Using This screen from other issue . With the ESP32-S3-DevKitC-1-N-8R2 I have the LCD working, but I can not make a sprite that is full screen. No matter what size sprite I make, it will cap out at around 60% of the 320x480 pixel screen via SPI interface. I do not have the touch chip or SD card wired up, just the LCD pins. I can see the PSRAM enabled, and have the sprite.setAttribute(PSRAM_ENABLE, true);

I CAN see the entire screen when running a demo example with non sprite pushes, but the library seems to be force capping the size of my sprites, EVEN with PSRAM enabled. What am I doing wrong?!

Solved my own issue. I guess I don't quite understand why, but when I set rotation to 1 for landscape, the Height and Width dimensions are now flipped for sprite creation. It's strange, I have to pretend it's oriented portrait when using pushSprite and create sprite. Is that supposed to be that confusing? Why not flip them when you set rotation for consistency?

Hmmm.. I thought for sure you would not be able to use gpio 35,36,37 when PSRAM is activated. I see that you are using these lines for MISO, MOSI, SCK and it works. Can you please verify that is the case. That opens additional possibilities for me! Thanks

The ones with QUAD type don't use those pins, but the OCTAL ones do, I think those models have 16mB flash and/or larger PSRAM. I went a model down to avoid loss of those pins, so can confirm they still work.
