commands when these modes are enabled could provide unexpected results. In particular, don't combine the
following:
● DOUT functions while in Motor Controller mode
● DAC functions while in Function Generator mode
● Using ADC functions while in Oscilloscope mode
Motor Controller
With a current handling capability of 3 amps per channel and a maximum voltage of 30 volts, the eight DOUT
drivers make an ideal, dual unipolar stepper motor controller. When used in this mode, the pinout mapping
changes to:
It is beyond the scope of this document to explain the theory operation of unipolar stepper motors so we
suggest you learn more about them
here .
Connections
The picture below shows how to connect two 12VDC stepper motors to the DOUT header. In this case, an
external supply is used and is attached to the ground connection on terminal block TB2 - pin9 and to the
flyback protection pin. The power connections for each of the motors also attach to the flyback terminal.
