Generic Tests

Functions used by test fixtures for evaluating drivers without pyadi-iio classes or not by using pyadi-iio classes.

test.generics.iio_attribute_single_value(uri, attrtype, dev_name, chan_name, inout, attr, start, stop, step, tol, repeats=1)

iio_attribute_single_value: Test numeric attributes over ranges This is a generic test that does not use pyadi-iio classes but instead uses libiio directly.

parameters:

uri: type=string

URI of IIO context of target board/system

attrtype: type=string

Name attribute type to test. Options are: context, channel, debug, device, and channel

dev_name: type=string

Name device with associated attribute. Ignored if not device, debug, or channel attribute under test

chan_name: type=string

Name of channel if channel attribute. Ignored if not channel attribute under test

inout: type=boolean

True if output channel, False otherwise. Ignored if not channel attribute under test

attr: type=string

Attribute name to be written. Must be property of classname

start: type=integer

Lower bound of possible values attribute can be

stop: type=integer

Upper bound of possible values attribute can be

step: type=integer

Difference between successive values attribute can be

tol: type=integer

Allowable error of written value compared to read back value

repeats: type=integer

Number of random values to tests. Generated from uniform distribution

test.generics.iio_buffer_check(phy, rxdev, uri, percent_fail)

iio_buffer_check: Check receive buffers for repeative patterns of zeros. This function does not require an interfaces class in pyadi but will construct a generic interface on the fly.

parameters:

phy: type=string

Name of PHY IIO driver

rxdev: type=string

Name of driver with scan elements to create buffers with

uri: type=string

URI of IIO context of target board/system

percent_fail: type=float

Allowable percentage of zeros at a given index of collected buffers
