(*1)
Serial.print of NUCLEO and DISC1 gose to PA2
If you use NUCLEO or DISC1, you need to change it.
(*2)
When a regulator(It's often AMS1117) is mounted on the back, it's operated 5V.
When a regulator is NOT mounted on the back, it's operated 3.3V.
Note:You can change to any pin. To change the pin, change Arduino-STM32-8bitTFT.h.
Note:Keep the wire length as short as possible.

NOTE
If you want to use a TFT that is not on the list, please let me know where to buy it with an issue.
However, expensive TFTs will not be supported.
This library uses LL GPIO Generic Driver.
Probably all boards that can use the LL GPIO Generic Driver are available.
Here is support status of low-layer drivers.

The default resolution of this library is 240x320.
If your TFT's resolution is 320x480,
you have to set your TFT's resolution using tft.setResoution.
ID = tft.readID();
tft.setResolution(320, 480); // Set your resolution
Serial.print("Device ID: 0x"); Serial.println(ID, HEX);
tft.begin(ID);
uint32_t width = tft.width();
Serial.print("Width: "); Serial.println(width); // You will see 320
uint32_t height = tft.height();
Serial.print("Height: "); Serial.println(height); // You will see 480
If your TFT's resolution is 240x400,
you have to set your TFT's resolution and TFT's offset.
ID = tft.readID();
tft.setResolution(240, 400); // Set your resolution
tft.setOffset(32); // Set your offset
Serial.print("Device ID: 0x"); Serial.println(ID, HEX);
tft.begin(ID);
uint32_t width = tft.width();
Serial.print("Width: "); Serial.println(width); // You will see 240
uint32_t height = tft.height();
Serial.print("Height: "); Serial.println(height); // You will see 400
