# Basic information

This routine is verified using the corresponding module with the PICO. 

You can see the corresponding test routine in the examples\ of the project.

## Basic use

You need to execute:

If the directory already exists, you can go directly. If there is no build directory, execute

```sh

mkdir build

```

Enter the build directory and type in the terminal:

```sh

cd build

export PICO_SDK_PATH="/opt/pico_sdk"

```

Where `/opt/pico_sdk` is your installed SDK directory

Execute cmake, automatically generate Makefile file, enter in the terminal:

```sh

cmake -GNinja ..

```

Execute make to generate an executable file, and enter in the terminal:

```sh

ninja

```

Copy the compiled uf2 file to pico

## Directory structure (selection)

If you use our products frequently, we will be very familiar with our program directory structure. We have a copy of the specific function.

The API manual for the function, you can download it on our WIKI or request it as an after-sales customer service. Here is a brief introduction:

Config\: This directory is a hardware interface layer file. You can see many definitions in DEV_Config.c(.h), including:

   type of data;

    GPIO;

    Read and write GPIO;

    Delay: Note: This delay function does not use an oscilloscope to measure specific values.

    Module Init and exit processing:

        void DEV_Module_Init(void);

        void DEV_Module_Exit(void);

**\lib\GUI\:** This directory is some basic image processing functions, in GUI_Paint.c(.h):

    Common image processing: creating graphics, flipping graphics, mirroring graphics, setting pixels, clearing screens, etc.

    Common drawing processing: drawing points, lines, boxes, circles, Chinese characters, English characters, numbers, etc.;

    Common time display: Provide a common display time function;

    Commonly used display pictures: provide a function to display bitmaps;

**\lib\Fonts\:** for some commonly used fonts:

    Chinese:

        font12CN: 16*21

        font24CN: 32*41

**\lib\LCD\:** This directory is the LCD driver function;

**examples\:** This directory is the test program of LCD, you can see the specific usage method in it;
