I solderd OLED FPC cable to board. Then connected it to ESP32 dev baord and nothing happend.

I was depressed and didn't know what to do next. All what came up is checking datasheet and checking voltage of each pin.

When I compared pin table of datasheet and schematic, it turns out the symbol I used is not for my OLED panel.
Guessing from pin names, it seems like I referenced SH1106 version when I created the symbol.

I was able to patch circuit and now it works. Pins marked with red needs to be connected to GND and green pins are connected to GND, I added jumper cable to connect them
