Multiple BNO085's

Sensors IMU & Motion
1

I wanted to use multiple BNO085’s with the STM32 using SPI Daisy Chain. I’d found a GitHub repo of a modified Sparkfun Arduino BNO080 library, modified to work with the STM32- The repo. I tried to modify this library to work with multiple BNO’s but I’m unable to get it working.

Changes made:

  • Created a structure to share the variables between both of the IMU’s
  • Created instances of both the IMU’s
  • Passed functions with the structure parameters so that the functions are called separately for both the IMU’s
  • Separate CS Pins and INT Pins used for the two IMU’s

Issue’s faced:

I get the default quaternion values i.e., 0,180,360. Unable to get live values.

This is my repo, My repo

I would appreciate any help on this.
