Firstly I want to compliment Manuel and Guido for such an impressive Work. Sharing your project to the World in such a way is only something Radioamateurs will do, and we are proud of it. And yes, radioamateurs can’t help to tinker… that is why I decided to make some modifications to the initial setup, but having the screen a few inches away from its original place.
This has produced some side effects on the reliability of the Oled screen. Whereas with standard position or with 4cm cable it was ok.
My test have been made using a 15cm length wire. Symptoms:
- Occasional misalignment of characters
- Vertical lines
- Character size changes
- Reversed orientation
- Glitches
- Nothing on the screen
Powered by usb or 12V
I have tested with a screened wire with no success.
I see it is a common problem with I2C protocol… Some people shared this issue here https://forum.arduino.cc/t/128x64-oled- ... ion/610179
I will do more tests
