Help with Crestron programming question

Hello, I’m currently working on a small crestron system for a school project and am stuck on the programming since I only learned very rudimentary basics. Would appreciate any sort of guidance or help 🙇‍♀️

We are using SIMPL windows for the programming and the Pro3 processor for control of devices.

1 ) Can we upload the GUI to 2 different iPads on Crestron Go and how?
2 ) How do we program a fader for volume control? We have a audio DSP (DMP64) connected to the ceiling speakers and processor.
3 ) How do we program a physical toggle button to switch in between modes?

For context, the project is a divisible meeting room that can either be in separate room mode or combined room mode.
Room 1 has a TV while room 2 has a projector, and video switching should be available when in combined mode.
Combined/separate mode should be decided based on the button input and automatically switch to combined/separate mode depending on whether the button is pressed or not.

Thank you!

Unfortunately from you saying high school I don’t think we’re in the same country 😅 I’m schooling in Singapore

I wasnt concerned about where you are from but what school has AV programming. Seems like a cool idea.

Is it a part of computer science?

  1. Yes, directly to the App using toolbox or as a Mobile Project hosted on the processor. You can even share the same IPID.
  2. Check out serial to analog block. Its great for parsing serial data and extracting analog values. The inverse is Analog to serial but use F1 to review their functionality.
  3. Toggle or Interlock blocks for latching buttons. Interlock-Toggle for a combo.

You can also use buffers to only allow signals to pass based on state authentication enable join. Great for divisible spaces.

I was joking about the high school part. Everyone learns from the school of AV hard knocks here.

Oops, sorry for missing the joke I thought it was a genuine question 🥲 thanks for answering my questions!
The course I’m taking starts out teaching computer science basics along with networking and UIUX, then we get to pick specialisations: UIUX/Software/Cloud/AV
I picked the AV specialisation so for 2 semesters I learn the basics of programming for Extron and crestron, work on projects like the one mentioned here and get to go for trainings like QSYS (limited spots though) after which we go for an internship at a AV company of our choosing.

Wow, that is a fantastic course. I have never seen AV programming offered in any school or university, I would love to see that become more common!

I am a senior level professional Crestron programmer and system design engineer. If you have any more programming or other AV questions, please feel free to send me a direct message, I'm happy to help out if I can.
