I use custom IMU board with adxl345(accelerometer) and fxas21000(gyroscope) sensors.
According to BSXlite_API_Documentation bsx_init () function need configuration arrays for every sensor.
But I don't known where to get accel_spec and gyro_spec for my sensors?
Thanks for your inquiry.
Unfortunately BSXLite only supports Bosch sensors. You may consider to switch to Bosch IMU of BMI160 or BMI088, etc.
