1.44" ST7735 TFT LCD Display

Hello everyone,

I have some trouble with getting this cheap tft display to work.


As you can see on the back, I should use a ST7735 driver ic so I tried Adafruits library but with no success.
It’s correctly wired.

This is “my” code:

#include <Adafruit_GFX.h>
#include "Adafruit_ST7735.h"
#include <SPI.h>

#define TFT_POWER 13
#define TFT_SCLK  12
#define TFT_MOSI  11
#define TFT_RST   10
#define TFT_CS    9
#define TFT_DC    8


Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_MOSI, TFT_SCLK, TFT_RST);

void setup() {
  digitalWrite(TFT_POWER, HIGH);
  
  tft.initR(INITR_BLACKTAB);
  tft.fillScreen(ST7735_BLACK);  
}

void loop() {
  
}

After toying arround and adding SCLK / MOSI:

ANOTHER EDIT!
I am super stupid…
I switched DC and CS. FML.

Any Ideas?

Kind regards
