Virgil Dupras	c4658591bd	ti/lcd: allow for fonts smaller than 5 pixels ... That's a lot of code for such a small change, but there's a big difference between 5 pixels and 4 pixels: 4 pixels requires compositing.	2019-11-09 22:55:15 -05:00

Virgil Dupras	ca84b5dac8	recipes/ti84: first step ... This was mostly lifted from my "tihello" example, but it required significant adjustments. This commit also introduces a font management system. A lot of fonts are available online, but sources aren't always clear so to avoid copyright landmines, I re-created my first 5x7 font from scratch. As it is now, this resulting ROM gets "Collapse OS>" to be displayed on the LCD screen. Much work still left to do. ref #41	2019-11-07 11:52:29 -05:00
