DSP Robotics Support

I have Phidget Interface Kit,voltage and current sensors. voltage sensor is nonratiometric and current sensor is ratiometric. In phidgets API you can enable or disable ratiometric option but I didnt see this ability in Flowstone or I dont know. Do u know how could I enable or disable ratiometric option for InterfaceKit through Flowstone.

Thanks

Hi Pars,
I assume you are using one of the sensors that connects to the regular phidgets interfaces. Which model exactly are you using? I noticed on the Phidgets support pages (for example this one), that they have equations there for transforming raw sensor values into actual voltage and current values. My guess is that the 'ratiometric' setting in the API is applying exactly these equations - so it should be possible to build a small maths module to take the values from the Phidgets primitives in FS and do the same transformation.

I am using PhidgetInterfaceKit 8/8/8. Unfortunately that method is not working because sensor digital value is changing according to ratiometric and nonratiometric option. I did try calibration and if I choose nonratiometric option when I was calibrating it, It is impossible to calibrate it, it is giving different value every time. Same thing happens for ratiometric option chosen for non-ratiometric devices.
This is how we calibrate sensors http://w3.tue.nl/fileadmin/id/objects/E ... ensors.pdf

In the Phidgets website,it shows that getratiometric and setratiometric APIs but I dont know how can I apply it to Flowstone
