Previously some features were excluded based on whether SIMULATOR
was defined. But in fact these should have been included when __AVR__
was defined. These used to be the same thing, but now with ARM coming
into the picture, they are not. Fix the situation so AVR includes are
truly only used when __AVR__ is defined.
The _crc16_update function appears to be specific to AVR; I've kept the
alternate implementation limited to AVR in that case in crc.c. I think
this is the right thing to do, but I am not sure. Maybe ARM has some
equivalent function in their libraries.
For now this is just a nice demonstration on how to send bytes
over SPI. Add SD_CARD_SELECT_PIN to your configuration board
file manually to see data signals on MOSI dancing on the scope.
The TODO's about SS in arduino*.h were wrong, SS does have a
chip-specific special meaning (used in SPI multi-master or SPI
slave mode). Still, a #define MAX6675_SELECT_PIN is missing.
Squashed in this commit from the SPI development topic branch to
get this first step working:

mendel.c: disable SPI in power management only when not needed.
If we want to talk to a SD card connected to SPI, we need SPI
powered, of course.
From Traumflug: nice catch, Jeff!
Order of heater and temperature sensor can differ, so they can get
different numbers. When printing extruder temperatur, we want to
print the temperature of the sensor matching the extruder heater,
not that of the temp sensor with the same number as the extruder
heater. Same for the bed respectively.
This should partially solve issue #96.
Problem spotted, described in a helpful manner and over-fixed
by @zungmann. This fix picks up his basic idea and implements it
with already existing state properties.
Test code which wants to customize config.h can do so without
touching config.h itself by wrapping config.h in a macro variable
which is passed in to the compiler. It defaults to "config.h" if
no override is provided.
This change would break makefile dependency checking since the selection
of a different header file on the command line is not noticed by make
as a build-trigger. To solve this, we add a layer to the BUILDDIR path
so build products are now specific to the USER_CONFIG choice if it is
not "config.h".
This code was accidentally removed long ago in a botched merge. This
patch recovers it and makes it build again. I've done minimal testing
and some necessary cleanup. It compiles and runs, but it probably still
has a few dust bunnies here and there.
I added registers and pin definitions to simulator.h and
simulator/simulator.c which I needed to match my Gen7-based config.
Other configs or non-AVR ports will need to define more or different
registers. Some registers are 16-bits, some are 8-bit, and some are just
constant values (enums). A more clever solution would read in the
chip-specific header and produce saner definitions which covered all
GPIOs. But this commit just takes the quick and easy path to support my
own hardware.
Most of this code originated in these commits:

Add simulation code: use "make sim"
Additional tweaks:
Revert va_args processing for AVR, but keep 'int' generalization
for simulation. gcc wasn't lying. The sim really aborts without this.
Remove delay(us) from simulator (obsolete).
Improve the README.sim to demonstrate working pronterface connection
to sim. Also fix the build instructions.
Appease all stock configs.
Stub out intercom and shush usb_serial when building simulator.
Pretend to be all chip-types for config appeasement.
Replace sim_timer with AVR-simulator timer:
The original sim_timer and sim_clock provided direct replacements
for timer/clock.c in the main code. But when the main code changed,
simcode did not. The main clock.c was dropped and merged into timer.c.
Also, the timer.c now has movement calculation code in it in some
cases (ACCELERATION_TEMPORAL) and it would be wrong to teach the
simulator to do the same thing. Instead, teach the simulator to
emulate the AVR Timer1 functionality, reacting to values written to
OCR1A and OCR1B timer comparison registers.
Whenever OCR1A/B are changed, the sim_setTimer function needs to be
called. It is called automatically after a timer event, so changes
within the timer ISRs do not need to bother with this.
A C++ class could make this requirement go away by noticing the
assignment. On the other hand, a chip-agnostic timer.c would help
make the main code more portable. The latter cleanup is probably
better for us in the long run.
The requirement was simply neither obvious nor intuitive. Drawback
is, the indices of temperature sensors can now differ from these
of the heaters. That's easier to recognize for newbies, though.
Saves 10 bytes RAM and 16 bytes binary size on an 1284P (8 ADC
channels) running two sensors. Should also be a bit faster, as one
loop runs fewer iterations.
Also, checking for NUM_TEMP_SENSORS was a mistake, as temp sensors
_not_ using an analog pin exist. Extreme case is, temp sensors
exist, but zero ADC channels are used.
Remove the assumption there's always an extruder temperature
sensor and make reading on single sensors (e.g. M105 P2) more usable.
Apparently works very well, but *sigh* yet another 100 bytes of binary size.
This is useful when operation a milling spindle. In this case,
set the spindle speed with M104 Sxxx, where xxx is 1..255.
M104 S0 turns the spindle off.
& tests of the debug_flags. Currently the compiler is able to eliminate
the block and the & operation when the constant is zero, but since
the debug_flags variable is a volatile the compiler does not eliminate
the load of the variable. By pretesting and shortcutting the load is
eliminated. Saves a small number of bytes when the debug build is
disabled and costs nothing when it is enabled.
Two thermistor tables included:
ThermistorTable.h.dist.old, which is the table we used to have, included so those already using it don't have to recalibrate.
ThermistorTable.h.dist, which was generated with 50 entries, and trimmed down in lower temperature ranges where we don't care as much about accuracy and there's less deviation from a straight line anyway.
Corrected default temp sensor entry in config.h.dist to thermistor instead of intercom. (Now matches earlier definitions which by default say we're using a thermistor)
Added noheater sensor example to config.h.dist
Copied CreateTemperatureLook.py from "official" firmware, and modified it for 14.2 fixed point, no negative temperatures (we're using uint16_t's), and PROGMEM.
Since I simply copied the example linear interpolation formula from wikipedia, I'm certian that it could be more efficient. The code that was there wouldn't work with 14.2 table values, and my understanding of it was too shallow to fix it. This works, and upgading the calculations to uint32_t actually takes less code space than leaving them at uint16_t. I assume it's calling a library routine that's already being linked in for the 32-bit math.
