Introduction

• This package contains the Bosch Sensortec MEMS accelerometer sensor driver (sensor API)
• The sensor driver package includes bma2x2.h, bma2x2.c and bma2x2_support.c files
• BMA2x2 sensor driver supports the following Bosch MEMS sensors
  • BMA280
  • BMA255
  • BMA253
  • BMA250E
  • BMA22E
  • BMA220
  • BMI055 - Combination of bma2x2 + bmg160 APIs
  • BMX055 - Combination of bma2x2 + bmg160 + bmm050 APIs
  • BMC150 - Combination of bma2x2 + bmm050 APIs
  • BMC056 - Combination of bma2x2 + bmm050 APIs

Version

• Version of bma2x2 sensor driver is:

Driver files	Version
bma2x2.c	2.0.7
bma2x2.h	2.0.7
bma2x2_support.c	1.0.4

Integration details

• Integrate bma2x2.h and bma2x2.c file in to your project.
• The bma2x2_support.c file contains only examples for API use cases, so it is not required to integrate into project.

Driver files information

• bma2x2.h
  • This header file has the register address definition, constant definitions, data type definition and supported sensor driver calls declarations.
• bma2x2.c
  • This file contains the implementation for the sensor driver APIs.
• bma2x2_support.c
  • This file shall be used as an user guidance, here you can find samples of - Initialize the sensor with I2C/SPI communication - Add your code to the SPI and/or I2C bus read and bus write functions. - Return value can be chosen by yourself - API just passes that value to your application code - Add your code to the delay function - Change I2C address accordingly in bma2x2.h
    • Power mode configuration of the sensor
    • Get and set functions usage
    • Reading the sensor read out data

Supported sensor interface

• This accelerometer sensor driver supports SPI and I2C interfaces
