Hi,
I have a little project where I want to build my own mp3 based boom blaster. Previously I had the approach of using a PIC/AVR + MP3 decoder-chip but I would like to use some existing MP3 player for the fun of it.
So I am looking for a player where I can solder in some extra GPIO pins besides the usual stop/play/whatever.
These GPIO would be used to drive leds and read extra buttons (the boomblaster will be a bit different).
The plan is not to use the GUI in rockbox rather only use if for playback and get access to the HW platform of the player.
So I will need to modify/add to the FW in rockbox.
Anyone have a tip on good HW platform?
