What is the correct voltage terminology for VDD and VSS?
I've been installing a Winstar WEH001602D OLED and was struggling until I realised that it appears to have pins 1 and 2 reversed compared to the usual convention. It requires +5 V DC on pin 1 and 0 V on pin2.
However in the abbreviated data sheet it says "pin 1, VDD, Ground Pin" and "pin 2, VSS, Voltage for logic" whilst the website says "pin 1, VDD, Supply Voltage for logic" and "pin 2, Vss, Ground Pin".
The WEH001602D's that I have definitely have the two pins reversed, though.
