AXE134Y OLED 20x4 - problem

[kolber]

I have AXE134Y OLED 20x4. 16 - ti pin connector I'm first connect badly (inclusive pin 15 plus 16). Then I'm connection repaired. After go on will make light this. On nothing responds.
Software is OK. What about it?

Are you interfacing the AXE132 with the correct baud rate and polarity?

Also make sure the connection is actually repaired - I've noticed that a similar thing happens if the Register Select line is held low.

Yes, i have correct AXE132.

 

[nick12ab]

What code is programmed on to the AXE132?

If we understand correctly, you initially soldered the connector incorrectly (all pins offset by 2 to what they should be).
In that case if you powered up the board there is a high chance that the OLED has been damaged, as power would have been incorrectly applied to the OLED pins.

Yes, either it I think, that the is oled harmed. Already I'm ordered new.
