How to Create CMSIS-Pack

STEP 1 Update 'lv_conf_cmsis.h'

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

2. 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
 */

3. Add including for 'RTE_Components.h'

#ifndef LV_CONF_H
#define LV_CONF_H

#include "RTE_Components.h"
...

4. Remove macro definitions for

   • LV_USE_DEMO_WIDGETS

   • LV_USE_DEMO_BENCHMARK

   • LV_USE_IME_PINYIN

   • LV_USE_OS

   • LV_USE_FILE_EXPLORER

   • LV_USE_DEMO_WIDGETS

   • LV_USE_DEMO_KEYPAD_AND_ENCODER

   • LV_USE_DEMO_BENCHMARK

   • LV_USE_DEMO_RENDER

   • LV_USE_DEMO_STRESS

   • LV_USE_DEMO_MUSIC

   • LV_USE_DEMO_FLEX_LAYOUT

   • LV_USE_DEMO_MULTILANG

   • LV_USE_DEMO_TRANSFORM

   • LV_USE_DEMO_SCROLL

   • LV_USE_DEMO_VECTOR_GRAPHIC

   • LV_USE_DRAW_VGLITE

   • LV_USE_DRAW_VG_LITE

   • LV_USE_DRAW_PXP

   • LV_USE_DRAW_SDL

   • LV_USE_DRAW_ARM2D

   • LV_USE_SNAPSHOT

   • LV_USE_MONKEY

   • LV_USE_GRIDNAV

   • LV_USE_FRAGMENT

   • LV_USE_IMGFONT

   • LV_USE_LINUX_DRM

   • LV_USE_TFT_ESPI

   • LV_USE_ST7735

   • LV_USE_ST7789

   • LV_USE_ST7796

   • LV_USE_ILI9341

5. Update LV_LOG_PRINTF to 1 and LV_LOG_LEVEL to LV_LOG_LEVEL_USER

6. Set LV_FONT_MONTSERRAT_12, LV_FONT_MONTSERRAT_24 and LV_FONT_MONTSERRAT_16 to 1 (So Widgets and Benchmark can be compiled correctly, this is for improving the out of box experience.)

7. Update macro LV_ATTRIBUTE_MEM_ALIGN and LV_ATTRIBUTE_MEM_ALIGN_SIZE to force a WORD alignment.

#define LV_ATTRIBUTE_MEM_ALIGN_SIZE     1
#define LV_DRAW_BUF_STRIDE_ALIGN		4
#define LV_ATTRIBUTE_MEM_ALIGN          __attribute__((aligned(4)))

Make sure LV_MEM_SIZE is no less than (96*1024U).

8. Remove following macro definitions in the 3rd party libraries section:

   • #define LV_USE_FS_STDIO 0
   • #define LV_USE_FS_POSIX 0
   • #define LV_USE_FS_WIN32 0
   • #define LV_USE_FS_FATFS 0
   • #define LV_USE_FS_MEMFS 0
   • #define LV_USE_LODEPNG 0
   • #define LV_USE_LIBPNG 0
   • #define LV_USE_BMP 0
   • #define LV_USE_RLE 0
   • #define LV_USE_TJPGD 0
   • #define LV_USE_LIBJPEG_TURBO 0
   • #define LV_USE_GIF 0
   • #define LV_USE_BARCODE 0
   • #define LV_USE_QRCODE 0
   • #define LV_USE_FREETYPE 0
   • #define LV_USE_TINY_TTF 0
   • #define LV_USE_RLOTTIE 0
   • #define LV_USE_FFMPEG 0

9. update the definition of following macros: LV_USE_VECTOR_GRAPHIC, LV_USE_THORVE_INTERNAL and LV_USE_THORVE_EXTERNAL as

   /*Enable Vector Graphic APIs*/
   #ifndef LV_USE_VECTOR_GRAPHIC
   #   define LV_USE_VECTOR_GRAPHIC  0
   
   /* Enable ThorVG (vector graphics library) from the src/libs folder */
   #   define LV_USE_THORVG_INTERNAL 0
   
   /* Enable ThorVG by assuming that its installed and linked to the project */
   #   define LV_USE_THORVG_EXTERNAL 0
   #endif
   

10. update the definition of following macros: LV_USE_LZ4, LV_USE_LZ4_INTERNAL and LV_USE_LZ4_EXTERNAL as

    /*Enable LZ4 compress/decompress lib*/
    #ifndef LV_USE_LZ4
    #   define LV_USE_LZ4  0
    
    /*Use lvgl built-in LZ4 lib*/
    #   define LV_USE_LZ4_INTERNAL  0
    
    /*Use external LZ4 library*/
    #   define LV_USE_LZ4_EXTERNAL  0
    #endif
    

11. Add the following code to HAL SETTINGS:

/*customize tick-get */
#if defined(__PERF_COUNTER__) && __PERF_COUNTER__
    #define LV_GLOBAL_INIT(__GLOBAL_PTR)                                    \
            do {                                                            \
                lv_global_init((lv_global_t *)(__GLOBAL_PTR));              \
                extern uint32_t perfc_tick_get(void);                       \
                (__GLOBAL_PTR)->tick_state.tick_get_cb = perfc_tick_get;    \
            } while(0)
#endif

12. Replace the macro definition:

#define  LV_USE_DRAW_SW_ASM     LV_DRAW_SW_ASM_NONE

with:

    #if !defined(LV_USE_DRAW_SW_ASM) && defined(RTE_Acceleration_Arm_2D)
        /*turn-on helium acceleration when Arm-2D and the Helium-powered device are detected */
        #if defined(__ARM_FEATURE_MVE) && __ARM_FEATURE_MVE
            #define LV_USE_DRAW_SW_ASM  LV_DRAW_SW_ASM_HELIUM
            #define LV_USE_DRAW_ARM2D   1
        #endif
    #endif

    #ifndef LV_USE_DRAW_SW_ASM
        #define  LV_USE_DRAW_SW_ASM     LV_DRAW_SW_ASM_NONE
    #endif

13. Update macro LV_PROFILER_INCLUDE:

#define LV_PROFILER_INCLUDE "src/misc/lv_profiler_builtin.h"

14. 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/$USER/AppData/Local/Arm/Packs/ARM/CMSIS/5.7.0"
  PATH_TO_ADD="/C/Program Files (x86)/7-Zip/:$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.

enter the following command:

./gen_pack.sh
