In interactive mode, reset the address and length if we start dumping
a memory type different than the previous one.

Allow instruction data to be specified more flexibly, which can be
used to make the instruction input more readable in the config file.

* Makefile, avr.c, avr.h, avrdude.conf.sample, config.c, config.h:
* config_gram.y, fileio.c, fileio.h, lexer.l, main.c, term.c:
This is a major re-write of the programming algorithms. The Atmel
serial programming instructions are not very orthoganal, i.e., the
"read fuse bits" instruction on an ATMega103 is an entirely different
opcode and data format from the _same_ instruction for an ATMega163!
Thus, it becomes impossible to have a single instruction encoding
(varying the data) across the chip lines.
This set of changes allows and requires instruction encodings to be
defined on a per-part basis within the configuration file. Hopefully
I've defined the encoding scheme in a general enough way so it is
useful in describing the instruction formats for yet-to-be invented
Atmel chips. I've tried hard to make it match very closely with the
specification in Atmel's data sheets for their parts. It's a little
more verbose than what I initially hoped for, but I've tried to keep
it as concise as I could, while still remaining reasonably flexible.
2001-11-19 Brian S. Dean <bsd@bsdhome.com>
* avr.c, avr.h, avrdude.conf.sample, main.c, ppi.c, term.c:
Add support for ATMega163.
Add support for reading/writing ATMega163 lock and fuse bits.
Unfortunately, in looking at the specs for other ATMega parts, they
use entirely different instruction formats for these commands. Thus,
these routines won't work for the ATMega103, for example.
Add support for sending raw command bytes via the interactive terminal
interface. This allows one to execute any programming instruction on
the target device, whether or not avrprog supports it explicitly or
not. Thus, one can use this feature to program fuse / lock bits, or
access any other feature of a current or future device that avrprog
does not know how to do.
Add in comments, an experimental instruction format in the
configuration file. If this works out, it would allow supporting new
parts and non-orthoganal instructions across existing parts without
making avrprog code changes.
2001-11-17 Brian S. Dean <bsd@bsdhome.com>
* avrdude.conf.sample: Add ATMEGA163 part.

2001-10-31 Brian S. Dean <bsd@bsdhome.com>
* avr.c, avrdude.conf.sample, main.c: Correct version string.
Update read/write status more frequently.
Prefix ATMega parts with an 'm'.
2001-10-16 Brian S. Dean <bsd@bsdhome.com>
* avr.c: Change ording for memory display.
* config_gram.y: comment
* avr.c, avr.h, avrdude.conf.sample, config_gram.y, lexer.l, term.c:
Fix (again, hopefully) page addressing for the ATMega parts.
Rename the poorly chosen name "bank" to "page" for page addressing.
Atmel calls it "page" in their documentation.
* config_gram.y, main.c: Fix an (non)exit.
Silence a couple of compiler warnings.
* avr.c, avr.h, avrdude.conf.sample, config_gram.y, main.c:
Fix ATMega flash addressing. Add an ATMEGA16 part. Perform sanity
checking on the memory parameters for parts that do bank addressing.
2001-10-15 Brian S. Dean <bsd@bsdhome.com>
* config.c, config.h, lists.h: Add copyright.

Try and detect an old-style config file and print an appropriate error
message and a suggestion for correcting it.
* Makefile, avr.c, avrdude.1, avrdude.conf.sample: Update the man page.
Miscellaneous minor cleanups.
2001-10-14 Brian S. Dean <bsd@bsdhome.com>
* Makefile, Makefile.inc, avr.c, avr.h, avrdude.conf.sample:
* config.c, config.h, config_gram.y, lexer.l, lists.c, lists.h:
* main.c, pindefs.h, term.c:
Use lex/yacc for parsing the config file. Re-work the config file
format using a more human-readable format.
Read part descriptions from the config file now instead of hard-coding
them.
Update usage().
Cleanup unused code.
* Makefile, avr.c, avr.h, fileio.c, term.c:
First cut at supporting the ATmega 103 which uses bank addressing and
has a 128K flash.
Due to the bank addressing required, interactive update of the flash
is not supported, though the eeprom can be updated interactively.
Both memories can be programmed via non-interactive mode.
Intel Hex Record type '04' is now generated as required for outputing
memory contents that go beyond 64K.

Update copyrights.
2001-09-21 Brian S. Dean <bsd@bsdhome.com>
* main.c:
Be sure to read the exit specs after the pin configuration has been
assigned, otherwise, we may apply the exit specs to the wrong pins.
* main.c: debugging
2001-09-20 Brian S. Dean <bsd@bsdhome.com>
* avrdude.1, avrdude.conf.sample, main.c:
Prefix pin config entries in the config file with a "c:". Later, I
might make part descriptions read in this way and we can use a
different letter for those (p). This will make the parsing easier to
distinguish between the entry types.
* main.c: Initialize pin configuration description.
2001-09-19 Brian S. Dean <bsd@bsdhome.com>
* AVRprog.pdf, Makefile, avr.c, avrdude.1, avrdude.conf.sample:
* avrdude.pdf, fileio.c, fileio.h, main.c, pindefs.h, term.c:
Make the pin definitions configurable based on entries in a config
file. This makes supporting other programmers much easier.
Rename AVRprog.pdf to avrprog.pdf.
2001-04-29 Brian S. Dean <bsd@bsdhome.com>
* avrprog-programmer.jpg: Remove this image file from the repository.
2001-04-26 Brian S. Dean <bsd@bsdhome.com>

Remove this image, use AVRprog.pdf as the preferred schematic for the
programmer.
2001-04-25 Brian S. Dean <bsd@bsdhome.com>
* AVRprog.pdf, Makefile, avrdude.1:
Add a schematic provided by Joerg Wunch and also update the manual
page (also updated by Joerg) to reference the schematic.
2001-02-25 Brian S. Dean <bsd@bsdhome.com>

term.c : update status leds on write, make the address and length
arguments for dump optional.
2001-01-26 Brian S. Dean <bsd@bsdhome.com>
* main.c: Version 1.1
* main.c:
Hmmm ... cvs co -D <timestamp> does not work. Change the revision
timestamp to a full date/time value.
* avr.c, fileio.c, main.c, ppi.c, term.c:
Add a -V option to display the version information about each
component module. This is intended for support purposes, so that I
can tell unambiguously what version a binary out in the field is.
Additionally, display a revision timestamp along with the version
number. This also is intended for aiding in support and is the Unix
time of the latest component module. Having this, should allow me to
do a "cvs co -D timestamp avrprog" and get exactly the source of the
version that is being reported.
* fileio.c:
Return the maximum address (+1) written as opposed to the actual
number of bytes written. The presence of an Intel Hex address
record can cause these two number to be different; but the callers
of this routine need the former.
* main.c:
Fix a place where we were exiting without applying the exit-specs.
Wrap a long line.
* avr.c, fileio.c: avr.c: Update a comment.
fileio.c: Properly handle all the Intel Hex record types that I can
find information about.
2001-01-25 Brian S. Dean <bsd@bsdhome.com>
* Usage, avr.h: Get rid of the Usage file.
2001-01-24 Brian S. Dean <bsd@bsdhome.com>
* Makefile, avr.c, avr.h, main.c, pindefs.h, ppi.c:
Move pin definitions to their own file.
First pass at providing feedback via the optionally connected leds. I
don't actually have any of these attached to my programmer, so I can
only guess as whether this is toggling them on and off correctly.
Also, enable and disable the optional 74367 buffer.
* avr.h, main.c, ppi.c, ppi.h, avr.c:
Rearrange the pinout for the programmer to be a little more logical.
Provide hooks to support a buffered programmer, pin 6 is now used to
enable a buffer that can be used to isolate the target system from the
parallel port pins. This is important when programming the target
in-system.
Totally change the way the pin definitions are defined. Actually
set/clear pins based on the way more intuitive pin number, instead of
PPI data register, bit number combination. A table of pin data is
used so that any hardware inversion done by the parallel port is
accounted for, what you set is actually what appears at the pin.
Retain the old method for handling Vcc, however, because the hold
method is much easier to use when setting / retrieving multiple pins
simultaneously.
2001-01-22 Brian S. Dean <bsd@bsdhome.com>
* Makefile: Don't gzip the man page.
* avrdude.1: .Nm macro fix. Submitted by Joerg.
* main.c: Cosmetic, don't output a preceding linefeed for usage().
* Makefile, avr.c, avr.h, fileio.c, term.c:
Makefile : use gzip -f for man page installation so that we don't get
prompted.
avr.c avr.h fileio.c term.c :
Change the avrpart data structure so that the typedef AVRMEM is
used as an index into an array for the sizes of the memory types
and also for pointers to buffers that represent the chip data for
that memory type. This removes a lot of conditional code of the
form:
switch (memtype) {
case AVR_FLASH :
...
}
Also, re-code avr_read_byte() and avr_write_byte() to properly
handle the flash memory type without having to tell them whether
they should program the high byte or the low byte - figure that
out from the address itself. For flash memory type, these
routines now take the actual byte address instead of the word
address. This _greatly_ simplifies many otherwise simple
operations, such a reading or writing a range of memory, by not
having to worry about whether the address starts on an odd byte
or an even byte.
2001-01-20 Brian S. Dean <bsd@bsdhome.com>
* avr.c, avr.h, fileio.c, fileio.h, main.c:
Return error codes instead of exiting, thus making sure that we exit
only via main() so that the exitspecs are properly applied.
When reading input data from a file, remember how many bytes were read
and write and verify only that many bytes.
Don't complain when an input file size is smaller than the memory size
we are programming. This is normal.
* fileio.c:
Correct checksum calculation; failure to account for the value of the
record type was causing non-zero record types to be calculated
incorrectly.
* Makefile, main.c: Makefile : install the man page
main.c : drop the giant usage text now that we have a man page.
* avrdude.1:
Add initial man page graciously contributed by Joerg Wunsch. Thanks
Joerg!
2001-01-19 Brian S. Dean <bsd@bsdhome.com>
* term.c:
Accept abbreviations for eeprom and flash for the dump and write
commands.
Fix small bug keeping 1 character command lines from being added to
the history.
* term.c:
Implement enough state in cmd_dump so that if it is called with no
arguments, it successively dumps the next chunk of data of the same
previously specified length.
* term.c, term.h, fileio.c, fileio.h, main.c, ppi.c, ppi.h:
* Makefile, avr.c, avr.h, avrprog.c:
The program was getting too large for a single file. Split it up into
more modular pieces.
Also, accept command abbreviations as long as they are not ambiguous.
* avrprog.c:
Add ability to specify the state of the power and reset pins on
program exit. Default to leaving the pins in the state they were when
we found them.

2001-01-18 Brian S. Dean <bsd@bsdhome.com>
* Makefile, avrprog.c:
Switch to using readline() for getting terminal input. I can't seem
to get the history capabilities working yet, but even so, it does
better handling of the prompt and strips newlines for us, so it's
still a win.
Add a few new commands for terminal mode: help, sig, part, erase.
Display rudimentory help using the help command.
Add some function prototypes.
* Usage, avrprog.c:
Change -c (interactive command mode) to the more intuitive -t
(terminal mode).

* avrprog.c:
Use a smarter programming algorithm - read the existing data byte
first and only write the new one if it is different.
Add -n option which is a test mode in which the chip is not actually
updated. This option does not affect writes in interactive mode.
* avrprog.c: Add the "dump" and "write" interactive commands.
* avrprog.c:
Correctly produce and handle "end of record" for intel hex files.
2001-01-13 Brian S. Dean <bsd@bsdhome.com>
* avrprog.c:
Re-enable writing to the chip. I should probably should make this a
command-line selectable option so that I don't keep forgetting and
committing it with it disabled.

Add a newline before exiting due to command line errors. Perform a
bit more option compatibility testing between -c, -i, and -o.
* avrprog.c: Add input file format auto-detection support.

Clean up debugging code a little, utilize fileio() instead of making
direct calls to b2ihex().
* avrprog.c: A lot of general code cleanup.
Re-work command line options to be more intuitive.
Support Intel Hex input and output file formats. Provide hooks to
support Motorola S-Record as well.
Add a few more part-specific parameters to the avrpart structure.
Only write the flash or eeprom if the data to be written is not 0xff.

Bring RESET low when programming is completed.
* avrprog.c:
Correct pin connection comments. Elaborate a bit on Vcc connection.
* avrprog.c:
Update after receiving some good feedback from Joerg Wunsch. We
should now be able to program AT90S1200's.
2000-12-30 Brian S. Dean <bsd@bsdhome.com>

Eliminate debug print facility.
Provide 'avr_cmd()' function.
When memory locations don't program, generate a newline so that the
