Arduino Nano RP2040 Connect + ILI9341 SPI TFT, using adafruit_ILI9341 library.

To drive ILI9341 SPI TFT on Arduino Nano RP2040 Connect (Arduino framework), Adafruit_ILI9341 library can be used.

Install Library:

In Arduino IDE, open Library Manager, search and install Adafruit ILI9341, Adafruit GFX library is needed also.

You will be asked to install extra libraries needed, click Install All.

Connection:

Connection:
ILI9341 TFT	Nano RP2040 Connect
-------------------------------
VCC		3V3
GND		GND
CS		D10
RESET		RESET
DC		D9
SDI(MOSI)	D11 (SPI0 TX)
SCK		D13 (SPI0 SCK)
LED		3V3
SDA(MISO)	D12 (SPI0 RX)

After then, you can try Adafruit_ILI9341 example graphicstest.
