For those that are interested in LCD support, I did start to enable it natively within OSPI. It look some time to figure out the various components in the OS code, but I was able to pretty much get it all working without adding much code at all. If there is interest, I can issue a separate pull request for LCD support for the RPI. I’m still figuring out what other stuff I want to display on it and I’ve not put the options in the menu yet to enable/disable it and change the config.
I’ve also been working to enable MQTT support as well: MQTT Integration
What I used was a i2c connected 20×4 LCD. I snapped a couple pictures if you are curious what it looks like. I did have to modify the circuit a bit since they are really made for both 5v logic and 5v lcd.
