ControlGUI

[JE521]

Hi, I know moppy is really old, but i was interested. I am on pc. I followed the directions on the wiki, but when I am supposed to open the "MoppyControlGUI.bat", (I was given the prompt to agree to run it) , it opens for a millisecond and then closes. The Hardware and arduino set up worked fine, and i am using moppy 2.0.1. If you could help that would be much appreciated. Thank you

[Sammy1Am]

Replying by email so excuse the brevity (I can try more later if this doesn't help):

Instead of double clicking the .bat, try opening the command line (Start>run>cmd) and running the bat from there. It'll show any errors that occur hopefully.

Also look around in the Moppy folders for log files that might have errors.

Maybe try before unzipping, right clicking, properties, and check "unblock", then unzip.

If it's still not working, or there's an error, let me know and I'll respond at length later.

Good luck!

Thank you for responding. I copied the text contents of the .bat file and pasted it in command prompt. I hop thats what you meant. but it did the same thing. I also unblocked it. when i clicked on it, it would pull up a window and had the options "extract all", "Run", and "Cancel". I clicked run, did the same thing. I extracted all and it just made another duplicate moppycontrolGUI folder.

I also noticed in the wiki, it has no mention of netbeans, is netbeans not required anymore?

[Sammy1Am]

Alrighty, back home and in front of a computer now.

It sounds a bit like it's probably a Java-related issue, but it's hard to say for certain what it is without a little more info. There's some things to try below that will hopefully give you a more specific error message so you can figure out what's wrong, but you may also want to try reinstalling Java, or installing a different version of Java. Also confirm that Java is in your user's PATH.

When you say "it opens for a millisecond and then closes", are you actually seeing a Java UI (gray/white window) show up for a second, or are you just seeing a command prompt (black window) show up?

Instead of copy-pasting the .bat file, try this:

1. Go to the folder where the .bat file is.
2. In the location/address bar at the top (the bit that says, C:\Users\You\Downloads or whatever), type cmd. This should open up a command prompt already in that directory.
3. Type MoppyControlGUI.bat and hit enter.

What happens? Are there any errors shown in the command terminal? And did you have any luck finding any .log files in the Moppy folders after attempting to launch the GUI?

NetBeans is no longer required just to run Moppy. You can still use it to modify and build your own copy of the source code, but if you're just looking to use it as-is it's not required.

[JE521]

an error message shows up when i run it via terminal, it is: "ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.

Please set the JAVA_HOME variable in your environment to match the location of your Java installation." And I could not find any .log files.

When the window opens for a millisecond and closes, it opens on the terminal.

Also i do not know what you mean by confirming java is in my user's path. I have JDK version 12.0.2, and i have a java folder on my program files folder. i also have a folder named file folders (x86) which does not have java in it. I can confirm java works because minecraft java works on my pc.

thanks again for helping me

[Sammy1Am]

I'll refer to you to Google for setting JAVA_HOME in your particular environment since it varies a bit sometimes. Just get JAVA_HOME set correctly and you should hopefully be good to go.

[JE521]

Thank you it works. but i have one more question? Is it possible to run moppy with a 3 1/4" floppy drive and a 5 1/2" floppy drive. I am using a 3 1/4" floppy. Also how would I go about adding more floppies? thank you so much for your help.

[JE521]

I meant 5 1/4" floppy drive

[Sammy1Am]

Yup, 5.25" drives work just fine (though some of them may have less tracks, so you'll need to adjust the maximum position for those drives in the Arduino code (to 79 instead of 158)).

You can add up to 9 floppies by just connecting them to the next available pair of pins (e.g. 2&3, 4&5, &c.).

[JE521]

Do you have a pinout diagram by chance? I can't seem to find it in its manual.

[Sammy1Am]

5.25" drives, I believe, have the same pin ordering as the 3.5" drives, just a different connector type.

[JE521]

I am working on the connections, but how do I change the max position for any of the drives. I checked the code and couldn't find any variable for the max position. Also is it ok to connect all of the drive's ground pins to the same ground pin on the arduino. I doubt it but I don't see much different ground pins on the arduino.

[JE521]

the drive does not work, is it possible to control the stepper by directly connecting it to the arduino. I looked online and in your previous issues but can not find anything. Thanks again so much for your guidance.

[JE521]

I also can not seem to run the working floppy on any of the other pins for additional drives, i was checking to see if it worked and it didn't.

[Sammy1Am]

GitHub has a useful search function to find things in a repository.

It's not possible to control the stepper motor directly from the Arduino (there is some circuitry required to drive stepper motors, but it's conveniently included in the floppy drive hardware which is why floppy drives work so well). It is possible to drive stepper motors directly using Moppy, but you'd need a driver board connected to the Arduino to do so.

Make sure the MIDI file you're using has enough tracks for the other pins to have things happening on them, and make sure your mapping settings in the GUI are sending events for all the MIDI channels.

[DarianKimberly]

Is there a linux version or will I need to completely rewrite the code in a compatible format?

[Sammy1Am]

@DarianKimberly , Moppy's written in Java so you're good to go pretty much anywhere. In the bin directory there's a file named MoppyControlGUI that should (I haven't actually tested) allow you to easily run the ControlGUI. If that script doesn't work out of the box, it should only require minor adjustments, or you should be able to run MoppyControlGUI-2.0.1.jar directly as long as you set the classpath correctly.

[DarianKimberly]

Not sure how to set the classpath. New to this.

Did the script not work? What error are you seeing when you run it?

I'm happy to try to help answer specific questions; but because there are a ton of different variables to a given setup and Moppy generally just uses pretty standard libraries, you'll probably have just as much (or better) luck on Google for a lot of the generic getting-Java-working-on-my-system questions.

[DarianKimberly]

Just trying to figure out if I can control my arduino from my Raspbian setup as it is linux based. Not sure if it is compatible. the controller program is a windows batch file, and im not sure how to convert it into something linux friendly.

The reason behind this is that I want to make a portable version of the moppy built that i can control wirelessly through a raspberry pi zero w connected to my uno and VNC viewer.

So, just to clarify again, the controller program is a .jar file. There is a Windows .bat file included for running on Windows machines, and a shell script (the file I mentioned before in the bin directory) for running on Linux/Unix.

Try the shell script.

Edit: The setup you describe should work just fine, I'm fairly sure I've talked to others who setup Moppy similarly and it works great.

[DarianKimberly]

I tried and it just opens as a text file

Update. I manually set it to executable (for some reason this is not a default), and it opens for a brief moment, then just closes.

Try executing it from a terminal. It should output any errors in encounters (you can also look for *.log files in the Moppy directories).

If I had to guess though, it's probably a JAVA_HOME environment variable issue. Make sure that's set up correctly. (But try running from a terminal to look for the error first, it might be something else)

Edit: Actually, if you just scroll up on this page and read the thread you replied to, you can see that @JE521 had a similar issue and resolved it.

[DarianKimberly]

Again, no dice. I already tried executing it from the terminal.

What was the output when you tried to run it? (I can't help if I don't know what issues you're running into)

[DarianKimberly]

Executing in terminal results in a terminal that opens for a split second and immediately closes. Nothing else happens.

you could try the JAVA_HOME thing, just scroll up to beginning.

[JE521]

I think that the pin problem might be due to my use of an arduino mega 2560 instead of an uno. I will try to purchase an uno if there is no way to do this with my board. Also I will be less active on github because of school.

[DarianKimberly]

What do you mean by that?

@JE521 , The Arduino Mega should work fine for the first set of pins (roughly 2-19 or so). Can you maybe send a screenshot of your ControlGUI, just in case something with the mappers is preventing channels higher than 1 from being sent to the drives?

No rush of course, enjoy (?) school. ;P

[Sammy1Am]

@DarianKimberly . JE521 is referring to the original topic of this issue which he created.

Generally it's best to create a new issue if you're asking for help with an unrelated problem.

[DarianKimberly]

The problem is getting the GUI program to open. It just opens a command line for an instant, then immediately closes.

[JE521]

[JE521]

Also I have a driver board for my stepper.

[Sammy1Am]

Alright, so... this might seem like a silly suggestion, but I figure we should just make sure... The MIDI file you have open is called KirbysTheme (1 floppy).mid which I assume has been written for just one floppy drive (and therefore probably doesn't contain any notes for any of the other drives). Maybe try a different file?

As something to try though, you can click "Add Mapper" and set up the mappers like this:

n>22 && n<67	1	1	n
n>22 && n<67	1	2	n

That will basically take any note that comes in and assign it to SubAddress 1 (first row) and SubAddress 2 (second row). That'll make the first two floppy drives play the same notes, but could help testing your second drive.

Regarding the stepper motor, as long as the board is sufficiently similar to the L298N board, you should be able to comment out the two FloppyDrives lines in MoppyCore.cpp and uncomment the L298N lines. The L298N code was contributed by someone else so I don't know the nitty gritty, but if it doesn't work out of the box it should work with some small modifications.

[JE521]

That sounds like a good idea, but the 4,5 pins and so on don't work, I try restarting arduino on those pins and floppy wont play startup sound. Also the subaddress says play for 1 floppy because I set that when I saw the issue you forwarded me.

[JE521]

Also the 5.5" floppy doesn't work, so I am trying to tap into its stepper motor. And I am getting more 3.25" floppies soon.

[Sammy1Am]

• The startup sound only plays on the first drive. (You could change it in the Arduino code here if you wanted to)
• The MIDI file says "1 floppy" (try a different MIDI file!)
• You should be able to figure out how to get the 5.25" floppy working by manually grounding pins to see which ones control the stepping, &c. I guess it's possible the drive itself is dead and then you could just bypass it and control the motor directly.

[JE521]

I hooked up the right pins to the 2,3 pins on arduino. it wont move.

[JE521]

I am sorry i cut off this issue without notice, my computer broke and I was busy with school. I don't have the time for this kind of project. Thanks again for your help

Is fine. Education is important. I quit my job because they asked me if I valued education or my job more.
