Error when uploading to Arduino R3

[averagenokiauser]

Hi, I am getting these errors when trying to upload the code to Arduino Uno R3:
/var/folders/2f/n704ym951790x1np_pr8jrvr0000gn/T//cczhQTfa.ltrans0.ltrans.o: In function main': /Users/user/Library/Arduino15/packages/arduino/hardware/avr/1.8.6/cores/arduino/main.cpp:43: undefined reference to setup'
/Users/user/Library/Arduino15/packages/arduino/hardware/avr/1.8.6/cores/arduino/main.cpp:46: undefined reference to `loop'
collect2: error: ld returned 1 exit status

exit status 1

Compilation error: exit status 1
Does anyone know how to fix this?

What tools / IDE are you trying to use? loop and setup are part of the Arduino framework, so it seems like that might be missing or misconfigured.

Google might be a good source of answers for this one.

Thanks for the quick reply, I am using Arduino IDE 2.3.2 on Mac OS. I also tried some older versions of IDE and its the same. I even tried running it on Linux and its also the same. About the tools I installed TimerOne if that's what you mean with tools. Sorry I got the Arduino today so I don't know much about it right now.

Did you open only the .ino file in the IDE, or have you opened other files? Sometimes it gets weird if you try to open anything but that one file.

[averagenokiauser]

I opened the Moppy2-Arduino.ino file that is in folder Moppy2-Arduino.

[averagenokiauser]

Okay, so I tried adding void loop(){} and void setup(){} to the code as someone said and now it seems to upload it without any problems. Will it work okay with this code added or not?

[averagenokiauser]

When I click the reset button nothing happens. Its probably because of that piece of code I added. Also where exactly do I connect ground wire on the floppy drive? Right now its on pin 31 as on wiki it says to connect it to a odd number pin.

Okay, so I tried adding void loop(){} and void setup(){}

It's weird that this helped as loop() and setup() are already defined here. When you say "to the code" what file did you add it to?

Did you unzip the release after downloading it and open the .ino from the unzipped directory?

It sounds like the code you've added essentially says "do nothing" for setup and loop, and it sounds like that's what it's doing. Best to remove the changes and figure out why the IDE isn't finding the actual code.

Also where exactly do I connect ground wire on the floppy drive?

Pin 31 should probably be fine (but you could also use the odd numbered pin across from one of the in-use pins just to be sure). 17 or 19 might be a safer bet in case the particular drive you have isn't using 31 for some weird reason.

I added that code to Moppy2-Arduino.ino file. Yes I unzipped the release.

[averagenokiauser]

This is how the unzipped folder looks like for me.

[averagenokiauser]

Is it normal that I get this error when opening the file?

[averagenokiauser]

Found the issue! You just need to rename release zip to Moppy2-Arduino after downloading and it will work.

[samphonic]

Ohhhh, well there you go. And it was actually like that automatically until 2.1.1 where I guess I messed that up. I'll see if I can fix the release zip. Good catch!

[samphonic]

Fixed the release binary. Thanks again. If you get the rest working feel free to close this issue (or come back if there's something else you've got a question about)

[averagenokiauser]

No problem! Few more questions: do I need to change the config if I wire more than one floppy drive? If yes I then need to upload the code again right? Also can I connect more floppy drives to the same ground pin?

[samphonic]

Not at my computer, but IIRC the config is set for 8 drives out of the box, so you're good for at least that many. All the grounds can be connected together (daisy chained or star should both work fine for this application)
