1 About user manual
This manual describes the installation and usage of the Development Desktop 2.1 User Interface (DD2.1 UI); a
Windows based PC software application and related embedded firmware/software developed by Bosch Sensortec for
demonstration and evaluation of sensors.
1.1 Who should read this manual
This information is intended to users who wish to use the BME280 sensor alongside DD2.1 UI to
graphically display the Indoor Air Quality (IAQ), relative humidity, altitude, and associated components.
1.2 DD2.1 UI Overview
DD2.1 UI is a PC based software used to read, capture, and display sensor data. To display the sensor data of
BME280 on DD2.1 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. DD2.1 UI automatically detects
the sensor that has been plugged in and starts the corresponding software application.
1.3 Sensor Communication:
DD2.1 UI software supports both SPI and I
2
C to communicate with the sensor.
1.4 Graphical display:
DD2.1 UI displays the sensor data and interrupts in different graphical formats.
1.5 Data logging:
DD2.1 UI offers data logging of the sensor data.
