Hi,
I'm using a Groove OLed display SSD1308, 128x64.
My designs from the past do work perfectly with this display but recently with modifying the design the display clear function does not clear the full display.
The first 2 pixels of every line are not cleared except for a few pixels..
Please check..

Re: GLCD (SSD1308) Clear function does not fully clear
A couple of quick questions:
Is this v9 of v10? (please use the topic icon to identify new posts in future as it makes it clear which version of Flowcode you are using)
And does this problem relate to simulation, the downloaded embedded code, or both?

Hi Steve,
Thanks for the quick response.
I'm using Flowcode V9 (3.1.36) Professional.
The problem occurs with the downloaded code. i'm not using simulation.

Hi Steve,
I solved the issue.
Reading the Heltec Oled datasheets revealed that there are some common problems.
According to the common problem sheet reveals issues with the first and last pixels of a line.
This is a production issue.. So fiddling with the Pixel Width or Offset X properties solves the problem.
In this case i had to shift two pixels to the right..
Learning curve...
