Autotune Compile Error

[DavidPHuber]

I confess to knowing NOTHING about coding.
I have built the excellent looking filament jointer project. I am about to start the software side now that I think I have the hardware built correctly.
Upon compiling autotune.ino I get an error "stray '\302' in program" at line 50

I did some research that suggests that I may have gotten a stray space or improper character into the sketch, but I'm unsure how I could have done that.

This is a most interesting project, and I hope I'm getting pretty close to having it functional.
Can you please provide any assistance, or a pointer in the right direction?

I'm sorry if this is happening just because of ineptitude or some skipped step.

Thanks for any assistance you can offer.

I am not sure what is the error about...

I am using Arduino 1.8.12 on Windows 10.

Thinking maybe there was some issue with the upload, I downloaded the ZIP archive from GitHub into a separate folder.

Then I open "autotune.ino" using Arduino, select "Arduino Nano", and click "Verify/Compile". The compilation completed with no error.

Maybe you can follow the steps above and try again?

Or copy/paste entire error log. Maybe there is additional info in there that might tell us what's wrong.

Thank you so much for responding.
Yes. that worked.
I successfully complied and uploaded, but am getting only gibberish from the serial monitor.
I uploaded heater with display just to see if it functioned at all. Nothing.
I suspect I have some wiring incorrect, and am going to review/verify.

THANKS!
I'm so looking forward to getting this one working. what a great idea and great looking implementation.
Thank you for your efforts.

Gibberish from the serial monitor typically means your baud rate on the monitor is different from the baud rate in Serial.begin(). The 2 needs to match.

As with all engineering projects, if the total doesn't work, divide-and-conquer. Break it down into simpler parts and verify that each part works independently. That will greatly increase the chances of working when you put them together.

Good luck!

Hello, I am trying to load the Arduino-PID-Autotune-Library but I get an "Error: 13 INTERNAL: La instalación de la librería no fue exitosa: moving extracted archive to destination dir: library not valid" error.
Also, when I try to compile, after installing the other libraries, I get a "Compilation error: NTC_Thermistor.h: No such file or directory"
Is there any update of the libraries available?I really would like to use these sketches and codes for a PET bottle filament recycling project.
Thanks!
