I am stuck with a problem.
I have a task whereby I am supplying 6V to a pressure sensor. This is supplied inside a while loop using a constant value of 6 -- "one sample on demand."
At the same time I have to supply pulse width modulated (PWM) voltage to a pressure release valve. This valve is CLOSES (ON) on 4V and OPENS (OFF) at 0V. I kind of want to flap this valve (OPEN-CLOSE) at a certain rate to achieve a specified leakage in the the system.
I used another channel of my DAQ Book and gave it simulated square wave. However, this requires the DAQ to be set at "continuous samples." So, there is a conflict.
I tried to supply my 6V to the pressure sensor using "continuous samples" but it failed. Also, I tried to configure the DAQ for simulated signal as "one sample on demand." Again it failed!
Please see the VI attached.
Is there a simple and consistent way to send the desired voltages to both devices?
Thanks a lot!
