OLED v1.2 and v1.2 on Hydra

Archive

Hello,

What is the difference between the OLED versions 1.1 and 1.2 ?

I have a collection of both OLED versions and it would appear that the v1.1 does not work on the Hydra. (Netmf 4.2)

  • no compile/runtime errors
  • first display update will show a distorted image (tested with text on screen)
  • subsequent display updates leave the screen blank.

Regards
Steven

I have compared 1.1 and 1.2 schematics and they look exactly the same. There are insignificant trace size changes on boards. Other than that looks exactly same to me.

Hello,

I am still getting errors with my OLED v1.1

Mainboard: Hydra 4.2 (full info below)

I can display an image in both JPG and BMP and the v1.2 OLED displays it as expected.

The v1.1 OLED shows the same image staggered (for both JPG and BMP)

Also for some reason I get an exception on GIF (but I guess that is a different issue) – anyone got Gif working on Hydra + OLED?

I have attached the display output. The picture is static and not flickering as you may thing from the images, it is just more like a timing issue.
