Sample capture for the software team:
System startup capture file with two I2C channels on different systems each with a HLA analyser decoding TUSB422 traffic and traffic to a MCP23017 I/O expander. There are also two active async serial 912600 baud serial streams giving system status information for the two systems.
One system is a data acquisition system using USB 2 full speed over USB-C with Power Delivery to negotiate 5V at 10W. The other system is in essence a four port 100W per port USB-C hub with a little extra proprietary magic.
The capture shows the cable connect through to completion of power and proprietary alternate mode negotiation over USB-C PD.
Note that the CC2 line actually shows the Manchester encoded PD communication between the devices.
