Dunno... it's been there since 3.3.0, whch was Dec. 15, 2008.
I have been running version 3.1.1 in my juke since I put it together and have been totally happy with it.
Guess I just missed the update when the DisplayOutputFile was incorporated.
Just glad to know now and maybe I'll get back to working on that part of it.
I tested it with LCD Smartie, so if you're using that you should be good to go.
Cool..... now I just have to dig back through some of the readings abut the LCD Smartie and such to see how I can work that into an LED display versus and LCD display and all that jive. (I know I read something about it one time at least) The microcontroller principals seem about the same, just driving of the LED segments might have to be taken care of differently, etc. I dunno, been awhile since I looked into it.
Either way..... ought to be fun to play with.
