## How to build GuiLite libary for any MCU?
### Prerequisite: Install Keil uvsion 5.6 or above.
### Build
- Open `GuiLite.uvprojx` with Keil uvsion.
- Implement function(e.g, thread_sleep) in `core\src\adapter\api_unknow.cpp` to meet your need.
- Choose your Device type(Default: STM32F103ZE) from option for target.
- Build GuiLite.
- Output here: /GuiLite/Objects/GuiLite.lib

## How to port?
Here are 2 options for porting. 

### Option 1: 1 Header & 1 Source
1. Execute `1h-1cpp.sh` to merge the whole source code into: 1 header(GuiLite.h) & 1 source(GuiLite.cpp)
2. Move GuiLite.h/GuiLite.cpp to your project
3. Rebuild your project

### Option 2: Headers & 1 Library
- Headers: core_include, widgets_include
- Library: The GuiLite library
1. Move core_include/widgets_include to your project
2. Build GuiLite library by above building process
3. Link GuiLite library to your project
4. Rebuild your project

We recommend option 1, because of:
- Easy to port - no need to buid library
- Easy to move - just 2 files
- Easy to manage header files - just 1 header file
- Easy to debug - no library binary

On the other hand, for option 2: you should build GuiLite library, and move all headers files & library to your project.
