Unable to select display I2C adress in web configurator #166

Closed basst22778 closed 2 years ago

i am trying to chance the i2c adress in the web configurator as discribed in your comment. https://github.com/shanteacontrols/OpenDeck/issues/28#issuecomment-633228800

There is no option in the interface. (bluepill, V7.3.2) Is this option already depricated?

Can you post a screenshot?

Ah, right. The option has been removed because the code tries to automatically determine the address of the display. Right now the two probed addresses are 0x3C and 0x3D.

basst22778 commented 2 years ago

the specs say 0x78 - according to this article https://community.element14.com/members-area/personalblogs/b/blog/posts/oled-i2c-silkscreens-are-wrong-or-are-they it should work.

Maybe the display is broken. Another display from a different manufacturer works fine.

0x78 is actually 0x3C and should work fine, however, I have run into some displays from eBay that simply do not work at all.
