Waveshare 1.28" Round LCD error

Using Arduino Displays

Can anyone throw light on what might be causing this error?

Round Waveshare 1.28" LCD connected to an Uno. Connections are correct according to several online sources (plus I connected it like this last time).

Just throws this error and I don't know why

The wiring is completely irrelevant at this point. The code won't even upload to the Arduino because it won't compile.

Did you test the display with one of the example sketches that comes with the library? It's always good to test like this before testing your own code.

The library github page suggests an example code called PDQgraphicstest.

If the example code won't compile, either something went wrong when you installed the library or there is a bug in the library.

The GC9A01.h library (which this screen uses) uploads..... but the screen doesn't work.
Tried a new second one... that doesn't work either

Its going to be one of 'those' projects

It's the UNO :roll_eyes:

Of all the things I didn't think it would be
