Well, I can connect and download code, and do simple code. Blink the LED, use a breadboard with a temp sensor.
But nothing works for crap with display screens. Although, the last stackable board at least lights up.
I've tried LCD networked screens, all kinds of variations.......I am running Arduino Linux 1.8.19
I've split this question from your original topic as it does not sound like this relates to the cloud editor.
Please give a proper description of your problem, provide a list of hardware involved (with links to what you bought) as well as your code (and error messages if you get those) and a wiring diagram.
For informed help, please read and follow the directions in the "How to get the best out of this forum" post, linked at the head of every forum category.
That happens, post an annotated schematic showing exactly how you have interconnected everything. Show all power, grounds, power sources, external hardware etc with links to non generic Arduino device technical information.

Here is my code - note the 8347i is spec'd on the box for the screen, using 8347D.
Compiles and uploads ok, runs in the serial monitor - nothing on the screen.
