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 feel the pain 
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.
Why on earth do you post an unreadable picture of text?
Did you try the addon in the thread I pointed you to?
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.
Look I know you are new here, but I was asking if you had tried the addon mentioned in this specific post
No I have not, I will look into it, thank you
No, nothing but frustrated over the i2c mismatch “ValueError: No I2C devise at address 0x3c”
Then post on the author’s github.
They are writing to 0x00 and 0x01
