I just cannot make this work with any lib in I2C mode. Not sure if OLED is even working. This is the dsplay:
I have a working code which runs similar oled but with SSD1306. With first line on and SSD1306, it works. Second line on, with SSD1309 doesn't. I have soldered R15 and R13 which are supposed to turn on I2C, but I am not even sure if library supports SSD1309 in I2C mode.
//U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NONE); U8GLIB_SSD1309_128X64 u8g(U8G_I2C_OPT_NONE);
Has anyone maybe made this OLED work in I2C mode?
