Python wrapper for coinesAPI
Project description
COINESPY
: Interface for Bosch Sensortec's Engineering Boards.
COINESPY
provides a python interface for interacting with the Bosch Sensortec's Engineering boards.
The library offers the following range of functionalities:
- Control VDD and VDDIO of sensor
- Configure SPI and I2C bus parameters
- Read and write into registers of sensors from Bosch Sensortec via SPI and I2C
- Read and write digital pins of the Engineering Board.
Engineering Board driver installation
To install the driver for the Engineering Board, follow these steps:
- Navigate to the USB driver location:
<path_to_python_site_packages>\coinespy\driver
. - Run the USB driver.
Firmware update
Prerequisites
Before proceeding, ensure that the selected Engineering Board is flashed with either Coines bridge
or DD
firmware.
Steps to update firmware
To update the Coines bridge
firmware to the Engineering Board, follow these steps:
- Open the
firmware
folder located at<path_to_python_site_packages>\coinespy\
. - Select the appropriate subfolder that corresponds to your specific board type.
- Run the provided .bat/.sh file within the selected subfolder to initiate the firmware update process.
Configuration for BLE communication
Windows
To enable Bluetooth Low Energy (BLE) communication with coinespy Python library on a Windows machine, users need to modify their environment variables after installing the package. Based on the PC's architecture, add one of the following paths to your environment variables.
- 64-bit:
<path_to_python_site_packages>\coinespy\bin\x64
- 32-bit:
<path_to_python_site_packages>\coinespy\bin\x86
Linux/MacOS
For BLE communication in Linux and MacOS, no additional configuration is necessary.
Note
To determine the installation directory of coinespy, use pip show coinespy
. Replace <path_to_python_site_packages>
with your Python site packages directory.
Code example
Here’s a script to verify the installation by fetching the COINESPY version, and the hardware and software versions of the connected board.
import coinespy as cpy
from coinespy import ErrorCodes
COM_INTF = cpy.CommInterface.USB
if __name__ == "__main__":
board = cpy.CoinesBoard()
print('COINESPY version - %s' % cpy.__version__)
board.open_comm_interface(COM_INTF)
if board.error_code != ErrorCodes.COINES_SUCCESS:
print(f'Could not connect to board: {board.error_code}')
else:
b_info = board.get_board_info()
print('BoardInfo')
print(f'Software ID: v{(b_info.SoftwareId >> 12) & 0xF}.{(b_info.SoftwareId >> 6) & 0x3F}.{b_info.SoftwareId & 0x3F}')
print(f'Type of Board: {hex(b_info.Board)}')
board.close_comm_interface()
