Audio adapter and RTC

[lorencc]

Both use SDA & SCL. Is there a proper way to use both?

[MichaelMeissner]

Both use SDA and SCL as the i2c bus #0. I2c is a shared bus, and as long as every device on the bus uses a different address and meet the various electrical requirements like relatively short cables, same voltages, etc., everything is fine.

Lets see, the Audio Adapter has 2 i2c devices (SGTL5000 with address 0x0A and WM8731 with address 0x1A). DS3231 real time clocks typically use 0x68 for the RTC, and 0x50-0x57 for EEPROM. So they should work together.

Thanks for the info.
