If you’ve got an original Model B Rev 1 Pi then type the following command instead :

i2cdetect -y 0




This was good news as it showed the device had been detected with an address of “0x3c”. This is the default hex address for this type of device. I’ve got no idea why the device PCB suggests the address is “0x78” when it is clearly “0x3c”.
