Detailed Description

iio.IOBuffer class: The class used for all I/O operations.

Examples

ExampleProgram.cs.

Constructor & Destructor Documentation

IOBuffer()

iio.IOBuffer.IOBuffer ( Device dev, uint samples_count, bool circular = false )

inline

Initializes a new instance of the iio.IOBuffer class.

Parameters

dev	The iio.Device object that represents the device where the I/O operations will be performed.
samples_count	The size of the buffer, in samples.
circular	If set to true, the buffer is circular.

Exceptions

System.Exception

The buffer could not be created.

Member Function Documentation

Dispose()

void iio.IOBuffer.Dispose ( )

inline

Releases all resource used by the iio.IOBuffer object.

Call Dispose when you are finished using the iio.IOBuffer. The Dispose method leaves the iio.IOBuffer in an unusable state. After calling Dispose, you must release all references to the iio.IOBuffer so the garbage collector can reclaim the memory that the iio.IOBuffer was occupying.

Examples

ExampleProgram.cs.

Here is the call graph for this function:

Here is the caller graph for this function:

fill()

void iio.IOBuffer.fill ( byte[] array )

inline

Copy the given array of samples inside the iio.IOBuffer object.

Parameters

array

A byte array containing the samples that should be written.

The number of samples written will not exceed the size of the buffer.

first()

IntPtr iio.IOBuffer.first ( Channel ch )

inline

Gets a pointer to the first sample from the current buffer for a specific channel.

Parameters

ch	The channel for which to find the first sample.

get_device()

Device iio.IOBuffer.get_device ( )

inline

Gets the device of the current buffer.

Returns

The device of the current buffer.

push()

void iio.IOBuffer.push ( uint samples_count )

inline

Submit the samples contained in this buffer to the hardware.

Exceptions

System.Exception

The buffer could not be pushed.

read()

void iio.IOBuffer.read ( byte[] array )

inline

Extract the samples from the iio.IOBuffer object.

Parameters

array

A byte array containing the extracted samples.

refill()

void iio.IOBuffer.refill ( )

inline

Fetch a new set of samples from the hardware.

Exceptions

System.Exception

The buffer could not be refilled.

Examples

ExampleProgram.cs.

set_blocking_mode()

int iio.IOBuffer.set_blocking_mode ( bool blocking )

inline

Sets the blocking behavior of the current buffer.

Parameters

blocking

true if blocking buffer, otherwise false
