Quick Start Guide for the mono graphics service

This is the quick start guide for the Monochrome Graphics service, with step-by-step instructions on how to configure and use it for a specific use case.

Basic usage of the graphics service

This use case will demonstrate initializing the mono graphics service and then draw a black line on the screen from coordinates X=10, Y=10 to X=20, Y=20.

Usage steps

Example code

Add to, e.g., the main function in the application C-file:

system_init();
gfx_mono_init();
gfx_mono_draw_line(10, 10, 20, 20, GFX_PIXEL_SET);

Workflow

1. Initialize system:

   • system_init(); 

2. Initialize monochrome graphics service

   • gfx_mono_init(); 

   • Note

     This will call the init function for the low level display controller driver and intialize the screen to a cleared background.

3. Draw a line from 10,10 to 20,20:

• gfx_mono_draw_line(10, 10, 20, 20, GFX_PIXEL_SET); 

• Note

  This uses GFX_PIXEL_SET to set the display pixels on the line; other options can be found in gfx_mono_color.
