pymcuprog is a Python utility for programming various Microchip MCU devices using Microchip CMSIS-DAP based debuggers
Install using pip from pypi:
pip install pymcuprog
Browse source code on github
Read API documentation on github
pymcuprog can be used as a command-line interface or a library
When installed using pip, pymcuprog CLI is located in the Python scripts folder.
Example 1: test connectivity by reading the device ID using Curiosity Nano:
pymcuprog ping
Example 2: write contents of a hexfile to flash using Curiosity Nano:
pymcuprog write -f app.hex
For more examples see pymcuprog on pypi.org
pymcuprog can be used as a library using its backend API. For example:
"""
Example usage of pymcuprog as a library to read the device ID

# pymcuprog uses the Python logging module
import logging
logging.basicConfig(format="%(levelname)s: %(message)s", level=logging.WARNING)
# Configure the session
from pymcuprog.backend import SessionConfig
sessionconfig = SessionConfig("atmega4808")
# Instantiate USB transport (only 1 tool connected)
from pymcuprog.toolconnection import ToolUsbHidConnection
transport = ToolUsbHidConnection()
# Instantiate backend
from pymcuprog.backend import Backend
backend = Backend()
# Connect to tool using transport
backend.connect_to_tool(transport)
# Start the session
backend.start_session(sessionconfig)
# Read the target device_id
device_id = backend.read_device_id()
print ("Device ID is {0:06X}".format(int.from_bytes(device_id, byteorder="little")))
pymcuprog is primarily intended for use with PKOB nano (nEDBG) debuggers which are found on Curiosity Nano kits and other development boards. This means that it is continuously tested with a selection of AVR devices with UPDI interface as well as a selection of PIC devices. However since the protocol is compatible between all EDBG-based debuggers (pyedbglib) it is possible to use pymcuprog with a wide range of debuggers and devices, although not all device families/interfaces have been implemented.
pymcuprog supports:
Although not all functionality is provided on all debuggers/boards. See device support section below.
pymcuprog supports:
Other devices (eg ATmega328P, ATsamd21e18a) may be partially supported for experimental purposes
This package uses pyedbglib and other libraries for USB transport and some udev rules are required. For details see the pyedbglib package: https://pypi.org/project/pyedbglib
