Problem from Learning ArduPilot — The Example Sketches

[ngocth...@gmail.com]

I am beginner to use Pixhawk, 

i start with some example:

• libraries/AP_GPS/examples/GPS_AUTO_test
• libraries/AP_InertialSensor/examples/INS_generic
• libraries/AP_Compass/examples/AP_Compass_test
• libraries/AP_Baro/examples/BARO_generic
• libraries/AP_AHRS/examples/AHRS_Test

But:

when i download these example, only: GPS_AUTO_test, work. Others (INS_generic, AP_Compass_test, BARO_generic,AHRS_Test), i can not see any thing in the Terminal.

let help me.

Thanks
