Commands

RainbowDashboard has 48 commands, listed below in both short and long formats.

All commands that set pixels operate on a temporary buffer to eliminate flicker. SHOW_IMAGE, SHOW_CHARACTER, SHOW_COLOR, and SHOW_PIXEL will immediately switch buffers, so their effects will be immediately visible. Other commands, however, will not switch buffers, so their effects will not be visible until you send the SWAP_BUFFER command.

RainbowDashboard includes a complete Windows ANSI (CP1252) character set (technically Kreative SuperLatin, a superset) in both 4x4 and 8x8 font sizes, displayed using the SHOW_CHARACTER, DRAW_CHAR_8x8, and DRAW_CHAR_4x4 commands. See Fonts.

It also includes eight built-in images displayed using the SHOW_IMAGE and DRAW_IMAGE commands, the first five of which are identical to the built-in images provided by the standard firmware. See Pictures. Image number 6 is particularly useful when determining desired gamma levels to be set with the SET_GAMMA command.
