(*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.

Setting your TFT's resolution
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

F4 board support
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.
How to use
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.
