Unknown Unhandeled Exception

abracadabra

I have interfaced the javalin stamp with a vector compass and whenever I run the code for a few seconds...I get unknown unhandled exception...

Can someone please help

Peter Verkaik

[noparse][[/noparse] Error IDE-0042] Unknown unhandled exception in JVM (924).
[noparse][[/noparse] Error IDE-0015] Stack trace is corrupt.
[noparse][[/noparse] Error IDE-0024] Unknown bytecode in the JEM file (dup_x2).
Thanks!
If you need my code, let me know and i will gladly post it.

Peter Verkaik

Yes, post that code. Some unhandled exceptions appear to

origin from a static definition but without code I can't tell.

Also, stack trace error: do you use recursive programming (although

that should lead to Out of memory if the recursion never stops).

Can you trace the origin of the error by commenting out the most

recent additions to your code?

So was there any outcome to the above?

I have been tinkering away for the last week prototyping and now am getting similar messages with these two lines...
System.out.print("Extracted var1=");
System.out.println(var1.toString());

where var1 is "static StringBuffer var1 = new StringBuffer(80);"

Messages are...
IDE-0028 Unhandled exception in JVM
IDE-0015 Stack trace is corrupt
IDE-0024 Unknown bytecode in JEM dups_x2

No recursion, 18000 bytes free, nothing reaching their limits.

Since they are debug statements, I have removed them and the problem has gone away.

I used to get all sorts of spurious problems, when I tried to run two Javelins on a single, small power supply. I upgraded to a switching power supply providing over an amp, and all the problems stopped. I recommend supplying more current and seeing if life gets better.

Javalin

Also worth checking that anything connected to the IO pins is not drawing tooo much current. Can cause odd issues!!
