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.
now able to accept LIBUSB_LOG_LEVEL from commandline to turn on/off error
messges at runtime. Also setting level > 0 will print messages during
device discovery and connection. Still need to permit kazzo firmware
version to be provided on commandline to support K flag.
fixing dictionary call typo with semicolon and setting buffer length
to always be provided with function call instead of dictionary call
deciding what it should be based on the opcode.
Adding some speed notes and other speed related discussions to buffer
dictionary.
Had a good lesson on what static means... :/
everything working now as previously designed
speed testing on windows10 PC yeilded ~21KBps when transferring 128-512KB
payloads and 128Byte transfer size. Going to bump to 256 and see how that
does after 128KB speed tests on linux machine.
created host test.c/.h file for general testing of new features.
that way I can start working on erase/write.h files and just use test.c as
scratch code space for tinkering and still call with -t flag on command
line.
modified dictionary calls to include pointers to data and lengths.
Able to read PRG-ROM flash chip's manf and device ID from commandline.
New dictionaries io and nes along with firmware files to support.
now have io_reset, nes_init, and snes_init io.c functions
nes.c functions including discrete_exp0_prgrom_wr and emulate_nes_cpu_rd.
New dictionary.c/.h for host to make dictionary calls easier including
setting proper return data lengths based on opcode.
adding nop command to pinport.h
