DIY: adding s/pdif LED display to an existing DAC
for more info on this project, see: www.amb.org/forum/lcduino-code-that-displays-spdif-sample...
user interface detail: the left group of leds show the digital audio frequency (sample rate). only 1 will be on at a time (or none) and I only had 3 colors to work with; but from a distance you can tell which of the leds is on by the color and whether its toward the left side or the right side. no 'digits' display is really needed, and in fact, would be less readable at a distance than this scheme.
the right 3 leds will show which one of the rear inputs is selected; only 1 of the leds will be on just as only 1 of the inputs could be selected at a time.
very minimal drilling (or drilling skills, lol) needed for this user-interface style.
I plan to label the leds, but after a while, you get to know what they mean and labels only clutter up the front.
