- ubb-vga.h (ccube_init, ccube_map), ccube.c: color mapper based on proximity in color cube - grabfb.c (pattern, grabfb), ppmimg.c (pattern, convert): use the color cube mapper instead of inferios threshold-based mapping - ubb-vga2.c (session): initialize the color cube - ubb-vga.h (thres), grabfb.c (thres), ubb-vga2.c (usage, main): removed the threshold along with the option (-l) to set it - Makefile (OBJS): added ccube.o |

Ben Blinkenlights ================= This project is a proof of concept implementation of Rikard Lindstrom's idea of using the Ben's 8:10 card slot as a general extension interface also for devices that don't speak MMC or SD/SDIO. The application is a simple LED circuit, as suggested by David Samblas. The 8:10 card slot gives access to six GPIOs, a 3.3 V supply that can be switched on and off by software, and ground. We use a simple form of multiplexing to drive ten LEDs with this interface. Note that one should only light one LED at a time. If multiple LEDs are lit, they will share the current though the common resistor, and will thus be less bright than a single LED.
