Looking to connect the Pi zero W with a 7" touchscreen with a MMDVM hat.

First off, is this possible? Can I connect a pi zero W to use as a screen instead of the standard OLED3.
Second is that I have it is a FLIRC case for Pi zero so maybe output via the HDMI and micro USB for the touchscreen might work.
lastly,
Can this be done with some code and a workaround. Something to show the connection, call in and where it is connected to type of thing.

Has this been done and if so, how.

If your hotspot has an oled display its prob. based on a pi zero. If so that board doesnt have the processing power to run a GUI to drive a HDMI screen if your intent is to have the pistar dash open and displayed on it.

If you need a bigger screen, look at using a nextion screen with ur hotspot. They range upto 10" and its use wontimpact that much on the Pi.

I have, successfully, tested using my MMDVM, Pi Zero W, and Nextion 7” screen.
The biggest issue I faced, was finding a Nextion image, for the screen, as most popular sizes are 2.4, 2.8, and 3.5 inch screens.
I have not, (so far), noticed any major issues. My only change, will be to power the screen separately, as it does ‘flicker’ a little. My 2.4” screen is fine being powered from the hotspot.
