Hey, i got a problem here, you see, i just got a new LCD screen and turns out it isnt working well, im pretty sure that it isnt hardware problems since when i press the RESET button on my arduino UNO, it shows the images just fine, when i release or dont press it at all, it shows this image all buggy, i really dont know what to do, i did the pinout just as the code said, here it is btw:
// ST7789 library example

/*
ST7789 240x240 IPS (without CS pin) connections (only 6 wires required):
#01 GND -> GND
#02 VCC -> VCC (3.3V only!)
#03 SCL -> D13/SCK
#04 SDA -> D11/MOSI
#05 RES -> D8 or any digital
#06 DC -> D7 or any digital
#07 BLK -> NC

//#define TFT_CS 6

#define SCR_WD 240
#define SCR_HT 240 // 320 - to allow access to full 240x320 frame buffer

Arduino_ST7789 lcd = Arduino_ST7789(TFT_DC, TFT_RST);
//Arduino_ST7789 lcd = Arduino_ST7789(TFT_DC, TFT_RST, TFT_CS);
void setup(void)
{
Serial.begin(9600);
lcd.init(SCR_WD, SCR_HT);
lcd.fillScreen(BLACK);
lcd.setCursor(0, 0);
lcd.setTextColor(WHITE,BLACK);
lcd.setTextSize(3);
lcd.println("HELLO WORLD");
}
void loop()
{
}
Any tip is welcome, thx in advance.
