Now lua scripts can make usb dictionary calls based off of C shared_dict*.h files.
Don't have to have separate lua tables for host, and C #defines for firmware to keep things aligned!
Tested and working on all current shared_dict*.h files including some simple error checking.
Does not permit multi-line comments, but inline is fine and properly accounted for.
defines starting with underscore are skipped to not trip up header define guard statement.
defines can't be set to other defines, macros, or math, only a decimal/hex number.
Tested and able to turn on/off/ip/op LED on kazzo.
Currently have redefined table that needs to align with shared dictionary
files.
Next task is to parse shared dictionary files to create tables at runtime.
scripts/usb_device.lua is planned to use for usb device info prior to
connecting. Currently just used to determine log level.
scripts/inlretro.lua is the main script called by the C main function.
Prior to passing control over to lua in inlretro.lua, commandline args
must be passed in somehow. And the USB device must be connected to, and
usb transfer object passed to dictionary's local transfer pointer.
Not sure dictionary having a local static pointer to usb transfer struct
is a great idea, but simplest solution I could think of to keep from
complicating lua by passing the pointer/object back and forth between lua
and C. This method mostly abstracts the usb transfer object from lua
which makes sense to me anyway.
Need to come up with a way for shared_dict_*.h defines to be made
available to lua scripts. Seems a lua table would be the best solution,
but don't want to keep manual copies for all the defines. These C defines
are necessary as it's the only clean way to define the dictionaries for
the firmware. Thinking the best solution will be a lua script that
parses all shared_dict*.h files and creates tables at run time. Planning
to hardcode some tables for now, then implement a .h file parser in lua.
