spinnman.extended.extended_transceiver module

class spinnman.extended.extended_transceiver.ExtendedTransceiver[source]

Bases: object

Allows a Transceiver to support extra method not currently needed.

All methods here are in danger of being removed if they become too hard to support and many are untested so use at your own risk. It is undetermined if these will work with Spin2 boards.

If any method here is considered important to keep please move it to Transceiver and its implementations
