Detailed Description

source using COMEDI

The source has one to many input stream of signed short integers.

Output samples will be in the range [-32768,32767].

Member Function Documentation

bool comedi_source_s::check_topology ( int  ninputs,
int  noutputs 
) [virtual]

Confirm that ninputs and noutputs is an acceptable combination.

Parameters:
ninputsnumber of input streams connected
noutputsnumber of output streams connected
Returns:
true if this is a valid configuration for this block.

This function is called by the runtime system whenever the topology changes. Most classes do not need to override this. This check is in addition to the constraints specified by the input and output gr_io_signatures.

Reimplemented from gr_basic_block.

int comedi_source_s::work ( int  noutput_items,
gr_vector_const_void_star input_items,
gr_vector_void_star output_items 
) [virtual]

just like gr_block::general_work, only this arranges to call consume_each for you

The user must override work to define the signal processing code

Implements gr_sync_block.
