Channel{T <: AbstractDeviceOrTrigger} <: AbstractChannel

Represents a channel of an IIO device.

Channel(dev::AbstractDeviceOrTrigger, channel::Ptr{iio_channel})

Initializes a new instance of the Channel type.

Parameters

• dev::AbstractDeviceOrTrigger : The parent device handle (Device or Trigger)
• channel::Ptr{iio_channel} : A valid pointer to an IIO channel.

Returns

• A new instance of this type

ChannelAttr <: Attr

Represents an attribute of a IIO channel

ChannelAttr(chn::Ptr{iio_channel}, name::String)

Initializes a new instance of a ChannelAttr.

Parameters

• chn::Ptr{iio_channel} : A valid pointer to an iio_channel
• name::String : The channel attribute's name

Returns

• A new instance of this type

read(chn::AbstractChannel, buf::AbstractBuffer, raw=false)

Extract the samples corresponding to this channel from the given buffer.

Parameters

• chn::Channel : The channel instance
• buf::AbstractBuffer : A buffer instance
• raw::Bool: If set to true, the samples are not converted from their native format to their host format

Returns

• A Vector{Cuchar} containing the samples for this channel

read(chn::AbstractChannel, buf::AbstractBuffer, data::Vector{T}, raw=false) where {T}

Write the specified vector of samples into the buffer the specified channel.

Parameters

• chn::Channel : The channel instance
• buf::AbstractBuffer : A buffer instance
• data::Vector{T} : A data vector containing the samples to copy
• raw::Bool: If set to true, the samples are not converted from their host format to their native format

Returns

• The number of bytes written

attrs(chn)

List of attributes for the given channel.

data_format(chn)

Returns the channel data format as a C-struct. See iio_data_format.

device(chn)

Retrieves the corresponding AbstractDeviceOrTrigger for this channel.

enabled!(chn, state)

Sets the channel state to enabled if true, disabled otherwise.

enabled(chn)

Returns true if the channel is enabled, false otherwise.

id(chn)

An identifier of this channel. Note that it is possible that two channels have the same ID, if one is an input channel and the other is an output channel.

index(chn)

Returns the index of the channel.

modifier(chn)::iio_modifier

Returns the channel modifier as an enum value.

output(chn)

Contains true if the channel is an output channel, false otherwise.

scan_element(chn)

Contains true if the channel is a scan element, false otherwise.

type(chn)::iio_chan_type

Returns the channel type as an enum value.
