How to Create CMSIS-Pack

STEP 1 Update 'lv_conf_cmsis.h'

Copy the lv_conf_template.h to 'cmsis-pack' directory
Set the macro protector to '1'

...
/* clang-format off */
#if 1 /*Set it to "1" to enable content*/
...

remove the misleading guide above this code segment.

/*
 * Copy this file as `lv_conf.h`
 * 1. simply next to the `lvgl` folder
 * 2. or any other places and
 *    - define `LV_CONF_INCLUDE_SIMPLE`
 *    - add the path as include path
 */

Add including for 'RTE_Components.h'

#ifndef LV_CONF_H
#define LV_CONF_H

#include <stdint.h>
#include "RTE_Components.h"
...

Remove macro definitions for
- LV_USE_GPU_STM32_DMA2D
- LV_USE_GPU_NXP_PXP
- LV_USE_GPU_NXP_VG_LITE
- LV_USE_GPU_SWM341_DMA2D
- LV_USE_GPU_ARM2D
- LV_USE_IME_PINYIN
- LV_USE_PNG
- LV_USE_BMP
- LV_USE_SJPG
- LV_USE_GIF
- LV_USE_QRCODE
- LV_USE_FREETYPE
- LV_USE_TINY_TTF
- LV_USE_RLOTTIE
- LV_USE_FFMPEG
- LV_USE_SNAPSHOT
- LV_USE_MONKEY
- LV_USE_GRIDNAV
- LV_USE_FRAGMENT
- LV_USE_IMGFONT
- LV_USE_MSG
- LV_USE_IME_PINYIN
Update macro LV_ATTRIBUTE_MEM_ALIGN and LV_ATTRIBUTE_MEM_ALIGN_SIZE to force a WORD alignment.

#define LV_ATTRIBUTE_MEM_ALIGN_SIZE     4
#define LV_ATTRIBUTE_MEM_ALIGN          __attribute__((aligned(4)))

Update macro LV_MEM_SIZE to (64*1024U).

Update macro LV_FONT_MONTSERRAT_12 to 1.

Update Theme related macros:

#ifdef RTE_GRAPHICS_LVGL_USE_EXTRA_THEMES
    /*A simple, impressive and very complete theme*/
    #define LV_USE_THEME_DEFAULT 1
    #if LV_USE_THEME_DEFAULT

        /*0: Light mode; 1: Dark mode*/
        #define LV_THEME_DEFAULT_DARK 0

        /*1: Enable grow on press*/
        #define LV_THEME_DEFAULT_GROW 1

        /*Default transition time in [ms]*/
        #define LV_THEME_DEFAULT_TRANSITION_TIME 80
    #endif /*LV_USE_THEME_DEFAULT*/

    /*A very simple theme that is a good starting point for a custom theme*/
    #define LV_USE_THEME_BASIC 1

    /*A theme designed for monochrome displays*/
    #define LV_USE_THEME_MONO 1
#else
    #define LV_USE_THEME_DEFAULT    0
    #define LV_USE_THEME_BASIC      0
    #define LV_USE_THEME_MONO       0
#endif

Update LV_TICK_CUSTOM related macros:

/*Use a custom tick source that tells the elapsed time in milliseconds.
 *It removes the need to manually update the tick with `lv_tick_inc()`)*/
#ifdef __PERF_COUNTER__
    #define LV_TICK_CUSTOM 1
    #if LV_TICK_CUSTOM
        extern uint32_t SystemCoreClock;
        #define LV_TICK_CUSTOM_INCLUDE          "perf_counter.h"
        #define LV_TICK_CUSTOM_SYS_TIME_EXPR    get_system_ms()
    #endif   /*LV_TICK_CUSTOM*/
#else
    #define LV_TICK_CUSTOM 0
    #if LV_TICK_CUSTOM
        #define LV_TICK_CUSTOM_INCLUDE "Arduino.h"         /*Header for the system time function*/
        #define LV_TICK_CUSTOM_SYS_TIME_EXPR (millis())    /*Expression evaluating to current system time in ms*/
    /*If using lvgl as ESP32 component*/
    // #define LV_TICK_CUSTOM_INCLUDE "esp_timer.h"
    // #define LV_TICK_CUSTOM_SYS_TIME_EXPR ((esp_timer_get_time() / 1000LL))
    #endif   /*LV_TICK_CUSTOM*/
#endif       /*__PERF_COUNTER__*/

Remove all content in DEMO USAGE section but keep the following:

/*Show some widget. It might be required to increase `LV_MEM_SIZE` */
#if LV_USE_DEMO_WIDGETS
	#define LV_DEMO_WIDGETS_SLIDESHOW 0
#endif

/*Benchmark your system*/
#if LV_USE_DEMO_BENCHMARK
/*Use RGB565A8 images with 16 bit color depth instead of ARGB8565*/
	#define LV_DEMO_BENCHMARK_RGB565A8 1
#endif

Thoroughly remove the 3rd party libraries section.
rename 'lv_conf_template.h' to 'lv_conf_cmsis.h'.

STEP 2 Check, Update and Run the 'gen_pack.sh'

if [ `uname -s` = "Linux" ]
  then
  CMSIS_PACK_PATH="/home/$USER/.arm/Packs/ARM/CMSIS/5.7.0/"
  PATH_TO_ADD="$CMSIS_PACK_PATH/CMSIS/Utilities/Linux64/"
else
  CMSIS_PACK_PATH="/C/Users/gabriel/AppData/Local/Arm/Packs/ARM/CMSIS/5.7.0"
  PATH_TO_ADD="/C/Program Files (x86)/7-Zip/:$CMSIS_PACK_PATH/CMSIS/Utilities/Win32/:/C/xmllint/"
fi
[[ ":$PATH:" != *":$PATH_TO_ADD}:"* ]] && PATH="${PATH}:${PATH_TO_ADD}"
echo $PATH_TO_ADD appended to PATH
echo " "

A. For Windows users

Update the 'CMSIS_PACK_PATH' accordingly (Usually just replace the name gabriel with your own windows account name is sufficient.).

Update the 'PATH_TO_ADD' to point to the installation folders of 7Zip and xmllint.

Launch the git-bash and go to the cmsis-pack folder.

enter the following command:

./gen_pack.sh

B. For Linux Users

Update 'PATH_TO_ADD' if necessary.

go to the cmsis-pack folder.
