Have separate lua modules now in scripts/app folder
Dictionary calls are now their own lua module
firmware now capable of calling multiple different dictionaries
have firmware & lua io and nes dictionaries, able to detect
NES and famicom carts. Created expansion port abstraction so most kazzo
versions behave identically.
Created separate make file for stm adapter and inl6
added PURPLE_KAZZO and GREEN_KAZZO defines back in. They work well enough
for sensing NES vs famicom carts so far. GREEN_KAZZO requires
PURPLE_KAZZO to also be defined. GREEN_KAZZO is also only compatible with
AVR_CORE due to software_AHL/AXL functions specifically written for AVR.
I think things will work if a STM_ADAPTER is placed on a PURPLE_KAZZO and
both those defines are made as only real difference is software tying of
AXL and X_OE. But haven't tested this aside from ensuring it compiles.
Have correction to pinport_al.h that will commit immediately after this.
Effectively deleted old dictionary call function/files.
Created lua_usb_vend_xfr function so lua can directly send and receive
vendor setup transfers.
Dictionary calls are more like function calls now, and all args aren't
required so the LED can be turned on for example in lua like so:
dict_pinport("LED_ON")
general format is:
dict_name( opcode, operand, misc, datastring )
Also added ability to store opcode's return length in shared dict library
files with RL=number in the comments following the opcode.
Negative numbers designate OUT transfers, positive for IN.
Default value can be determined by each dictionary's calling function.
Decided pinport is 1 for SUCCESS/ERROR CODE.
Also have default return data means with second byte giving length of
return data in bytes that follows.
dictionary call function reports any errors reported by the device and
returns any return data from the device excluding error code / data len
Now time to start implementing some of these dictionaries on the device.
packet arrives. Had issue with return data on STM32 not being properly
aligned when the rv array was only 8bit. So defining it as a 16bit array
and then pointing a 8bit pointer to it seems to be an easy fix for now.
Ready to start working on pinport dictionary. Need to get lua code
working on a lower level handling the dictionary calls. Need it do do
things like fill out the wLength and everything for me so one doesn't have
to remember every detail about an opcode/dictionary before calling it.
Realizing code was heavily segmented based on how big/many operands there
were and how big the return data was. This is hard to maintain, need lua
to resolve this issue, and make everything easier to script. Thinking
opcode/dictionary calls need to be more like a function call. Passing in
necessary args only, and returning data instead of succeed/fail.
Things appear to be working with some early testing. Assumption that oper_info elements
are aligned in SRAM linearly appears to hold true. Researching this I found it probably
was true, but can't be certain esp if gets changed in the future to not be purely 8byte
sized elements.
Still need to provide means to decode function numbers info function pointers.
Detecting mirroring code working and tested
Started working on buffer operations from host
Current code compiles but not yet at point where can start testing
Adding cpu page read to nes.c to have faster dumping operations.
moving enums to shared as gets used quite a bit communicating between device and host.
Prepended DICT_ to dictionary names to prevent using those defines for something else accidentally
"NES/SNES" etc could be used in a lot of places, don't want to use wrong enum/define in wrong place.
created enums.h to list out all enums/defines for cartridge and memory elements in one location.
separate file.c/h file for getting data in/out of a files, and opening/closing them.
adding test roms to roms folder so they can be used for various testing.
buffer opcode updates to transfer payloads
including stuffing two bytes of write transfers in setup packet.
Calling specific buffers with miscdata or opcode.
new dump and flash modules for firmware.
new buffer function update_buffers called during main to monitor and
manage buffer objects when not being loaded/unloaded from USB.
Trying to prevent transfer from exceeding buffer size.
Also verifying buffer's status is properly set to enforce upholding of the status.
Giving usbFunctionWrite a means to communicate it's error/success back to host with USB 'dictionary'.
moved all buffer operations out of usb.c with new bridge function between
the two files. Lots of pointing going on and lessons learned..
Thankfully everything seems to be working if you actually call the
functions as I designed them.. Gotta love trouble shooting bugs that
don't exist.. Helped updating allocate output to get returned as error
back to the host.
Moved typedef structs to firmware type.h file as seemed to cause
compilation issues being contained in the files .h file when other .c
files needed those types.
Fixed casting warnings with usbMsgPtr ended up looking at usbdrv.c figured
out how close I got, just shouldn't have been putting the * in there..
complete. should be able to allocate buffers from host, but haven't got
to testing it yet. Compiling on firmware though..
Currently have 256 bytes of raw_buffer, and 8 buffer objects/structs
each with ~16 bytes per object. So could trim things down, but still have
decent amount of SRAM left. Could have another 256 byte buffer at this
rate.. but might not leave enough SRAM for temporary routines.
Possible that raw buffer space could be dynamically allocated
as either buffer space or temporary routine space...

logic 1 if relying on it. Seems to work fine on NES discrete and
INLXO-ROM boards where planning to utilize it. SNES can't pull up due to
pulldown and original famicom cart can't either perhaps because of
EXP6 EXP FF output being too much of a load..?
cleaned up firmware pinport.h used PURPLE/GREEN KAZZO for all #ifdef's

final kazzo design hex commited as comparable build to the past two commits of green/purple.
So this .hex commit is apples to apples with recently commited purple/green .hex commits.
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

new file: host/source/erase.c
new file: host/source/erase.h
creating erase files called from main with e_flag
modified: firmware/source/usb.c
introducing switch statement with range of values of opcode type detection.
modified: host/source/usb_operations.h
turning off debug
modified: shared/shared_errors.h
renumbering some error codes
thinking I'll have codes which can come from avr set to 128+
rearranged some of the .h files, created dictionary file to list all dictionaries of opcodes.
moved error codes to shared file so host can interpret firmware error codes.
created firmware usb.c/h to handle usb operations (didn't move as git seems to think..)
cleaned up fw main function and file.
host usb_operations, created USBrequest struct type to more easily handle all transfer info.
Currently able to send pinport commands and read back return values from retro prog.
Just need to start writting functions to send opcodes and start actually preforming some cartridge operations.
