coinespy 1.0.6

Python wrapper for coinesAPI

COINESPY: Interface for Bosch Sensortec's Engineering Boards.

COINESPY provides a python interface for interacting with the Bosch Sensortec's Engineering boards.

• GitHub repository
• Documentation
• Examples

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()
