cannot initialize device

[homonto]

hi there,
I just connected this display and I am trying to use your library
unfortunately there is an issue
my display is 7 pin from Aliexpres
I connected as following:
VCC, GND
SCL= GPIO 11, PIN 23
SDA=GPIO 10, PIN 19
RESET=GPIO 27, PIN 13
DC=GPIO 25, PIN 22
LED(BACKLIGHT)=GPIO 24, PIN 18

same as in your example: clock_EN.py:
RST = 27
DC = 25
LED = 24

when running the example script always the same error:

$ python3 clock_EN.py Traceback (most recent call last): File "clock_EN.py", line 36, in <module> disp = TFT.ST7789(spi=SPI.SpiDev(SPI_PORT, SPI_DEVICE, max_speed_hz=SPI_SPEED_HZ), File "/usr/local/lib/python3.7/dist-packages/Adafruit_GPIO-1.0.4-py3.7.egg/Adafruit_GPIO/SPI.py", line 46, in __init__ SystemError: error return without exception set

I am not sure how to make it working
the power is there (I can see some backlight on) but nothing else
any help would be appreciated

thx
