NAME¶

iio_writedev - write buffers on an IIO device

SYNOPSIS¶

iio_writedev [ options ] [-n <hostname>] [-t <trigger>] [-T <timeout-ms>] [-b <buffer-size>] [-s <samples>] <iio_device> [<channel> ...]

DESCRIPTION¶

iio_reg is a utility for writing buffers from connected IIO devices.

OPTIONS¶

-h, --help

Tells iio_readdev to display some help, and then quit. -n, --network Use the network backend with the provided hostname

-u, --uri

The Uniform Resource Identifier (uri) for connecting to devices, can be one of:

-t --trigger

Use the specified trigger, if needed on the specified channel

-b --buffer-size

Size of the capture buffer. Default is 256.

-s --samples

Number of samples (not bytes) to capture, 0 = infinite. Default is 0.

-T --timeout

Buffer timeout in milliseconds. 0 = no timeout. Default is 0.

-a, --auto

Scan for available contexts and if only one is available use it.

-c --cyclic

Use cyclic buffer mode.

RETURN VALUE¶

If the specified device is not found, a non-zero exit code is returned.

USAGE¶

You use iio_readdev in the same way you use many of the other libiio utilities. You must specify a IIO device, and the specific channel to read. Since this is a write, channels must be output. It is easy to use iio_attr to find out what the channels are called.

This identifies the device, and channel that can be used.

This sends 1024 samples of I and Q data to the USB attached AD9361. data is taking from standard in, in a binary format.
