When you press 'CD6' button, does the HU automatically displays 'cd number 6' or is it the rockbox that tells it the number to display? whatever, if you press 'CD6' twice, does the rockbox receive 2 notification of the cd6 button? In this case you just map these actions as standard rockbox buttons. you just have to post an entry in the button_queue. the rockbox will do the rest. this way you have the entire rockbox behaviour through your HU. maybe you could use the talkbox feature also? another advantage is that the buttons are still available and there is no 'cd changer mode' it can cohabit easily. you can look in serial.c and button.c in the firmware dir. > > >>I intend to use the Head unit as a generic lcd display except that it >>has 8 characters...
