I am trying to create a datalog with my accelerometer values in RobotC.

When I ran the program, an error screen appeared reading:

Byte Code Interpreter Exception:
...
Exception Type: 'Real Adress Range Exception(59)'

The reason I find this confusing is that in the line of coded in question (marked by the arrow), I cast the long variable robotstate.lasttime into an integer.

Here is my code (the important bits):



Important notes:
robotstate.accelvals.x is an integer (yet no errors).
robotstate.lasttime is essentially nPgmTime(also a long)

I did change a line of code in RobotCIntrinsics: I commented out the initial delaration for AddToDatalog(); and uncommented another declaration to take integers as values:



Anyone know why I am receiving this error?

P.S Posted this earlier in another section, hopefully I get better luck here.

Your error seems to be an overflow one (the variable has overflowed into the adjacent memory slot). I think this is because longs are larger than ints, and therefore you can't cast longs to ints (it will compile, but at runtime the cast will fail). You can cast ints to longs though. The workaround would be to write your own casting function to handle this, something like:

The above code should work, but I haven't tested it. Get back to me if you're still around
Of course, you can change the limiting behavior to return 0 or whatever.
