I’ve got the LCD screen though the post, just in time. Rigged it up tonight, driving it from the RPi 3 using Windows IoT. Worked first time. I ported over my library from .NET Microframework, had to make some changes to accommodate the way the Win IoT stuff works, but happy that it was not too painful!
The display scrolls through a number of messages to the user while it waits for events.
I have a message queue that takes messages to display that other event handlers pump messages to.
Works as a pattern really well, thus why I’m reusing it for this project. You notice how slow the RPi is compared to the Netduino working with the display. It might however be setting I have wrong.
