lenz-flashtool

FlashTool library for BiSS C Firmware Update and Calibration by LENZ Encoders.

This is the source repository for the lenz-flashtool Python package, designed to interface with LENZ BiSS C encoders for firmware updates, calibration, and data reading. It provides a FlashTool class and utility functions for working with encoder hardware, including hex file manipulation and color formatting utilities.

Features

• Control LENZ BiSS C encoders via serial communication.
• Upload firmware and calibration data.
• Read encoder status, serial numbers, and error flags.
• Utilities for CRC calculation, hex data generation, and colored logging output.

Installation

From local folder

pip install .

From PyPI

pip install lenz-flashtool

From GitHub

pip install git+https://github.com/lenzencoders/lenz-flashtool-lib.git

Requirements

• Python 3.8 or higher
• pyserial>=3.5 (for serial communication)
• numpy>=1.21.0 (for data handling)

Usage

Basic Example

from lenz_flashtool import FlashTool, init_logging

# Set up logging
#
# Level	            Integer Value
# logging.CRITICAL	50
# logging.ERROR	    40
# logging.WARNING	  30
# logging.INFO	    20
# logging.DEBUG	    10
# logging.NOTSET	  0
init_logging(logfilename="flashtool.log", stdout_level=20, file_level=10)

# Initialize FlashTool
with FlashTool(port_description_prefixes=('XR21V')) as lenz:
    # Power cycle the encoder
    lenz.encoder_power_cycle()

    # Read serial number
    bootloader_ver, serial_num, mfg_date, program_ver = lenz.biss_read_snum()
    print(f"Encoder Serial Number: {serial_num}")
# The connection is automatically closed when exiting the 'with' block

Note on Naming

The package is installed as lenz-flashtool (with a hyphen), but imported in Python as lenz_flashtool (with an underscore) due to Python’s naming conventions.
