paul eeepc a89caf2454 Detecting some flash carts including NROM and UNROM.
Using CHR-RAM sensing, and flash manf/prod ID based on PRG-ROM banking

fixing bug in firmware for ppu writes was ANDing in /A13 instead of ORing..

adding datasheets to hardware folder for 5v PLCC and 3v TSOP flash used on all flash boards

paul eeepc d97c31db62 Determining overall operation READ/WRITE. 2016-12-07 19:19:34 -06:00
paul eeepc 66635b15e7 Making progress on main program flow with detection in preparation for dumping/writing operations.
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.

paul eeepc a24d728cea flashing page working, verified by reading back again.
currently instruct buffer to dump/flash by setting its function accordingly

Paul Molloy 3326c2fb34 payload buffers working with some early testing.
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.

paul eeepc cb0941e86c usbFunctionWrite support loading incoming write/OUT data to buffer objects.
Still untested, need to write some host code to test things out.

Paul Molloy 80943f7f62 firmware buffer.c reorganization and some intitial testing complete.
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..

Paul Molloy c6a68c679f Adding EXP0_PULLUP_TEST should probably verify pullup on EXP0 provides
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..?

paul eeepc cd6378b8c5 SNES dictionary creation, addition of NES cpu/ppu read/writes
cleaned up firmware pinport.h used PURPLE/GREEN KAZZO for all #ifdef's

AVR Memory Usage
----------------
Device: atmega164a

Program:    3404 bytes (20.8% Full)
(.text + .data + .bootloader)

Data:         53 bytes (5.2% Full)
(.data + .bss + .noinit)

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.

Paul Molloy 7d00145431 Big step in confirmation of pin manipulations working on kazzo.
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

	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+
