I have 6 buttons of the HU mapped to the 6 buttons of my archos. Simple
So the protocol and implementation is very very simple.
I have added 4 more actions:
key release (for key repeat implementation)
pause (when switching to tuner)
resume (when switching from tuner)
and power off (when switching off the HU)
the status display is also very simple: I display exactly the same than on
the archos lcd (scrolling included).
I dynamically change the displayed line according to the cursor position.
I also transmit track number and elapsed time separatly.
There is only one poll code, and the rockbox decides what to update by
having a header.
There are actually 2 only possible updates: display and timing.
my code is not hard to port on recorders. it can be also used on generic
external lcd display.
This implementation is the simplest and the most powerful because I have
access to all rockbox functionalities.
I have a power transistor missing for implementing power control from the
haven't modded my archos yet for auto power-on. Hope it won't be too
