I'm new to xojo & have never touched a Pi, however I'd appreciate any upfront thoughts on the following:
It's always a challenge writing a decent, graphical GUI for an embedded system. The GUI can take longer to develop than the actual instrumentation.
Small tft displays with some kind of 3rd party graphics library is the normal route, but it's always a real chore.
Ideally, the GUI would be a tiny PC or Pi-like system, making the GUI much easier to develop.
How viable is a Pi option to act purely as a display, do you think?
As a basic example, let's say we dedigned an instrument to measure temperature, but we wanted a cool GUI to go with it.
Typically you'd be able to display, chart & log the temperature, so the display would have a live chart, large fonts for the readings & a few different setup windows/pages.
The Pi would need to boot fairly quickly. No-one wants to power up an instrument & wait 5 minutes for the thing to boot!
It would also need to be illusive & not show that It's a Pi! We don't want a bunch of booting text showing on the display as it fires up.
I'm wondering if I could create such a system with Xojo & a Pi.
Any thoughts appreciated.
