Program FPGA myrio

[NiktuStark]

Hello!,

I'm working on programing (for now) some servo control for opening and closing some valves for a real plant in a myRIO 1900 hardware.

My trouble is about scaling the inputs and outputs on the FPGA. I have a FPGA.VI implemented where I define the PWM, but when I execute it I don't have any voltage signal (mesuring with the multimeter) and I think this error is correlated with the scaling raw values to voltage.

Can someone give me an idea how to scale it?  I tried using a property node with the Analog Output Value to work with the LSB value, but Labview does not accept it.

Thanks in advance,

Carlos

Hi NiktuStark,

Here you have an explanation of how to scale analog I/O in FPGA:

Why is My Analog Input Reading Off By a Factor of 10 on My FPGA R Series RIO?

Hope it helps.

If you could program it in RT, take a look of Data Dashboard for myRIO.lvproj, you find it here:

Have a nice day!
