Hi I am trying to match up the way a motor works under NXT mindstorm brick to NXShield on Arduino using the exact same configuration. But the motor behaves quite differently for the following setup.

angle = 8 degrees
power = 100
use power control = true/checked
Action = Constant
Next action = Brake

When I translate these settings over to NXSheild I use the following

nxshield.bank_a.motorRunDegrees( motor, direction,
100,
8,
SH_Completion_Wait_For,
SH_Next_Action_Brake);

But they behave very differently even with an external 9v power supply on NXShield.

When I run with lego brick, the motor would move very sharply and oscillate to rest (that'st he behavior I actually want). But in NXShield, the motor moves a little bit but not as sharply as the brick and doesn't oscillate. Then I tried to run the motor by putting 0xBD into the registerA of motor 1 but still no to avail.

Does anyone know how to get NXShield to work exactly like the brick under the above settings. Thanks

Would you be able to post your full code using the [code] tags? Also, is this code being written in ROBOTC or Processing? I ask because the sample programs on the NXShield's site are using Processing.
