Low memory / Display Issues

[GruvyPigeon]

I have a Arduino uno and im getting the message Low memory available, stability problems may occur.
And my display is not working properly. my display is 128x64 oled and has the inputs GND VDD SDK SDA.
Can I use my display or shoud I get a display with GND VCC SDL SDA?

@GruvyPigeon
The message regarding the memory is not a cause for concern at first and is also displayed for me. It is displayed as soon as more than 75% of the RAM is used.

Which display exactly do you want to use? Do you have a link to the display data sheet?

@GruvyPigeon Currently only displays with SSD1306 controller are supported. Your display uses a SSH1106 controller. It seems that they are not that much different, but it won't be working without some code changes.
Either you make the necessary changes to the code :-)
or, if you buy a display with SSD1306 (SSD1309 should also work without changes) then I would recommend SPI instead of I²C, because you can get more fps out of it.
