Power supply
To connect your power supply to the Tic, connect the negative or ground terminal of your power supply
to the Tic’s GND pin on the high current side of the board (next to motor output A1). Then, connect
your power supply’s positive terminal to the VIN pin next to that.
4.3. Configuring and testing the stepper motor
This section explains how to configure and test your motor over USB using the Tic Control Center
software. It is a good idea to test the motor over USB like this to make sure that the motor is working
and that you can get the desired performance out of it before you connect a different kind of input to
the Tic and try to use that to control the motor.
If you have changed any of the settings of your Tic, you should probably reset the
Tic to its default settings by opening the “Device” menu and selecting “Restore default
settings”. Then, go to the “Input and motor settings” tab and make sure the “Control
mode” is set to “Serial / I²C / USB” (the default).
The Tic’s motor settings can be found in the “Motor” box. This screenshot shows the default settings
for the Tic T825:
