90_00028_A0 display using ILI9488 display controller

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.

#define gfx_draw_circle (   x,
  y,
  radius,
  color,
  octant_mask 
)    gfx_generic_draw_circle(x, y, radius, color, octant_mask)

Draw an outline of a circle or arc.

ILI9488 display driver uses generic gfx implementation for this function.

The radius is the distance from the center to the circumference, which means that the total width or height of a circle will be (radius*2+1).

The octant_mask parameter is a bitmask that decides which octants of the circle to draw. Use the GFX_OCTANTn, GFX_QUADRANTn, GFX_xHALF and GFX_WHOLE constants and OR them together if required. Radius equal to zero gives a single pixel.

Parameters
xX coordinate of center.
yY coordinate of center.
radiusCircle radius in pixels.
colorCircle color in display native format.
octant_maskBitmask indicating which octants to draw.

void gfx_generic_draw_filled_circle(gfx_coord_t x, gfx_coord_t y, gfx_coord_t radius, gfx_color_t color, uint8_t quadrant_mask)
Definition: gfx_generic.c:296

Draw a filled circle or sector.

ILI9488 display driver uses generic gfx implementation for this function.

The radius is the distance from the center to the circumference, which means that the total width or height of a circle will be (radius*2+1).

The quadrant_mask parameter is a bitmask that decides which quadrants of the circle to draw. Use the GFX_QUADRANTn, GFX_xHALF and GFX_WHOLE constants and OR them together if required. Radius equal to zero gives a single pixel.

Note
This function only supports quadrants while gfx_draw_circle() supports octants. This is to improve performance on drawing filled circles.
Parameters
xX coordinate of center.
yY coordinate of center.
radiusCircle radius in pixels.
colorCircle color in display native format.
quadrant_maskBitmask indicating which quadrants to draw.

Definition: gfx_generic.c:358

Read a rectangular block of pixels from the screen into data memory.

ILI9488 display driver uses generic gfx implementation for this function.

If the area to read is outside the clipping region, those pixels will not be read, and the corresponding data memory will be left untouched. Note that this function fails if width or height is negative or the pixel rectangle is outside the pixmap buffer extents. Clipping is only performed on the screen, not inside the pixmap buffer itself. Note that there is no checking if the pixel rectangle exceeds the bottom of the pixmap buffer.

Parameters
pixmapPointer to pixel buffer in data memory.
map_widthWidth of the pixel buffer.
map_xX coordinate inside pixel buffer.
map_yY coordinate inside pixel buffer.
xX coordinate on screen.
yY coordinate on screen.
widthWidth of pixel rectangle to copy.
