Pixel Format
Each pixel in the RainbowDashboard buffer has a control channel, a red channel, a green channel, and a blue channel. A pixel may have any of the following formats:
00000000 rrrrrrrr gggggggg bbbbbbbb : A solid color.
00000rgb rrrrrrrr gggggggg bbbbbbbb : An animation.
The control channel determines whether each other channel is a fixed color value (0) or an animation slot number (1). See Animation.
1fffffff 00bbbbbb dddd0000 pppppppp : An indexed color.
The control channel determines the field number, with fields 0-63 being clock values and fields 64-127 being user-defined register values. See Fields.
The red channel determines the base and the green channel determines the digit. See Bases.
The blue channel determines which palette is used. The value of the field is divided by (base^digit) and then used as an index into the specified palette. See Palettes.
1fffffff 01bbbbbb ddddr0r1 g0g1b0b1 : A gradient.
The control channel determines the field number, with fields 0-63 being clock values and fields 64-127 being user-defined register values. See Fields.
The red channel determines the base and the upper half of the green channel determines the digit. See Bases.
The lower half of the green channel actually determines the red values of the two endpoints of the gradient. The upper half of the blue channel determines the green values, and the lower half of the blue channel determines the blue values.
The value of the field is divided by (base^digit) and then put on a scale between 0 and base-1, with 0 corresponding to r0g0b0 and base-1 corresponding to r1g1b1.
1fffffff 10bbbbbb ddddr0r1 g0g1b0b1 : A 4x4 character display.
The control channel determines the field number, with fields 0-63 being clock values and fields 64-127 being user-defined register values. See Fields.
The red channel determines the base and the upper half of the green channel determines the digit. See Bases.
The lower half of the green channel actually determines the red values of the background and foreground. The upper half of the blue channel determines the green values, and the lower half of the blue channel determines the blue values.
The value of the field is divided by (base^digit) and then displayed as a 4x4 character with background color r0g0b0 and foreground color r1g1b1. See Fonts.
The same pixel value must be applied to a 4x4 area in the upper left, upper right, lower left, or lower right to get the whole display.
1fffffff 11bbbbbb ddddr0r1 g0g1b0b1 : An 8x8 character display.
The control channel determines the field number, with fields 0-63 being clock values and fields 64-127 being user-defined register values. See Fields.
The red channel determines the base and the upper half of the green channel determines the digit. See Bases.
The lower half of the green channel actually determines the red values of the background and foreground. The upper half of the blue channel determines the green values, and the lower half of the blue channel determines the blue values.
The value of the field is divided by (base^digit) and then displayed as an 8x8 character with background color r0g0b0 and foreground color r1g1b1. See Fonts.
The same pixel value must be applied to the entire 8x8 LED matrix to get the whole display.
