I wrote this code which has no build, link, or compile errors, but has the error memory permission error 03802600 when running the code on the robot, not when downloading. Any suggestions?
this is all in V5 pro.
This is the code from the main.cpp file.

edit by mods to add code tags.
Don’t do this.
It’s meaningless, only access Controller1 inside a function.

I got rid of it and it still had the same problem.
Expanding on this, don’t calibrate inside the loop, as well.
You’ll want to read the value from the joystick each time thru the loop, as written, even if you didn’t get a memory error, the value of leftmod and rightmod would always be zero

I removed the segment completely, and still had the same problem. Should I post other the Header files?
about two years ago I had the problem that if I don’t assign initial values to variables, the memory permission error message would appear
try initializing all of them to zero

did this, did not solve the problem, but good suggestion.
In general, when the source of error is unclear, you may want to start with an empty competition template and add one construct at a time, verifying that everything still runs fine after each step.
Also, I don’t see you calling vexcodeInit() from pre_auton() function as it is shown in the linked kb.vex.com article.
