SDT028ATFT display using ILI9341 display controller

This is hardware specific configuration that configures the graphical service for use with the ILI9341 display controller and the SDT028ATFT 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.

Data type for color values native to the display.

Data type representing a coordinate on the screen.

gfx_color_t gfx_ili9341_color ( uint8_t  r,
uint8_t  g,
uint8_t  b 
)

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
r8-bit red value.
g8-bit green value.
b8-bit blue value.
Returns
Color value in display native format.

References GFX_COLOR.

void gfx_ili9341_draw_line_pixel ( gfx_coord_t  x,
gfx_coord_t  y,
gfx_color_t  color 
)

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
xX coordinate of the pixel to be drawn.
yY coordinate of the pixel to be drawn.
colorColor value of the pixel in display native format.

void gfx_ili9341_draw_pixel ( gfx_coord_t  x,
gfx_coord_t  y,

)

Draw a single pixel on the screen.

Draw a single pixel on screen setting top and bottom limits. If outside the clipping region, nothing is drawn.

Parameters
xX coordinate of the pixel to be drawn.
yY coordinate of the pixel to be drawn.
colorColor value of the pixel in display native format.

gfx_color_t gfx_ili9341_get_pixel ( gfx_coord_t  x,
gfx_coord_t  y 
)

Get the color of a pixel on the display.

Parameters
xX coordinate of the pixel to be sampled.
yY coordinate of the pixel to be sampled.
Returns
Color value of the pixel at (x, y) in display native format, or GFX_COLOR_INVALID if outside the clipping region.
