paul eeepc 497e53378b Basic cartridge detection working. NES detected with CIRAM /CE and PPU /A13N jumper. Famicom detected with audio in/out connection. SNES detected by enabling control signals and reading reset vector looking for non 0xff data. Still need to add check that would pass with blank flash cart though reading flash ID's perhaps.
Removing bad logic where TRUE == 0x00 as that's 'false' in C so that was causing more confusions than solutions.

Paul Molloy 132360f305 Updating main command line input args, and libusb logging/debug messages.
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.

Paul Molloy 2f8823053e making some changes to dictionary call for print options. 2016-12-01 23:15:58 -06:00
Paul Molloy c256ca6b66 testing some bigger transfer sizes removing some printing. 2016-11-30 00:03:40 -06:00
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 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
