Usage Instructions

ESP32-S3-Touch-AMOLED-1.64 currently provides two development tools and frameworks, Arduino IDE and ESP-IDF, providing flexible development options, you can choose the right development tool according to your project needs and personal habits.

Development Tools

Arduino IDE

Arduino IDE is an open source electronic prototyping platform, convenient and flexible, easy to get started. After a simple learning, you can start to develop quickly. At the same time, Arduino has a large global user community, providing an abundance of open source code, project examples and tutorials, as well as rich library resources, encapsulating complex functions, allowing developers to quickly implement various functions.

ESP-IDF

ESP-IDF, or full name Espressif IDE, is a professional development framework introduced by Espressif Technology for the ESP series chips. It is developed using the C language, including a compiler, debugger, and flashing tool, etc., and can be developed via the command lines or through an integrated development environment (such as Visual Studio Code with the Espressif IDF plugin). The plugin offers features such as code navigation, project management, and debugging, etc.

Each of these two development approaches has its own advantages, and developers can choose according to their needs and skill levels. Arduino are suitable for beginners and non-professionals because they are easy to learn and quick to get started. ESP-IDF is a better choice for developers with a professional background or high performance requirements, as it provides more advanced development tools and greater control capabilities for the development of complex projects.

Components Preparation

Code analysis

For LVGL, lvgl_conf.h is its configuration file. Below, some commonly used settings are explained, and some LVGL demos and file systems can also be configured in the conf file

/*Color depth: 1 (1 byte per pixel), 8 (RGB332), 16 (RGB565), 32 (ARGB8888)*/
#define LV_COLOR_DEPTH 16//Color depth, a macro definition that must be concerned with porting LVGL


#define LV_MEM_CUSTOM 0
#if LV_MEM_CUSTOM == 0
    /*Size of the memory available for `lv_mem_alloc()` in bytes (>= 2kB)*/
    #define LV_MEM_SIZE (48U * 1024U)          /*[bytes]*/

    /*Set an address for the memory pool instead of allocating it as a normal array. Can be in external SRAM too.*/
    #define LV_MEM_ADR 0     /*0: unused*/
    /*Instead of an address give a memory allocator that will be called to get a memory pool for LVGL. E.g. my_malloc*/
    #if LV_MEM_ADR == 0
        #undef LV_MEM_POOL_INCLUDE
        #undef LV_MEM_POOL_ALLOC
    #endif

#else       /*LV_MEM_CUSTOM*/
    #define LV_MEM_CUSTOM_INCLUDE <stdlib.h>   /*Header for the dynamic memory function*/
    #define LV_MEM_CUSTOM_ALLOC   malloc
    #define LV_MEM_CUSTOM_FREE    free
    #define LV_MEM_CUSTOM_REALLOC realloc
#endif     /*LV_MEM_CUSTOM*/
//The above section is mainly for LVGL memory allocation, 
//which defaults to lv_mem_alloc() versus lv_mem_free().

Code modification

The display chip itself does not support hardware rotation. If rotation is needed, it can be achieved through software. You can find the macro definition #define EXAMPLE_Rotate_90 in lcd_bsp.c file and uncomment this macro definition. Software rotation performance is not as good as hardware rotation.

//#define EXAMPLE_Rotate_90

ESP-IDF Project Details

Component: The components in ESP-IDF are the basic modules for building applications, each component is usually a relatively independent code base or library, which can implement specific functions or services, and can be reused by applications or other components, similar to the definition of libraries in Python development.
- Component reference: The import of libraries in the Python development environment only requires to "import library name or path", while ESP-IDF is based on the C language, and the importing of libraries is configured and defined through CMakeLists.txt.
- The purpose of CmakeLists.txt: When compiling ESP-IDF, the build tool CMake first reads the content of the top-level CMakeLists.txt in the project directory to read the build rules and identify the content to be compiled. When the required components and demos are imported into the CMakeLists.txt, the compilation tool CMake will import each content that needs to be compiled according to the index. The compilation process is as follows:
