How to covert an 16 bit signed integer value to a real voltage in an FPGA NIRIO 7833R

[zermelo]

Hello to everyone:

I have written a PID which is running on a NIRIO-7883R target, and I would want to know how to convert the integer values for the setpoint, the process variable and the feedback to real voltages. Which is the formula for this target?

Thanks,

Zermelo

Hello zermelo,

I think that you have the formules in the manual of the board. Is it correct you have NI RIO 7883R? Maybe is 7833. Anyway, in page 2-14 of 783x user manual, you have:

(AO

Voltage / 10.0 V )*32768
