Marlin: Where is TEMP_CHAMBER_PIN?

[ghost]

Hello.
TEMP_SENSOR_CHAMBER is in the Thermal Settings section.
However, the Pins.h has no setting like TEMP_CHAMBER_PIN.
It only has TEMP_ 0 - 4_PIN and TEMP_BED_PIN.
Where can I set the pin for the chamber sensor?

You can define it in your Configuration.h file.

@thinkyhead In Configuration.h file is TEMP_SENSOR_CHAMBER.
This is to specify type of temperature sensor to use.
There is no way to define which pin the temperature sensor is connected to.
Similarly, the Configuration_adv.h file can define the pin of cooling fan, but there is no pin definition of temperature sensor.

There is no way to define which pin the temperature sensor is connected to.

Just add a line like this to Configuration.h, specifying the pin you've connected it to:

#define TEMP_CHAMBER_PIN 12

Thank you for teaching me.
I tried and I got a compile error.
This is the result of using the latest version of Marlin 2.0.x with Arduino Due.

Test1:
Delete #define TEMP_2_PIN 3 from pins_RAMPS_FD_V1.h.
Add pin settings to the Configuration.h. #define TEMP_CHAMBER_PIN 3

   if (pin_is_protected(pin_number)) return protected_pin_err();
                        ^

Test2:
Restore pins_RAMPS_FD_V1.h.
Add pin settings to the Configuration.h. #define TEMP_CHAMBER_PIN TEMP_2_PIN

Grab the newest bugfix-2.0.x code which has those errors patched.

I compiled successfully with the latest version.
Thanks a lot.
