Hi everyone,
I am trying to get a round tft display working on my R4 wifi i am getting al kinds of errors.
so for my code i am using the example code for the Adafruit_GC9A01A called graphics test.
#include "SPI.h"
#include "Adafruit_GFX.h"
#include "Adafruit_GC9A01A.h"
// Define pins for display interface. You'll probably need to edit this for
// your own needs:
#if defined(ARDUINO_SEEED_XIAO_RP2040)
// Pinout when using Seed Round Display for XIAO in combination with
// Seeed XIAO RP2040. Other (non-RP2040) XIAO boards, any Adafruit Qt Py
// boards, and other GC9A01A display breakouts will require different pins.
#define TFT_CS D1 // Chip select
#define TFT_DC D3 // Data/command
#define TFT_BL D6 // Backlight control
#else // ALL OTHER BOARDS - EDIT AS NEEDED
// Other RP2040-based boards might not have "D" pin defines as shown above
// and will use GPIO bit numbers. On non-RP2040 boards, you can usually use
// pin numbers silkscreened on the board.
#define TFT_DC 9
#define TFT_CS 10
// If display breakout has a backlight control pin, that can be defined here
// as TFT_BL. On some breakouts it's not needed, backlight is always on.
#endif
// Display constructor for primary hardware SPI connection -- the specific
// pins used for writing to the display are unique to each board and are not
// negotiable. "Soft" SPI (using any pins) is an option but performance is
// reduced; it's rarely used, see header file for syntax if needed.

but this keeps giving me an error:

What can i do to fix this for the R4
