Previously, loading default configurations for board or printer,
then modifying them without saving them, then attempting to
build lead to a big mess, like attempting to save the board file,
failing in doing so and then building anyways.
Inserting a dummy value is better than risking an exception with
failure to write a thermistor table at all. Happens when for one
of the usual thermistors accidently a nominal resistance of
1000k instead of 100k is used.
pgm_read_word() was already defined, but pgm_read_dword() did not
get in our way during earlier testing. These functions force the
arduino to read these "defined in program" constant arrays from
"program memory" instead of RAM as a means to save on RAM usage.
The PC-based simulator doesn't need such tricks and only needs to
read the value directly from the in-RAM array. Therefore it is safe
to convert read directly from the pointer being passed.
pgm_read_word() already does this. Define pgm_read_dword()
similarly to it. Fixes#125.
Now it waits for an "ok" before sending the next line, like all
the G-code sending hosts do. This allows sending arbitrarily long
G-codes. The 60 seconds simulated time limit is still in place to
avoid endless simulations.
The standard performance simulation now runs more G-code and
results in slightly different numbers accordingly:

... simply because P is used for many commands and none of them
cares to clean it after usage.
This fixes a bug where setting the default heater without temp
sensor (M106) worked only after a G4 Pxxx command.
... instead of trying to fire an interrupt as quickly as possible.
This affects ACCELERATION_TEMPORAL only. It almost doubles the
achievable step rate. Measured maximum step rate (X axis only,
100 mm moves) is 40'000 steps/s on a 16 MHz electronics, so
approx. 50'000 steps/s on a 20 MHz controller, which is even
a bit faster than the ACCELERATION_RAMPING algorithm.
Tests with temporary test code were run and judging by these
tests, clock interrupts are now very reliable up to the point
where processing speed is simply exhaused.
Performance with ACCELERATION_RAMPING: this costs 10 bytes
binary size and exactly 2 clock cycles per step interrupt or
0.6% performance even. We could avoid this with a lot
of #ifdefs, but considering ACCELERATION_TEMPORAL will one
day be the default acceleration, skip these #ifdefs, also
for better code readability.

It's rarely a good idea to overwrite files coming with a
distribution. Not for users, because they can't reset to factory
values; not for developers, because Git would pick up such changed
files.
Instead we read from configtool.default.ini now, but write to
configtool.ini. If configtool.ini is already present, it's
prefered over configtool.default.ini.
It's also possible to do this by stringifying MCU, but this
requires double redirection, which isn't easily readable in a .c
file. For stringification, see the bottom example at
https://gcc.gnu.org/onlinedocs/cpp/Stringification.html
- "Traumflug" and "Markus Hitter" are the same, mention him only
once.
- Add more common F_CPU choices in comments.
- Hint to another choice in Makefile-example.
It was so far unnoticed that the "simulavr" program is only a
script when run from within the build directory. Still killing it
by name worked, because bash's exec didn't terminate the initiating
script.
Apparently this week Ubuntu updated bash and the new version now
terminates the initiating script (which is a good idea), but now
the executable to kill by name has a different name. It's prefixed
with "lt-". As this "lt-" is hardcoded we can rely on it.
Forgotten in commit 74808610c7,
"DDA: Move axis calculations into loops, part 5.".
This and the previous commit makes ACCELERATION_TEMPORAL building
(and working!) again.
Next time, please at least try to compile the code section in
question when explicitely changing the section. In this case,
with ACCELERATION_TEMPORAL enabled. It didn't build.
Was broken with commit 95926a3f113809bde8ff0c84b94c55c73e398f67,
"DDA: Rename confusing variable name.".
Original author @triffid about these files:
"The idea was to be able to program another board from your
electronics without PC intervention, but reprap never seemed
to go down that road."
Should solve Issue #115.
As they're all converted, they're no longer of any use. Still
they were kept up to this commit to allow comparisons between
old and new config.h system.
Likely users don't care too much about the name of the saved file,
so they likely use the default ones. If they mess up, they also
likely want to return to the original, but, d'oh, it's overwritten.
Don't let this happen, enforce a non-original file name for user
saves.
In other words: don't let users shoot themselfs into their foot.
It was certainly a good idea, but also always a suspect of
malfunctions and as such, almost never used. Newer code
organisation moves most of the code behind it to dda_clock()
anyways, so it also became mostly obsolete.
Rest In Peace, STEP_INTERRUPT_INTERRUPTIBLE, you were matter
of quite a number of interesting discussions and investigations.
