How to use it?

Hello, thanks for sharing this.
Is there any instruction on how to use it?

There is no further documentation fort his library. There's no abstraction layer on top (like we are used from environments like Arduino), so that you have to get started by changing the code (mainly #define in the .h files) to match your project hardware.

The first step is to edit dogm-graphic.h and add all the necessary configuration for your board (e.g. the pin-out and choice of display and uC).

In your main program, you have to call lcd_init() to initialize the display before using it.
Then you can use e.g. the lcd_put_* functions (listed in font.h) to write text to the display.
