I just bought a 160x128 pixel OLED display to play around with.
I have read the datsheet found here:
http://www.farnell.com/datasheet... (pg. 37)
I'm not sure I read the supply voltages corretly:
Do I need to put 3.3V on VDD, and 8-18V on VDDH? I'm don't understand why the high voltage, I don't want to fry it, because it cost a good deal of money.
Also there is an application note here:
http://www.farnell.com/datasheet... (pg. 4)
In the schematics it seems like putting JP2 would shourt VDD (with VSS), as VDDIO is connected to VDD (see JP1). I don't understand the purpose of JP1 either, they two pins are actually connected to the right, so what's the pint?
And if I really need 8-18V on VDDH, how can I transform my 5V supply voltage up into the valid area?
Thanks for your help,
