Hi All,

I'm new to OLED displays but have used the Nokia 5110 in couple of my
previous projects. I believe that they both work the same way (SPI-
Data in, CLK in, CS, D/C, RST) , just the init sequence is a bit
different.

I believe that CS signal can be omitted if there is only one device on
the SPI bus. If I tie it low, the display will always be selected and
any transaction on the SPI bus will be directed towards the OLED
display. This way I can save a signal pin, would there be any issues?


Thanks,
