Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
This driver implements support for the ChargerLAB POWER-Z USB-C power testing
|
||
|
|
family.
|
||
|
|
|
||
|
|
The device communicates with the custom protocol over USB.
|
||
|
|
|
||
|
|
The channel labels exposed via hwmon match the labels used by the on-device
|
||
|
|
display and the official POWER-Z PC software.
|
||
|
|
|
||
|
|
As current can flow in both directions through the tester the sign of the
|
||
|
|
channel "curr1_input" (label "IBUS") indicates the direction.
