tigertool

tigertool.py is a commandline utility to control the tigertail USB-C mux. It supports changing the mux status to port A, B, or off. You can set a serial number to use multiple tigertails at once.

Usage

Typical usage to set the mux port
./tigertail.py -m [A|B|off] -s [serialno]

Reboot the tigertail
./tigertail.py --reboot

Set the serial number, when only one tigertail is plugged
./tigertail.py --setserialno=[serialno]

Tigertail can support up to 20V 3A on the mux and passes through all USB-C lines except SBU.
