Hi,
I'm using an ESP-09 with a 1.3" SH1106 OLED display. I use the library from https://github.com/squix78/esp8266-oled-ssd1306 with the header file "SH1106Brzo.h".
Problem is, the columns shift randomly like in the attachment, every time i connect the PCB to the power supply. The shift only occurs, when the PCB is disconnected more than 20 sec and replugged due to a 100uF Capacitor in VCC line.
I think this may have something to do with the initialisation file "OLEDDisplay.cpp"
This is actually provided with the library. Does it miss something, that has to be set?

Code: Select all

sendCommand(SETDISPLAYCLOCKDIV);
sendCommand(0xF0); // Increase speed of the display max ~96Hz
sendCommand(SETMULTIPLEX);
