If anyone else has a problem to get this display to work with I2C I posted my own wiring on my blog: 2.42" I2C wiring

AndreK

So I bought one of those (2.4" display) :



I already have a project that works well with the U8X8_SSD1306_128X64 library and 0.96" displays. 

Removed R4 , jumped R3, R5

So far: I added the usual I2C Pullups and connected to an Arduino configures for the before mentioned 0.96"
also tried to pullup RES (2k2)  , pull up/down the DC (for address selection)

no success.
So I compiled it with RES support, and tried with , and without an 3k3 pullup for RES (to bring it up before arduino boots)

what else can I try ?

Thread is a little old, but for reference:

The  above 2.42" Oled with the jumpers set for I2C operation work when the reset  PIN is connected to the reset pin of the Arduino.

Used SH1109 driver in U8Gxx Lib and also dedicated SH1109 Libs

I2C:
R3 & R5 jumpered
R4 removed.

Also tested with ESP32. Just make sure to use "stickbreakers" updated wire - to avoid hangups.
