First time for OLED, HELP NEEDED!
I just bought the NHD-3.12-25644UCB2 OLED for a project and I don't have much experience with the OLED before. To do a test run, I just connected the 3.3v power supply and ground to the VDD and VSS pin to see if the OLED works but nothing happened, as I expected there should be something like a cursor blinking however the screen is just black. Did I do something wrong with it ? I know this is a super dumb question. Do I need to set up the SPI in my PIC controller to give SCLK clocks to the OLED then it can show something?
This is kind of emergency project. Thank you so much in advance for your time.

Hi Lin,
The OLED you bought is a graphic display, there wouldn't be a cursor blinking. Before you are able to write to the display, you need to first initialize the display and then provide the pixel data.
You can use this example code to help you get started with programming the display and having it display data: https://newhavendisplay.com/content/app_notes/OLED_25664.txt
I am curious if you were interested in a Character OLED vs. the Graphic because you mentioned the blinking cursor. If this is the case I would recommend taking a look at either the standard Character OLED display or the Slim OLED displays.
