1 FreeCalypso Luna phone handset UI development platform consists of these 3
2 components:
3
4 * A Caramel-type Calypso motherboard, either iWOW DSK or FC Caramel2
5 * An LCD carrier board, currently using HaoRan HT020K1QC36S LCD module
6 * A 5x5 keyswitch matrix board for the keypad function
7
8 This Luna is our primary official platform for FreeCalypso phone handset UI
9 development. The UI code we got from TI comes in two interesting versions:
10
11 * Big color version: 176x220 pixels, 16-bit color
12 * Small B&W version: originally 84x48 pixels, we are extending it to 96x64 pix
13
14 (Originally there was also a third version, large 176x220 pix B&W, but we find
15 it uninteresting and we've removed it from our supported set. It was really
16 nothing more than a hack to display a minimal-effort derivative of the original
17 small B&W UI on the large D-Sample LCD, so we are not removing anything of any
18 real substance here.)

20 FC Luna hardware is required for anyone who wishes to work on the phone handset
21 UI project in FC Tourmaline: it is the only target platform that can display
22 both versions of our work-in-progress UI firmware. Mot C1xx and other similar
23 phones have small LCDs that can only display the small B&W version of our
24 TI-based UI, and in the Mother's opinion working solely on the smallbw version
25 to the exclusion of the bigcolor version is not acceptable.
