FTM280C34D display using ILI9325 display controller

This is hardware specific configuration that configures the graphical service for use with the ILI9325 display controller and the ET024006DHU 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.

gfx_color_t gfx_ili9325_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

r	8-bit red value.
g	8-bit green value.
b	8-bit blue value.

Returns

Color value in display native format.

References GFX_COLOR.

void gfx_ili9325_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

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.

void gfx_ili9325_draw_pixel	(	gfx_coord_t	x,
		gfx_coord_t	y,
		gfx_color_t	color
	)

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

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.

References gfx_max_x, gfx_max_y, gfx_min_x, gfx_min_y, gfx_set_limits(), and ili9325_write_gram().

gfx_color_t gfx_ili9325_get_pixel	(	gfx_coord_t	x,
		gfx_coord_t	y
	)

Get the color of a pixel on the display.

Parameters

x	X coordinate of the pixel to be sampled.
y	Y 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.
