You are right, the 132x32 match with the SSD1305 IC.

I inverted the screen and I counted the pixels. If I didn't miscount, it does seem to be a 128x32 display:

Well, in fact this a 128x32 screen, but with a shifted 132x32 buffer memory.

the screen selection name is now fixed !

Yes, looks like the SSD1305 IC has a native resolution of 132x32, so for 128x32 OLED screens it needs a 4 bit offset.

Thanks once again for your support.

Hello,

I think I have the same problem with my OLED displays. I'm still a beginner in this topic and have no idea how to get the firmware update on the board from the display. Can someone help me?

Cheers

I haven't really understood the problem yet. Is there a problem with the display and the firmware of the display is being adjusted or what is being adapted? I looking for a solution and ended up here, but I don't do anything with floppy emulators. I am building a cockpit for an F/A-18C and am using these displays. As I said, the problems are the same.

Cheers

There is two different controllers more or less compatible and the oled matrix can be wired differently. So some parameters need to be adjusted. Btw I have patched an Linux driver for another project to support SSD1306 & SH1106 screens :

Driver :

parameters :

Okay, thanks for the explanations, I'll give it a try when I get my hands on an OLED screen that could fit my needs.
