[@ControllersTech]

Yes there is. After selecting the I2C in the CubeMx, Keep pressing ctrl key and select that pin. CubeMx will show you the alternative for that. Just drag and drop the selection to the new pin.

if i can only set my HCLK to max of 48MHz. can that affect the scrolling? Only top part scrolls and the rest doesnt. not sure if its the code or hardware.

No, HCLK don't have any effect on scrolling. Might be the code. Try the diagonal scrolling..

im having a stm32 Nucleo G491RE can u help me with it, im unable to get it running even after changing the name in header files, what else i can d0 ?

[@ControllersTech]

@monjiro make sure you select the right pins for the i2c. Check the schematics of the board to see which pins you need to connect to. I am guessing that you have connected to the pins on the top right (scl and sda). When you enable i2c1 in cubemx, by default it will not configure these pins. You have to change the pin manually.

[@davidrosario3642]

thank u, can i use it for a i2c 128x32?

[@Pablo-ww5cn]

yes, but follow this: -open "ssd1306.c" -in line 194 change "SSD1306_WRITECOMMAND(0x3F);" to "SSD1306_WRITECOMMAND(0x1F);" -in line 203 change "SSD1306_WRITECOMMAND(0x12);" to "SSD1306_WRITECOMMAND(0x02);" if you do that, you are sending , with I2C protocol the especific command to OLED 0.91(128x32) to change 128x64 to 128x32. Otherwise it will never work.
