I have been using this display for two years for my project. I have a problem in summer time when it heats up from the sun above 50 degrees celsius. The display turns white and nothing can be seen. When it cools down in the shade it works again. Could you please advise me what I can do in this case. Have you had this problem? I buy the displays from AliExpress.

Hi, Everything works as you say but in my case the display is mirrored. Any known fix for that? Thank you!

Try this configuration, it might work: If your TFT has this pins: Vcc - 5v Gnd - Ground Gnd - Ground Ncc - Ncc - Ncc - CLK - pin 13 SDA - pin 11 RS - pin 9 RST - pin 8 CS - pin10 Install adafruit GSX and adafruit ST3375 libraries (I'm not sure about filenames but in my case my filename ends with "-master") Do not use any of libraries example sketch. I write my own code from scratch Do not include these libraries in the code. just "Include " and "Include SPI.h" Here's the link I learned the code from www.arduino.cc/en/Guide/TFT Also, weird thing happens.When i use rgb function like ".stroke(red,green,blue)", color is reversed. So it's not RGB. It's BGR. (blue,green,red) I think my TFT is just cheap cloning. It's like buying TV with unknown name and there's no manual in the box. My code: /* TFT Pin - Arduino Uno & Nano*************** Vcc - 5v Gnd - Ground NCC - NCC - NCC - CLK - 13 SDA - 11 RS - 9 RST - 8 CS - 10 ************************************************** */ #include // Arduino LCD library #include // pin definition for the Uno #define cs 10 #define dc 9 #define rst 8 // pin definition for the Leonardo // #define cs 7 // #define dc 0 // #define rst 1 // create an instance of the library TFT TFTscreen = TFT(cs, dc, rst); void setup() { TFTscreen.begin(); TFTscreen.background(0, 0, 0); // clear the screen with a black background // (0,0,0)- Black (255,255,255) - White TFTscreen.stroke(255,0,0 ); // stroke(blue,green,red) TFTscreen.text("Line Square Circle",20,8); TFTscreen.stroke(255,255,255); TFTscreen.line(0,20,160,20); TFTscreen.stroke(255,255,255); TFTscreen.line(0,120,160,120); TFTscreen.fill(255,0,0); //Square with fill color TFTscreen.rect(20,30,30,30); TFTscreen.fill(0,0,255); //Circle with fill color TFTscreen.circle(80,45,15); /* TFTscreen.line(120,30,105,60); //Triangle with fillTriangle TFTscreen.line(120,30,135,60); TFTscreen.line(105,60,135,60); */ TFTscreen.fillTriangle(120, 30, 105,60,135,60, ST7735_GREEN); //(x1,y1,x2,y2,x3,y3,ColorName) } void loop() { }
