SWIM color definitions

Detailed Description

The Simple Windows Interface manager (SWIM) supports 8-bit RGB323, 12-bit RGB 444 (in a 16-bit field), 15-bit RGB555, 16-bit RGB565, and 24-bit RGB888 (in a 32-bit field) color.

SWIM is configured for the color type at build-time based on the the COLORS_DEF definitions. Select one of the following values to configure SWIM. 8-bit RGB323 : COLORS_DEF = 8 12-bit RGB323: COLORS_DEF = 12 15-bit RGB323: COLORS_DEF = 15 16-bit RGB323: COLORS_DEF = 16 24-bit RGB323: COLORS_DEF = 24

Typedef Documentation

Function Documentation

void lpc_colors_set_palette

(

uint16_t *

palette_table

)

Generate a palette table (only in 8-bit mode)

Parameters

palette_table

: Pointer to palette table (256 entries)

Returns

Nothing

Note

Depending on the target LCD color mapping (either 555 or 565), a palette table will be generated to convert colors stored in 233 format to either 555 or 565 format through a lookup table. If compiled in 16-bit color mode, this will be a NULL function. Select the appropriate define in this function for 555 or 565 color mode displays when using an 256 color frame buffer.
