Looking for advise on how to program the OLED on the UCTRONICS Pi Rack Pro for Raspberry Pi 4B to utilize the Pi-Hole information. The image above is an example.
The standard way has errors : No I2C device at address: 0x3c
The Blue background with white letters UCTRONICS is visible in the OLED
Yes I’ve enable the i2c & SPI
Still unable to probe for devise.

I ran i2cdetect -y 1
and got the following chart back:
I assume that would be ‘0x18’
I went to adafruit_ssd1306.py and modified the i2c address,
no errors but nothing changed on the oled screen.
The default 0x3c would have errors.

I tried the UCTRONICS in GitHub and was successful . I was trying to find an easier option. I don’t know C Language, I’m just learning Python. I have programed in Obj-C & Visual Basic. I convert the image into code.c using lcd image converter. not sure how to insert it into code.c.

No, nothing but frustrated over the i2c mismatch “ValueError: No I2C devise at address 0x3c”
