Bosch Sensortec COINES

COmmunication with INertial and Environmental Sensors

COINES allows users to evaluate sensors using the Bosch Sensortec Application Board. Sensor configuration and data readout can be easily done using the coines_api from PC side using C (or) Python.

To overcome the limitations (Eg: inaccurate delays,etc.,) due to latencies in USB communication, some C examples can also be cross-compiled and run directly on the Application Board's microcontroller.

Quick Start

• Clone this repository
• Install GCC Toolchain and GNU Make
• Install USB drivers and libraries
  • Windows - app_board_usb_driver.exe
  • Linux - libusb-dev package and udev rules
    • Debian based distros - sudo apt install libusb-1.0-0-dev
    • Red Hat based distros - sudo yum install libusbx-devel
  • macOS - brew install libusb
• Connect the Bosch Sensortec Application Board 2.0 (or) 3.0 to PC with any sensor shuttle mounted.
• Go to any example and run make (Eg: template/c)
• Run the compiled binary

Running examples on Application Board microcontroller

• Update to the latest DD2.0 firmware ( v3.1 and above )
• Install dfu-util
  • Windows - Not required.Available at util/usb-dfu
  • Linux
    • Debian based distros - sudo apt install dfu-util
    • Red Hat based distros - sudo yum instal dfu-util
  • macOS - brew install dfu-util
• Get GNU Arm Embedded Toolchain, extract and add to PATH
• Go to any example and run make TARGET=MCU_APP20 download (or) make TARGET=MCU_APP30 download (Eg: template/c)
• Open Application Board USB serial port with any serial terminal program (Ensure DTR signal is asserted)

Installing and using coinespy

coinespy can be used to access the Application Board via Python

• Install Python 3.x
• Install coinespy by using any of the below command set.

  $ pip install coinespy

  $ cd coines_api/pc/python
  $ python setup.py install

• Go to template/python and run coinespy_test.py

Creating new examples

• For creating new examples, see template/c
• Use template/c/Makefile as a reference for including additional C, Assembly, C++ files and binary libraries.
