First off. Make sure that you have a recent Arduino IDE. The current version is 1.8.5. I am using v1.8.1.
Update your MCUFRIEND_kbv library with the IDE Library Manager. Current Release is v2.9.7
You appear to have an HX8347-D controller.
Edit MCUFRIEND_kbv.cpp to enable SUPPORT_8347D
Then run the graphictest_kbv example.
On my Uno (with a Beta library) I get:
Sketch uses 30782 bytes (95%) of program storage space. Maximum is 32256 bytes.
Global variables use 1591 bytes (77%) of dynamic memory, leaving 457 bytes for local variables. Maximum is 2048 bytes.
Older Arduino IDE versions might use more Flash memory.
I would expect your Uno to be able to run ALL of my examples 100% without any edits.
Please take notes about your directions. In the "penguin" screens, note which ones have mirrored text.
David.
