| Well Fed Games:
Never thought ICB/ZP were that interesting, and I know now the theme had something to do with that. This looks great! Can't wait to hear the audio! |

imho, art and audio are great, and i'm glad we came up with a solution that allows for no loss in quality of the audio. for those interested in the guts: * Main logic running on a Freescale KL25Z, using mbed platform * Audio being handled by the cheapest solution available - a small cheap external board (a raspberry-pi) * Freescale and rpi connected via usb, and use a usb-serial setup to chat to each other * Display is a set of 16-segment displays, a row of 5, over a row of similar but with 2nd removed (so, 1 unit, blank, 3 units) - as per artwork above, top-right. These are multiplexed - cycled in columns; one column is powered at a time, the KL25z sets the segments to display and cycles which column to be powered at a high frequency. A series of 4 shift registers hold the state of the segments. * 10 RGB LED's hide behind each hole that can be used for scoring. The KL25z simulates PWM by cycling the on-off state as needed. These are multiplexed as well, to keep pin count down. * 10 switches - one for each score hole, tied to a 10/4 priority encoder to reduce pin count * Limit switches used to control the extent to which the bar can move - four switches tied to interrups for immediate response * Dip switches to control a few configurable items. * More config available via a config file stored on the SD card in the r-pi * High scores maintained on SD card * Servo motors for the bar tied to PWM units on the KL25z * "Tilt" sensed by KL25z built in accelerometer * High-score input will be like robotron. Left stick selects letter, right stick accepts * etc This thing requires a lot of I/O pins and is the most complicated microcontroller thing I've done to date to date. |
