OLED Update timing problem

<< < (3/3)

Saurabh_B:
I am still unsure how you are getting characters to show up when the display is powered on.
All of our OLED displays do not show any information until they have been given data to show.

Would it be possible to show me a picture of what characters you are seeing, also a video describing the problem.

I believe the DDRAM of the OLED display is being updated when the power is not appled.

One simple solution is to use the display OFF command after the display boots up from a reset / power off. After this i would recommend doing a clear display before using the display ON command.
