What do you get when you run i2cdetect -y 0

It should give you a list of devices and their addresses like so:

0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: 30 31 32 33 34 35 36 37 -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: 50 51 52 53 54 55 56 57 58 59 5a 5b 5c 5d 5e 5f 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- Identify the ones you know are connected and the one you cannot identify will be the RTC. If you are thinking the Omega has an RTC built in, then you are mistaken. You would need to hook one up to the i2c bus to be able to use one.

The PCF8574 break-out board, is an 8 port GPIO extension.
So i cannot read the I2C bus with above program...

I need more inputs on the Omega2, so i was hoping to solve it this way.

I tried the One-Wire system before, but also no luck (device not recognised)...

Hi guys,

I was too busy since I created the topic and did not follow your answers
@Lazar-Demin I am glad there is a fix to this bug and I am sorry I was not able to provide what you asked for. In the comming days I will try to test the new firmware and confirm the problem resolved.

Cheers!
