The firmware doesn’t support this type of OLED yet. It does support I2C 1602 LCD (this is the same type as the fully assembled OS 2.3 / 2.3 DC uses), so it would be relatively easy to modify the firmware to extend the support to OSPi.
Could you please point me in the right direction? I really need to get this going, I found some documents and modifications to your code on github and I got the right lcd and i2c adapter delivered today, I just dont know how to put everything together as an image or if I can just find the files and replace them. It is the work done by denisfrench.
