Hi, guys, and happy holidays to all of you,

I would like to create a switchboard whose potentiometers, rotary controls, and knobs change the values in a custom application.

I have no idea where to start. Any guidance would be very appreciated.

Thank you,

Val

sounds like a hardware problem and would only be related to Xojo if/when you had hardware that interfaced to your computer via a USB or other type port. No software solution can be devised without knowing your interface parameters.

Hi, Dave and Markus,

Thank you for your replies.

I need to clarify. I am trying to build a physical switchboard - something like a mixing board. Probably, I need to learn Raspberry Pi programming - how to read the status of the potentiometer and translate its value into a software parameter value.

I know that this could be done in Python, and I was wondering if XOJO could do it as well.

Thank you again,

Val

i think you need to read the analog values with gpip  
[documentation.xojo.com/topics/raspberry\_pi/gpio.html](http://documentation.xojo.com/topics/raspberry_pi/gpio.html)

the custom (xojo) application should also run at your raspberry pi?

its also possible to send data from Python via tpc socket into the network.
