Is it possible to run this 1.54 TFT-SPI-ST7789 display with Wemos D1 mini v4.0 ?
I have tried different wiring and different libraries to make it work, but no success.
For example
Wemos - TFT
3.3V - VCC
GND - GND
5 - SCL
4 - SDA
16 - RST
0 - DC
15 - CS
Libraries
Adafruit_ST7789
Arduino_ST7789
TFT_eSPI
Can anyone help?

I've also tried this Display with Arduino Nano, but no luck.
So I think I following wrong tutorials and don't undestand the concept.

I have figure it out. I know that I am beginner in this area so sorry for the topic.
In case of somebody has similar problem I write down my findings.
Wiring:
WeMod D1 mini V4.0 - 1.54 TFT SPI ST7789
3V3 - VCC
GND - GND
14(SCK) - SCL
13(MOSI) - SDA
2 - RST
4(SDA) - DC
15 - CS
3V3 - BL
In code:
// Adafruit_GFX.h
// Adafruit_ST7789.h
#define TFT_CS 15
#define TFT_DC 4
#define TFT_RST 2
Adafruit_ST7789 tft = Adafruit_ST7789(TFT_CS, TFT_DC, TFT_RST);
...
tft.init(240, 240);
...
