IME - Byte code interpreter exception from ROBOTC forum

[jpearman]

For some reason, whenever I call “nMotorEncoder” on any IME, I get a ROBOTC Exception Violation Report saying

“Byte Code Interpreter Exception:
Program Slot: 0, Task ID: usercontrol[2]
Error at PC: Teleop+0x0021
Task at PC: Teleop+0x0021
TaskState: ‘Exception’
Exception Type: ‘Invalid Sensor Encoder Port for Motor(64)’”

I verified that everything was set up properly in “Motor and Sensors Setup,” but I still get this error. Here is a copy of my pragma code at the start of our program:

We really need these IMEs to work… HELP PLEASE?!

I can’t post in the ROBOTC forum, so, here is the answer.

You need to use the motor port as the index to nMotorEncoder

use nMotorEncoder LeftMotor1 ] or nMotorEncoder port2 ].

Do not use the sensor name ie. do not use nMotorEncoder I2C_1 ]
