Need help inserting script into Maestro Windows Controller

Support Servo controllers and servos
1

Hello,

I’d like to first make it known that I am by NO MEANS a programmer. A few years ago I bought some working “caution lights” for my racing simulator on my computer. The guy I got it from used these parts and software. The first time I used it, I cut and pasted the script directly into the script tab of the Maestro Windows Controller. I recently upgraded my Motherboard and CPU and have since now lost the functionality. I had to download and reinstall everything including the caution light software. When I tried to cut and paste into the script tab like last time, I either forgot to add/delete something or just plain not doing it right. I keep getting the following error - Subroutine call overflow/underflow

Can someone please examine the below file and reformat so it will work properly? Again, I’m not at all a coder so EVERYTHING in the script might as well be written in Chinese.

Thanks for any and all help and support!

Hello.

The “Subroutine call overflow/undeflow” error you are seeing in the Maestro Control Center indicates that the script has a return command without a corresponding subroutine call or the number of nested subroutines exceeds the call stack depth. For more details, see the description for Script call stack error (bit 7) under the “Errors” section of the Maestro’s user’s guide.

Considering that your script is quite lengthly, I do not think it is practical to ask someone to try to understand the code and fix the problem. I recommend contacting the person, who you got the script from, to help you fix the issue. If that is not an option, then I suggest you try simplifying the script to where it should work, but does not, or find the line in the script that is causing the error (by stepping through the script using the "Step Script " button in the “Script” tab of the Control Center).

Thank you for your reply! Unfortunately, I can’t get a hold of the guy who did it and what you mentioned, “the script has a return command without a corresponding subroutine call or the number of nested subroutines exceeds the call stack depth”, makes no sense to me. I read the description in the link you provided and again makes no sense. I don’t mind doing what needs to be done if the work of going through and finding the issue is too much for someone to do, however, what is it I’m looking for if I do the step by step function? An empty space, extra space after a return etc…? I have NO idea how any of this works unfortunately, so whatever you can provide in layman’s terms would be greatly appreciated. I did see that apparently I am maxing out of 126/126. Is that the number of rows in the script and that its too long?

Thanks again for your help.
Best Regards.

That is unfortunate.

The subroutine level counter you are seeing indicates the call stack depth (or the number of subroutine levels used) during the program’s execution; it does not indicate the minimum number of code lines (or rows) in a script.

I took another look at your script and noticed that it only consists of subroutines definitions with no main loop. I tested your code to confirm that the call stack underflow error occurs at the return command of sub greenout, where the program is trying to return to a point that is not defined. At the start of the script, the program just fell through into the greenout subroutine and immediately began executing it. One way to avoid getting the underflow error, you could define a BEGIN/REPEAT block at the start of your script. For example:

BEGIN
  greenout	# defined starting point, return here after executing subroutine
REPEAT

sub greenout
  #...rest of your script

Alternatively, if you do not want the program to repeat, you could use the QUIT command:

greenout	# defined starting point, return here after executing subroutine
QUIT		# stop the script

sub greenout
  #...rest of your script

Please note that implementing either of the examples above will get rid of the “Subroutine overflow/underflow” error, but it will probably not make your system work as it is intended. Again, you will probably need to contact the person you got the system from in order to get the product functioning as intended.
