)
FreeRTOS使用的最新版20240601-LTS:Release 202406.01-LTS · FreeRTOS/FreeRTOS-LTS (github.com)
Vsocde就常用的插件,这里调试用的codeLLDB,自己下载下.
编译器下载了加入环境变量,这里就不细说了
代码解压后,这里只关注FreeRTOS-Kernel
代码编译
使用code打开FreeRTOS-Kernel\examples\cmake_example,使用cmaketools正常配置,选择windows能用的编译器即可.
然后需要配置windows的port.c. 之前移植时需要自己加入编译目录,现在可以直接在Cmakelists.txt中配置.
# Select the heap port. values between 1-4 will pick a heap.
set(FREERTOS_HEAP "4" CACHE STRING "" FORCE)# Select the native compile PORT
set(FREERTOS_PORT "MSVC_MINGW" CACHE STRING "" FORCE)
修改成MSVC_MINGW
然后还要修改编译器设置
# Suppressions required to build clean with clang.$<$<COMPILE_LANG_AND_ID:C,Clang>:-Wno-unused-macros>$<$<COMPILE_LANG_AND_ID:C,Clang>:-Wno-padded>$<$<COMPILE_LANG_AND_ID:C,Clang>:-Wno-missing-variable-declarations>$<$<COMPILE_LANG_AND_ID:C,Clang>:-Wno-covered-switch-default>$<$<COMPILE_LANG_AND_ID:C,Clang>:-Wno-extra-semi-stmt>$<$<COMPILE_LANG_AND_ID:C,Clang>:-Wno-unsafe-buffer-usage>$<$<COMPILE_LANG_AND_ID:C,Clang>:-Wno-missing-noreturn>$<$<COMPILE_LANG_AND_ID:C,Clang>:-Wno-cast-align> )
不然会报错
然后就可以编译运行了
这里在main.c里修改一些代码
static void exampleTask( void * parameters )
{/* Unused parameters. */( void ) parameters;for( ; ; ){printf("example test\r\n");/* Example Task Code */vTaskDelay( 100 ); /* delay 100 ticks */}
}
运行结果:
."FreeRTOS-Kernel/examples/cmake_example/build/example.exe"
Example FreeRTOS Project
example test
example test
example test
example test
example test
调试
新建launch.json
加入以下代码
{"version": "0.2.0","configurations": [{"name": "windows","type":"lldb","request": "launch","program": "${command:cmake.launchTargetPath}",//通过cmake获取可执行文件名"args": [],"cwd": "${workspaceFolder}",},]
}
然后就可以调试了
