Find example code and 3D STEP in this repo.

Code examples:

• simplest_sink_example.py: A sink example code, that just picks 5V by default. Currently not tested after refactoring. It also might summon DisplayPort out of a DP source, but that's just an accident.
• sink_example.py: A sink example code, with two different strategies for picking a PD profile. Currently not tested after refactoring. It also can summon DisplayPort out of a DP source - but the PoC is not fully tested yet.
• source_example: Firmware for a bespoke board that uses the stack to create a PD PSU. Currently not tested after refactoring.
• sniffer.py: PD sniffer code. Change replay to False to run it and adjust the CC pin. Live capture not currently tested after refactoring.

Required libraries:

• fusb302.py: FUSB302 low-level code
• pdstacc.py: PD stack code
