OLED I2C adress
Posted: 19 Nov 2022, 12:44
Hello guys,
As I noticed, there are OLED displays with different I2C addresses. Maybe this is my problem, because after installing the bootloader with the ISP programmer, the display shows nothing (no serialnumber).
However, the display works and has the I2C address 0x78. There are also OLEDs with an I2C address of 0x3C.
Is it possible that the bootloader on the DL2MAN (tru)sdx homepage needs a display with the address 0x3C?
With kind regards
