The ROBOTC Debugger Timers
The Timers debug window provides access to current values of the timers built-in to your 
microcontroller. On the VEX Cortex, there are 4 user-accessible timers (T1, T2, T3, and T4), 
and two system timers (nSysTime and nPgrmTime). The 4 user-accessible timers can be 
modied in real-time using the Timers debug window, but the two system timers cannot.
Reference
Index
The index of the timer (T1-T4).
Timer
Name of the timer. “nSysTime” is the amount of time the controller has been powered on. 
“nPgmTime” is the amount of time the current program has run. Timer1 through Timer4 
can be reset and monitored in your programs. 
Time
Displays the elapsed time. 
The Timers window can be opened by going to the Robot menu, Debug Windows, and 
selecting Timers.
