Aeruino on labview

Hello,

i connected the MEGA 2560 to my computer, and the L LED is blinking, its ok?

second, when i trying to upload the code on the arduino software i have massege like this: “C:\Program Files (x86)\Arduino\libraries\RobotIRremote\src\IRremoteTools.cpp:5:16: error: ‘TKD2’ was not declared in this scope
int RECV_PIN = TKD2; // the pin the IR receiver is connected to”

i uses LIFA ( i dont know what that is…)

the code:
