BMI323 I2C set new address

[kaosun]

I have several BMI323 semsors need to be connected in serial on I2C so I have to set each of them with different addresses. I didn't find any info in library or from data sheet. I noticed BOSCH mentioned "Each sensor can be set to a unique I2C address, as described in the hardware description in the data sheet." Could you share some info where and how I can implement the re-addressing of them? THX!

Hi kaosun, 

Thank you for the question, sorry to tell you BMI323 I2C can not configurate to different addresses by register, it only support two I2C addresses by HW.For example the I2C address is 0x68 if the SDO pin is pulled to GND, address 0x69 is selected by pulling  the SDO pin to VDDIO.

Thanks

Thanks for quicl reply! Do you have any recommedation for any IMU supports "set I2C address"?

Hi kaosun,

Do you have engouh IO? I think you can use IO to simulate the i2c read/write. So you can use the same address, use GPIO to distinguish different sersors.

Thanks
