OLED.ino versus SDcard.ino loaded on Arduino Nano. #87

Closed JMulder99 closed 2 years ago

JMulder99 commented 2 years ago

Hi, I read the instruction manual and found the following:

Either the OLED.ino or the SDcard.ino code can be uploaded to the Arduino Nano.

Does this mean that if I want the screen to fuction, the SDcard won't function? Or vica versa, if I want data to be written to my SDcard, will the screen not function?

I noticed both programs used >50% storage during sketching.

Hi,

Yes, the libraries for running the OLED and the SDCard are both too large to fit into the Arduino’s memory at the same time.

Thanks,

Spencer

Hello, A few years ago I managed to get some firmware working using smaller libraries that supported both the display and the sd card at the same time. See here if interested. I get the feeling that it is never far from a stack crash and I no longer have access to the actual hardware to test with, so use at your own risk :).
