Raspberry Pi Compute Module Development Kit and RTC Click


Hello! I have device called RTC Click "http://www.mikroe.com/click/rtc/" and it is connected to my Raspberry Pi Compute Module IO Board with Raspberry Pi Compute Module Development Kit. RTC Click works well with Raspberry but when I try to find under which address I can comunicate with RTC (by i2cdetect dommand) I don't get anything. I was trying to connect to different pins, enable some modules and manipulate "/boot/config.txt" file but it doesn't work. Any ideas?

I have a cheap chinese RTC module using a DS323 chip.

Don't have a compute module, but if I were in your place I'd use the regular RPI I2C pins (disconnect the compute module for now) or try using an Arduino i2c or some other microcontroller.

Try doing what these guys did, I followed the PiHut tutorial and got it to work very well.
