Life got a bit busy recently so I haven't been able to update as frequently as I would like, but the docking station is almost complete now after several bugs were squashed with the serial input routine handler loop! I'd say I'm about 60% of the way there.
A simple button toggles all of the metadata sent over to the end user. I have also integrated sleep mode now so that the display will sleep with inactivity after 1 min. The user can wake the dock by pressing the button or by doing any other command, like exiting a game or re-entering a different game, for example. This prevents OLED burn in (yeah, I know, pretty unlikely... but it never hurt to be cautious).
The remaining features include showing some play statistics such as most games played by times and duration, game description via hardware scrolling and other metadata + a small video of each game. Also shutting the dock down when the system is powered off should be relatively simple, too so that it doesn't hang when power is killed from the regulators.
Next post, hopefully in the cutting edge!
