CS43L22 and LSM303DLHC

I would like to configure both the CS43L22 Audio DAC and the LSM303DLHC MEMS accelerometer to be used simultaneously. From what I have seen on the documentation, it seems that both of these devices are connected to I2C1.

Is it possible to reconfigure one of these devices to use I2C3?

Or maybe to disconnect I2C1 from the Audio DAC after the control information is sent, so that the information from the accelerometer doesn't interfere with the audio signal?

Thanks

Joe

Hello Todd,

Normally there should be no problems with having both devices on I2C1, and no interference between them, but, if you have available pins to reffer to other I2C ports, you can easily move either device to an individual port (I2C2 i.e.).

Please let me know if this helps,
