以hello-world为例，演示步骤和注意事项

1、新建ESP-IDF项目

选择模板

从hello-world模板创建

2、打开项目

3、编译结果没错

正在执行任务: /home/azhu/.espressif/python_env/idf5.1_py3.10_env/bin/python /home/azhu/esp/v5.1/esp-idf/tools/idf_size.py /home/azhu/ESP32/test/use_componet/build/use_componet.map Total sizes:
Used static DRAM:   10664 bytes ( 170072 remain, 5.9% used).data size:    8472 bytes.bss  size:    2192 bytes

Used Flash size :  118107 bytes.text:   80723 bytes.rodata:   37128 bytes
Total image size:  175537 bytes (.bin may be pa

4、烧写运行

5、添加组件，功能为再输出一行文字

COMMAND->Create ESP-IDF Compontent

最上方输入自己的组件名称然后回车，这里输入 mycomp

ESP-IDF自动创建compontents文件夹，然后在下面有mycomp文件夹，里面有mycomp.c，include/mycomp.h

编写代码，mycomp.c

#include <stdio.h>
#include "mycomp.h"void func(void)
{printf("call by mycomp\n");
}

main/hello_world_main.c，只加两行

......
#include "esp_flash.h"
#include "mycomp.h"        //addvoid app_main(void)
{......printf("Restarting now.\n");func();                //addfflush(stdout);

6、再次编译，不出意外的话，一定报错：

 ............../use_componet/main/hello_world_main.c
/home/azhu/ESP32/test/use_componet/main/hello_world_main.c:14:10: fatal error: mycomp.h: No such file or directory14 | #include "mycomp.h"|          ^~~~~~~~~~
compilation terminated.
ninja: build stopped: subcommand failed.

7、关键要点！

原因是main没有包含自己写的组件，或者说依赖，把main/CMakeLists.txt修改为

idf_component_register(SRCS "hello_world_main.c"INCLUDE_DIRS "")
改成如下：idf_component_register(SRCS "main.c"INCLUDE_DIRS ""PRIV_REQUIRES mycomp)

再编译，错误变了

/use_componet/main/hello_world_main.c:13:10: fatal error: esp_flash.h: No such file or directory13 | #include "esp_flash.h"|          ^~~~~~~~~~~~~
compilation terminated.
[902/910] Building C object esp-id...provisioning.dir/src/manager.c.obj
ninja: build stopped: subcommand failed.

继续修改main/CMakeLists.txt，右键点#include "esp_flash.h"，然后转到定义，可以看到esp_flash.h位于esp_flash模块，所以加上spi_flash组件

idf_component_register(SRCS "hello_world_main.c"INCLUDE_DIRS ""PRIV_REQUIRES spi_flash mycomp)

所有的include都有组件支持了，编译无错，运行后可以看到输出了 call by mycomp

I (331) main_task: Calling app_main()
Hello world!
This is esp32 chip with 2 CPU core(s), WiFi/BTBLE, silicon revision v3.0, 2MB external flash
Minimum free heap size: 301172 bytes
Restarting in 10 seconds...
......
Restarting in 0 seconds...
Restarting now.
call by mycomp
ets Jul 29 2019 12:21:46rst:0xc (SW_CPU_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
.....

8、如果自己的组件中不止一个源文件怎么办，方法是编辑组件根下的CMakeLists.txt，这里示例为components/mycomp/CMakeLists.txt，有两个方法可以组织源文件和头文件

file(GLOB_RECURSE SOURCES *.c */*.c)set(include_dirs """include"
)
idf_component_register(SRCS ${SOURCES}INCLUDE_DIRS ${include_dirs})# idf_component_register(SRCS "mycomp.c" "mycomp2.c"
#                     INCLUDE_DIRS "include")

这里简单示例，mycomp2.c和mycomp.c功能差不多，最后在主程序func();后面加了行func2();

运行结果：

I (331) main_task: Calling app_main()
Hello world!
This is esp32 chip with 2 CPU core(s), WiFi/BTBLE, silicon revision v3.0, 2MB external flash
Minimum free heap size: 301172 bytes
Restarting in 10 seconds...
....
Restarting in 0 seconds...
Restarting now.
call by mycomp
call by mycomp---2

9、小结

如果main模块编译出错，需要编辑同级CMakeLists.txt，如果组件编译出错，也要编辑同级CMakeLists.txt

如果需要，执行COMMAND->Full Clean
