When building with GCC 4.9.2 (bundled with PF-build-env-1.0.6.*), -Os
and LTO enabled, PID_autotune gets automatically inlined into
process_commands().
Sadly, due to the massive size of process_commands(), it results in
codegen bug doing a partial stack overwrite in process_commands()
itself, manifesting as random behavior depending on the timing of
interrupts and the codepath taken inside the merged function.
Mark the function as noinline and add a note about the affected compiler
version in order to be checked again in the future.
This avoids the "busy" output interleaving with regular output in very
rare scenarios.
We should focus in finding which calls are not using manage_inactivity()
properly instead of working it around.
Now that the stack_error function is truly minimal,
we can check for stack errors much more frequently.
Also move away stack_error from ultralcd to Marlin_main.
- Changed DETECT_SUPERPINDA to SUPERPINDA_SUPPORT as on miniRAMo the thermistor readings below 30°C
aren't accurate egnough to determine if SUPERPINDA is connected or not
- Add LCD toggle menu Settings -> HW Setup -> SuperPINDA [Yes/No] to overwrite SuperPINDA detection
- If EEPROM_PINDA_TEMP_COMPENSTATION is empty = 0xff then detect SuperPINDA by checking thermistor
- If EEPROM_PINDA_TEMP_COMPENSTAION is 0 then forec enable for temperature compensation menues and functions
- If EEPROM_PINDA_TEMP_COMPENSATION is 1 then force disable for temperature compensation menues and functions
The temperature and fsensor ISR re-enable interrupts while executing.
However, we still need to protect the epilogue of the ISR so that
the saved return address is not altered while returning.
We hoist the body of the function out of the isr in both cases for
clarity (and to avoid a stray return bypassing the lock/cli), so that
the re-entrant portion is clearly indicated.
This should fix the "STATIC MEMORY OVERWRITTEN" error messages randomly
happening when stepping at high frequency (where either isr is
preempted more frequently).
Factor-out MIN/MAXTEMP [BED/AMB] out of the error message, which is now
built at runtime instead.
Introduce two missing ultralcd functions lcd_setalertstatus and
lcd_updatestatus to handle regular strings.

Partially revert 285b505c73a54e9af01816e3a614de73ad181851 so that
we ensure heaters are disabled ASAP in case of potential bugs
in the max_*_error functions.
Take advantage of the NTC thermistor found on the Einsy as an additional
safety measure, following the steps of the other MIN/MAXTEMP errors.
Introduce two configurable params AMBIENT_MINTEMP and AMBIENT_MAXTEMP
in the variant defines and set them for the MK3/MK3S to -30/+100
respectively.
AMBIENT_MINTEMP is primarily intended to catch a defective board
thermistor (to ensure MAXTEMP would be properly triggered) and thus the
trigger temperature is set just above the sensing limit and well below
the operating range.
AMBIENT_MAXTEMP is set at 100C, which is instead 20C above the maximum
recommended operating temperature of the Einsy. The NTC thermistor is
located just above the main power connector on the bottom of the board,
and could also help in detecting a faulty connection which can result in
rapid overheating of the contacts.
As for MAXTEMP, we cut power to the heaters, print fan and motors to
reduce power draw. Resume is not possible except by resetting the
printer, since the user is highly advised to inspect the board for
problems before attempting to continue.
In max/min_temp handlers remove the redundant disable_heater() call.
Handlers already need to call Stop(), which will disable all heaters
as the first step.
Fix comments in order to mention that all heaters get disabled.
Use "MAX/MINTEMP BED" correctly in both the LCD and serial.
* MK3S IR sensor detection and safe operational range fix
* debug, change of fsensor_IR_check behavior
* more doc + disable debug print voltage
* fix displaying MSG_04_OR_NEWER and MSG_03.... kudos to @ovariludovit
* better handling of fsensor not responding scenario
