+# 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'
+
+```c
+...
+/* clang-format off */
+#if 1 /*Set it to "1" to enable content*/
+...
+```
+
+remove the misleading guide above this code segment.
+
+```c
+/*
+ * 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**'
+
+```c
+#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_PXP
+   - LV_USE_DRAW_SDL
+   - LV_USE_DRAW_ARM2D_SYNC
+   - 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
+   - LV_USE_RENESAS_GLCDC   
+   
+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.
+```c
+#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 `(128*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_LITTLEFS 0
+    - #define LV_USE_FS_ARDUINO_ESP_LITTLEFS 0
+    - #define LV_USE_FS_ARDUINO_SD 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 
+
+    ```c
+    /*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 
+
+    ```c
+    /*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`:
+
+```c
+/*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:
+
+```c
+#define  LV_USE_DRAW_SW_ASM     LV_DRAW_SW_ASM_NONE
+```
+
+with:
+
+```c
+    #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_SYNC   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`:
+
+```c
+#define LV_PROFILER_INCLUDE "src/misc/lv_profiler_builtin.h"
+```
+
+
+
+14. Add the following macro definition to **COLOR SETTINGS** section:
+
+```c
+#define LV_COLOR_16_SWAP 0
+```
+
+
+
+14. rename '**lv_conf_template.h**' to '**lv_conf_cmsis.h**'.
+
+
+
+## STEP 2 Check, Update and Run the 'gen_pack.sh'
+
+```sh
+if [ `uname -s` = "Linux" ]

+  PATH_TO_ADD="$CMSIS_PACK_PATH/CMSIS/Utilities/Linux64/"

+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:
+
+```sh
+./gen_pack.sh
+```
+
+
+
+### B. For Linux Users
+
+Update '**PATH_TO_ADD**' if necessary.
+
+go to the **cmsis-pack** folder.
+
+enter the following command:
+
+```sh
+./gen_pack.sh
+```
