PT100 support

[mentaluproar]

Are there any plans to add support for the E3D PT100 kit?

Hi,
No support right now but it's easy, let me see if I can get it done in a few days.

Wow. Thank you.

I implemented support for https://wiki.e3d-online.com/wiki/E3D_PT100_Amplifier_Documentation (I hope I got that right). I updated the online service (www.aprinter.eu) in case you were using that. To configure it, go to Configurations --> your configuration --> Heaters --> heater and set "Temperature Conversion" to "E3D PT100 Amplifier".

Implementation is based on a lookup table with linear interpolation and supports easily adding additional lookup table for other devices (I did not yet have any conversion based on a lookup table). Currently the lookup table has floats so it uses a few hundred bytes of program memory, but that should not be a problem in most cases.

The PT100 amplifier is connected to an analog pin on the RAMPS board, but not the T pins. In my case, it’s on pin A3.

Should not be a problem. The B/T/etc are just definitions in the corresponding Board configuration (Board --> your_board --> Analog Inputs). You can change an existing Analog Input definition (unless it's used for something else already) or define a new one, with the correct pin.

Thanks.  I tried it out but have been unable to get it to compile.  Did I make a mistake with the attached profile?

What is the error? Can you provide the exported configuration file?

[mentaluproar]

The config file is attached to the previous message.  I just got a big long list of errors.

@mentaluproar There is no attachment that I can see.
