@nruffilo , I suggest you make the following changes to the Setup47_ST7735.h file, which is inside the UserSetups folder. Or create a copy of this file, naming Setup##_Rp2040_ST7735.h, for example. Then, make a reference for this file in User_Setup_Select.h, creating a line with #include <UserSetups/Setup##_Rp2040_ST7735.h>

See if it works.
This worked! You are amazing. Thank you so much! I did have to swap to RGB and not BRG but that was an easy find/fix.
Perfect!
Did you change this line?
//#define TFT_RGB_ORDER TFT_RGB // Colour order Red-Green-Blue <- Uncomment this
#define TFT_RGB_ORDER TFT_BGR // Colour order Blue-Green-Red <- Comment this
Good!
Yes, the display I have is RGB

@djairjr Thanks for helping resolve this.
I'm using a pi pico with the https://www.adafruit.com/product/2088 breakout board. I can confirm the wiring works with the standard adafruit_gfx library graphicstest, and used the same configuration with TFT_eSPI and was unable to get any of the examples working.
I tried all of the following:
define ST7735_DRIVER
// #define ST7735_INITB //#define ST7735_GREENTAB //#define ST7735_GREENTAB2 //#define ST7735_GREENTAB3
define ST7735_GREENTAB128 // For 128 x 128 display
Ideally I'd love to get the animated eyes working - and your DMA rewrite (as opposed to the original zeroDMA implementation) is extremely exciting. Any tips you might have would be greatly appreciated, or if you can let me know what code in your library may be the issue I can attempt to find/solve it myself and contribute back. Thank you!
BTW - code compiles and uploads, but screen remains white.
