Controlling the digital outputs
The USB DrDAQ device includes several digital connections. To activate the digital
outputs, ensure your accessory is connected both to the
GND
of the USB DrDAQ and
the digital connection you wish to control. To operate the connections click the digital
output icon above the oscilloscope window. The following drop down will appear:
Moving any of the 4 sliders to
High
will activate that digital output. Only outputs 1 and
2 are able to output a PWM (Pulse Width Modulation) signal. To do this click the
Digital Out icon above the oscilloscope window and choose PWM in the drop-down for
either digital output 1 or 2.
This allows adjustment of the
PWM Period
and
Duty Cycle
values.
Examples of digital in/out use
