1.8 OLED


I created 10 identical devices with 1.8 OLED displays.

7 of them are working as expected... 3 of them have an erratic behaviour, interpreting commands in a funny way.

I posted two videos on youtube, one having the expected behaviour, one with the buggy display, source code is the same, running on an arduino compatible board in I2C.

OK : https://www.youtube.com/watch?v=lfQexr2uZyA

NOK : https://www.youtube.com/watch?v=OlXcnPpdTAU

If you have any idea...

Thanks for your help.



Can you see any difference on the module's PCB?

Compared your  2 videos, the "not working" one has different contents on the screen, what I saw on the bottom is: "Trsf:1" first, then "Trsf:-1", but the "good one" was different.
