Grant, does the device work when you use test-usb1208FS-Plus? Use the 'i' option to read from different channels. If it works, use this code as a template for your own code. If not, please send me screen shots of what you see using test-usb1208FS-Plus.
Hi Warren,
I have now made this work. My problem was that I was not bridging the AGND of the 1208FS-PLUS to the CH LO of the analogue input. This is specified on page 11 of the user manual.
I am having a new issue however where it will read around 0.2VDC greater than the actual VDC going into the channel.
Thanks, Grant
It is possible that your ADCs are out of calibration and you have a bias. You might need to calibrate your device (contact MCC) or add a bias when you do your calibration.
A call to the following function with
actuatorPos(0,0);
and
actuatorPos(1,0);
return the same value despite each input having a different voltage
