Initial version that supports the most important
features to operate a DDR SD cabinet with all
inputs and outputs working.
Note that the individual sensor cycling modes are
currently broken. The driver will always set the
sensor read mode to all for now.
With the overhaul of commands, some helpers needed tweaks while
new ones were added to abstract p3io command details with a
common interface, e.g. dealing with the command length field.
Using a real DDR P3IO (Dragon PCB), the overall P3IO command
structures improved significantly. Added further notes about
unknown/unclear commands that were not derivable from the
DDR 18 game binary either.
Note that this module is also used by jubeat to some extend.
The initial design apparently assumed a greater overlap in
commands. This now seems less likely as many commands appear
to be DDR specific.
Refactoring/splitting this is a major effort that is not being
addressed here.
Output the full buffer and the buffer up to the
currently set position. Makes debugging a lot
easier if you know the position set is ok to
only look at the output up to there.
Otherwise, having the full view is also important
to check if data got truncated or checking for
odd looking "garbage" data.
Internally, this was already used but it lacked a clean
public interface to set different log levels from the outside.
Useful for various command line tooling to implement verbosity
levels, e.g. -v, -vv, -vvv
