Esp32 construction engineering add components

One 、 Top level documents CMakeList.txt

# The following lines of boilerplate have to be in your project's
# CMakeLists in this exact order for cmake to work correctly
cmake_minimum_required(VERSION 3.5)

include($ENV{
    IDF_PATH}/tools/cmake/project.cmake)

project(3_4_lcd) The project name here is to copy other people's components , Except that the project name is modified by itself, the others remain unchanged 

• Component files CMakeList.txt
• Whether it's app_main.c Or do other components need CMakeList.txt

Two 、 Component files CMakeList.txt

idf_component_register(SRCS "Lcd.c" 
                    // Under components .c File name 
                    INCLUDE_DIRS "."
                    // Under the current file directory 
                    REQUIRES driver)
           // Refer to the esp-idf The component of is equal to stm32 Library function 

3、 ... and 、 Component files reference other components

• At other points c Introduce other points under the file c The file only needs to be in CmakeList Import the corresponding header file under the file, such as
