(*1)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.
(*2)By several boards, This port is used as JTAG.
You need remap.

If your TFT's resolution is 320x480,
you have to set your TFT's resolution using tft.setResoution.
Example:
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.
Example:
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

If you want more faster, plase use this.
F4 board is very fast.

*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.
Copy JPEGS file to your SD-CARD.
*The biggest length of the JPEG file name is 32 character.
Wire TFT built-in SD-CARD Reader to STM32.
Execute JpegView_240x320_SMT32.
