dronecan

✓ import dronecan

Standard import.

Initialize a DroneCAN node on a SLCAN interface, subscribe to NodeStatus, and spin.

import dronecan # Initialize a node node = dronecan.make_node('slcan0', node_id=100, bitrate=1000000) # Start node node.start() # Subscribe to node status messages def on_node_status(msg): print(msg) node.add_handler(dronecan.uavcan.protocol.NodeStatus, on_node_status) # Spin forever import time while True: try: node.spin(timeout=1) time.sleep(1) except KeyboardInterrupt: break node.close()

Debug

Known issues

gotchaThe import path for DSDL types changed. Use `dronecan.uavcan.protocol.NodeStatus` instead of `dronecan.node.NodeStatus` after DSDL compilation.

fix

Use `from dronecan.uavcan.protocol import NodeStatus` after compiling DSDL.

affects: >=1.0.0

breakingIn Python 3.11+, the slcan driver may have issues. A fix was applied in v1.0.18, but ensure you are using a supported python-can version.

fix

Upgrade to dronecan >=1.0.18 and ensure python-can is up-to-date.

affects: <=1.0.17

deprecatedThe old `dronecan.driver.slcan` driver is deprecated in favor of `dronecan.driver.slcan.Serial`.

fix

Use `dronecan.driver.slcan.Serial` instead of `dronecan.driver.slcan`.

affects: >=1.0.20

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'dronecan.uavcan'

Missing DSDL compilation or using wrong import path.

fix

Run `dronecan_dsdlc <path-to-dsdl-dir>` to compile DroneCAN DSDL definitions first.

AttributeError: module 'dronecan' has no attribute 'make_node'

Using an older version of dronecan that does not have `make_node`.

fix

Upgrade dronecan to >=1.0.0 with `pip install --upgrade dronecan`.
