UOAKV(4)                 BSD Kernel Interfaces Manual                 UOAKV(4)

NAME
     uoakv -- Toradex OAK USB +/-10V 8channel ADC interface

SYNOPSIS
     uoakv* at uhidev?

DESCRIPTION
     The uoakv driver provides support for the Toradex OAK 10V device.  The
     sensor possesses a collection of sensor values which are made available
     through the sysctl(8) interface.

     The ADC date unit is "VDC"(DC voltage) and the value is signed.  Because
     the Analog-Digital conversion cycle of the device is faster than the sen-
     sor framework update cycle, the driver keeps maximum/minimum/average val-
     ues of each cycle as independent sensors.

     The device has a unique serial number, indicated in the description part
     of the sensor value.
