Bases: object

Extended version of the Facedancer class that accepts a direct SPI connection to the MAX324x chip, as used by the Raspdancer.

__init__(verbose=0)

Initializes our connection to the MAXUSB device.

reset()

Resets the connected MAXUSB chip.

set_up_comms()

Sets up the Raspdancer to communicate with the MAX324x.

ack_status_stage(blocking=False)

Handles the status stage of a correctly completed control request, by priming the appropriate endpoint to handle the status phase.

Parameters:

• direction – Determines if we’re ACK’ing an IN or OUT vendor request. (This should match the direction of the DATA stage.)

• endpoint_number – The endpoint number on which the control request occurred.

• blocking – True if we should wait for the ACK to be fully issued before returning.
