1. About this user manual
This manual describes the installation and usage instructions of Development Desktop 2.0, User Interface (DD2.0 UI) a Windows based PC software application developed by Bosch Sensortec for demonstration and evaluation of the BMX055 accelerometer and gyro sensor.
1.1 Who should read this manual
This information is intended for users who want to implement a robust BMX055 functionality.
1.2 DD2.0 UI Overview
DD2.0 UI is a PC based software used to read, capture, and display sensor data. To display the sensor data of BMX055 on DD2.0 UI, mount the sensor on the Bosch Sensortec application board. This is a universal demonstration environment for Bosch Sensortec sensor products.
Bosch Sensortec sensors are mounted on sensor specific shuttle boards. All sensors shuttle boards have an identical footprint and can be plugged into the application board’s shuttle board socket. DD2.0 UI automatically detects the sensor that has been plugged in and starts the corresponding software application.
1.3 Sensor Communication:
DD2.0 UI software supports both SPI and I2C to communicate with the sensor.
1.4 Graphical display:
DD2.0 UI UI displays the sensor data and interrupts in different graphical formats.
1.5 Data logging:
DD2.0 UI offers data logging of the sensor data.

2. About the BMX055
The BMX055 consists of BMA255, BMG160 and BMM150 in a single chip.
BMA255 is an advanced, ultra-small, tri-axial, low-g acceleration sensor with digital interfaces, aiming for low­power consumer electronics applications. Featuring 12 bit digital resolution, the BMX055 allows low noise measurement of accelerations in 3 perpendicular axes and thus senses tilt, motion, shock and vibration in cellular phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features and game controllers.
The BMG160 is a three-axes-gyroscope device. It consists of a MEMS element and an ASIC within one package. It is capable to measure angular rates in three perpendicular room dimensions X, Y and Z-axis and to provide the corresponding the output signals
BMM150 is a three axis MEMS magnetometer. The magnetometer measures the components of the earth’s magnetic field (the geomagnetic field).
The packaging and interfaces of the BMM150 have been designed to match a multitude of hardware requirements. As the sensor features an ultra-small footprint and a flat package, it is ingeniously suited for mobile applications.
The BMM150 offers ultra-low voltage operation (VDD voltage range from 1.62V to 3.6V, VDDIO voltage range
1.2V to 3.6V) and can be programmed to optimize functionality, performance and power consumption in customer specific applications. The programmable interrupt engine sets new standards in terms of flexibility.
The BMM150 senses data ready, low threshold, high threshold and overflow in cell phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features and game controllers. BMM150 sensor specific details can be referred in BMM150 sensor data sheet.
