# 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 <stdint.h>
|
|
#include "RTE_Components.h"
|
|
...
|
|
```
|
|
|
|
4. Remove macro definitions for
|
|
- LV_USE_GPU_STM32_DMA2D
|
|
- LV_USE_GPU_NXP_PXP
|
|
- LV_USE_GPU_NXP_VG_LITE
|
|
5. Update macro LV_ATTRIBUTE_MEM_ALIGN to force a WORD alignment.
|
|
```c
|
|
#define LV_ATTRIBUTE_MEM_ALIGN __attribute__((aligned(4)))
|
|
```
|
|
6. Update Theme related macros:
|
|
|
|
```c
|
|
#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
|
|
```
|
|
7. Update `LV_TICK_CUSTOM` related macros:
|
|
```c
|
|
/*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"
|
|
|
|
#if __PER_COUNTER_VER__ < 10902ul
|
|
#define LV_TICK_CUSTOM_SYS_TIME_EXPR ((uint32_t)get_system_ticks() / (SystemCoreClock / 1000ul))
|
|
#else
|
|
#define LV_TICK_CUSTOM_SYS_TIME_EXPR get_system_ms()
|
|
#endif
|
|
#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*/
|
|
#endif /*LV_TICK_CUSTOM*/
|
|
#endif /*__PERF_COUNTER__*/
|
|
```
|
|
9. Thoroughly remove the `DEMO USAGE` section.
|
|
10. Thoroughly remove the '3rd party libraries' section.
|
|
10. 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" ]
|
|
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:
|
|
|
|
```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
|
|
```
