Hi，TI

The address of 948 is the same，will there be a conflict by configuring the 948 through the same I2C?

The slave devices can configure slave ID and slave alias to avoid conflict issues.

The configuration of the 948 conflicts which registers of the configuration 947 to avoid？

Hi Zhijian,

This configuration should be fine. I will double check with team and let you know.

Best,

Hi Zhijian,

Since the address of the 948s are the same, one of them will need to have a slave alias set up in 947 like the other slave devices on the bus. Hope this helps.

Best,

Shu

Hi Shu

How to set the slave alias of 948？Can it also be done through slave ID [x] and slave Alisa [x] registers？

How to configure the registers of 947 to change the address of 948.

The current phenomenon is that only one 948 register is configured, and eventually both 948s are configured.

Hi Zhijian,

Yes the Slave ID [x] and Slave Alias [x] registers of the 947 is used to set the address of the 948s and then their individual aliases.

For example, in the 947 you would set Slave ID as 0x2C (actual address of the 948) and then set the corresponding Slave Alias register to what you wish the alias address to be.

Best,

Shu
