This is hardware specific configuration that configures the graphical service for use with the ILI9488 display controller and the 90-00028-A0 display.

All the drawing functionality in this configuration is provided by the Generic Implementation of Graphics Primitives driver. This configuration includes information about the panel size, data type used for coordinates and color and functionality to convert RGB color to the color format native to the display.

Generate native color value from R/G/B values.

Converts 8-bit R/G/B values to a color value native to the display.

The macro GFX_COLOR does the same, only allows the preprocessor to handle the calculations.

Parameters

r	8-bit red value.

Draw a single pixel on the screen.

This function draws a single pixel on screen only setting top limit which makes it more suitable for line drawing. If outside the clipping region, nothing is drawn.

Parameters

x	X coordinate of the pixel to be drawn.
y	Y coordinate of the pixel to be drawn.
color	Color value of the pixel in display native format.
