1.44 SPI inch TFT LCD

LCD Display Module

1.44 inch 128x128 SPI TFT LCD Panel
ST7735 Display Driver
Power Required 5VDC, 3V selectable.

My display does not show to correct pixel size. The size is set in the ST7735.h file, look for:

#define ST7735_TFTWIDTH 128
#define ST7735_TFTHEIGHT 128

Help, the colors are reversed in my bmp images!

Use tabcolor = INITR_BLACKTAB;

This will invoke the code snippet below whenever any pixels are written.

inline uint16_t swapcolor(uint16_t x) {

return (x << 11) | (x & 0x07E0) | (x >> 11);

}

Connection to UNO

1.8″ TFT – Arduino
LED - 3.3v
SCK - D13
SDA - D11
DC - D9
Rst - D8
CS - D10
GND - GND
VCC - 5v

remember to verify which pins things are connected to, these ones can change and should always be set by you.

#define TFT_CS 10
#define TFT_RST 8 // Or set to -1 and connect to Arduino RESET pin
#define TFT_DC 9

I will also mention, I just connect the pins to the Arduino, no worries about the logic level. If it were a concern just put a 4K7 in series.

From what I see on the net, we should just keep this between us. Don't want to set anyone off.
