Display text and bitmaps on strip led panels.
Fonts range between 4 cols x 6 lines and 8 cols x 13 lines. Panels must have at least 5 lines - to display 4x6 font in big caps only.
Strip led serpentine wrap on the panel is supported by columns or by lines, panel led origin can be at top left / top right / bottom left / bottom right, and it is possible to combine heterogeneous panels.
This programs uses the QDBMP library for bitmap management. The fonts used are the ISO8859 FixedMedium from the /usr/share/fonts/X11/misc/ folder on Linux.
Text and bitmap display APIs on StripDisplay.h
To save memory space, fonts are only included on demand using preprocessing directives, for instance #define FONT_5x8_FIXED_MEDIUM before the #include <StripDisplay.h> line.
See the AllFonts.ino example for all the available fonts.
By default, all 224 printable ISO8859-1 (latin) characters are available.
To reduce memory footprint, #define FONT_CHARSET_MEDIUM before the #include <StripDisplay.h> line to use only the 32..127 character range.
The #define FONT_CHARSET_SMALL directive uses only the 32..95 character range. In that configuration, lowercase characters are automatically remapped to uppercase.
Examples displaying text, sprites, and adressing pixels on 8 lines / 32 columns strip LED panels.
The Hello.ino example displays the string "Hello" in a 6x9 fixed font, on a 32x8 strip led panel.
The Stacking.ino example vertically stacks two 32x8 strip led panels to make a 32x16 bitmap. In shows the bitmap-level pixel addressing by x,y coordinates API, low level text rendering, and high level text display API with scrolling.
The AllFonts.ino example shows all available fonts, from 4x6 to 8x13 bold, on two stacked 32x8 strip led panels.
The SpaceInvaders.ino example shows how to render sprites from xbm bitmaps.
The MessageBoard.ino example continuously scrolls a text message at fixed speed, while reading text updates from the serial port.
