Is there any source code that’s available to read the raw data coming from the BMX055 sensor?
BMX055 is 3 devices in one package. See the downloads section of the product page on Bosch Sensortec’s website.
You will find the links to the 3 APIs for accelerometer, gyroscope and magnetometer data readout.
Does the BMX055 have a voltage regulator between the MEMS accelerometer and the Vss pin on the outside of the chip?
The BMX055 has 2 voltage islands, each with independent voltage regulators inside the package:
- Between VDD and GNDA : 2.4-3.6V, analog supply
- Between VDDIO and GNDIO : 1.2-3.6V, digital supply
