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	9c37471780	ti/kbd: improve debouncing ... Previously, on real hardware (emulator behaved fine), we would routinely get repeat keys unless pressing the button very fast. This commit solves that.	2019-11-09 13:22:01 -05:00
Virgil Dupras	418af5f626	ti/kbd: make Alpha and 2nd toggle ... Previously, when being in A-Lock mode, activating Alpha wouldn't make us go temporarily in digit mode, as is expected.	2019-11-09 13:12:36 -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
