bmx160_fix.bash

#!/bin/bash

# This script is intended to workaround the issue where Bosh recommends using the BMI160 library
# for the BMX160 as well, however they have not updated the library to work with the chip IP that
# is used for the BMX160. This script modifies the defines to allow us to provide a custom chip
# id when necessary.
# Expected use:
#     ./bmx160_fix.bash "libs/BMI160_driver/bmi160_defs.h"
# Note: Once the file has been fixed, it still needs a define for the BMX160 chip id. eg:
#     DEFINES+=BMI160_CHIP_ID=UINT8_C\(0xD8\)
