white line at edge of display

[PaulVdBo]

• Arduino ide 1.8.19
• TFT eSPI 2.3.4
• display ST7735_GREENTAB 160x128

define ST7735_DRIVER

define ST7735_GREENTAB

define TFT_HEIGHT 128

define TFT_HEIGHT 160

define SPI_FREQUENCY 40000000

3.3V for display comes from ESP32 board. (measured : 3.2V) 3.3V for LEDs comes from motion sensor via "amplifier" (measured 3.0V)

sketch : TFT_CLOCK

void setup(void) { tft.init(); tft.setRotation(1); tft.fillScreen(TFT_BLACK);

compiling = OK. sketch runs fine.

BUT... :)

I have a random colored line at left side of display (I guess 2 pixels wide) as well a few colored pixels at the top row. I tried GREENTAB, GREENTAB2 and GREENTAB3 : all same "problem"...

What am I doing wrong ?

I'm sorry if this problem has been mentioned somewhere else. In that case : just send me there :)

Mega thanks in advance !

I connected the display as follows :

MOSI - > 23 CLK -> 18 CS -> 15 DC -> 2 (named A0 on the display) RST -> 4

Try the other board types. My "greentab" is actually a "blacktab"
