MATRIX Using Motor Servo Controller
The MATRIX Controller
|The MATRIX Controller is very similar in operation to the HiTechnic Controllers used in the TETRIX system, but there are some key differences between the two. The biggest difference is that the MATRIX Controller cannot be daisy chained to other controllers as the HiTechnic Controllers can. As a result, the MATRIX controller is a combination motor/servo controller. It can handle up to four DC motors and four servos at one time.
Because the MATRIX Controller cannot be daisy-chained , setting up ROBOTC for a MATRIX controller is a fairly easy process. Simply open the Motors and Sensors Setup window under the Robot menu in ROBOTC, navigate to the External Controllers tab, and select "Standard MATRIX Configuration". This will designate Sensor Port 1 on the NXT as the port that the MATRIX Controller is attached to. There are a total of four settings in the External Controllers tab to chose from:
When the MATRIX Controller is selected in the External Controller tab, ROBOTC will automatically update the Motors, Servos, and Sensors tab with the respective changes. It will add the four supported motors in the Motors tab (Motors D, E, F, and G).
