Arduboy-TinyFont

Tiny 4x4 Font for Arduboy which contains the small ASCII Table from 32 to 127.
The sprite for the font uses 192 bytes.
The last character 127 is supposed to bel DEL but i used it as a placeholder (■) for not found characters.

Preview

Usage:

Make an instance of Tinyfont and initialize it with a screenbuffer with corresponding sizes.
Call print() with you c-string and position to draw text to the screen.

Sample:

Tinyfont tinyfont = Tinyfont(arduboy.sBuffer, Arduboy2::width(), Arduboy2::height());
tinyfont.setCursor(0, 0);
tinyfont.print("The quick brown fox jumps\nover the lazy dog.");  

Dependencies:

Subclass of Arduino Print.

Customization:

You can adjust letterSpacing and lineHeight.

Custom characters:

You can add custom characters above 127 (up to index 255) by using the 4x4font.png as base.
Edit the file (or the .psd) in an image editor of your choice. But be sure to always append 8x8 pixels at the end which you can fill as you like. Throw the new .png through a image converter and replace the sprite in TinyfontSprite.c with your new data.

Optimization:

I'm pretty sure this can be optimized since it takes a lot of space.

Arduboy2::print()

Sketch uses 7902 bytes (27%) of program storage space

Tinyfont::print()

Sketch uses 8834 bytes (30%) of program storage space.

Both:

Sketch uses 8918 bytes (30%) of program storage space
