function h = rtdx(bpnum)
%RTDX Construct RTDX(tm) (Real-Time Data Exchange) object.
% R = RTDX(DSPTASK) returns a handle to an RTDX object constructed
% by inheriting the Code Composer Studio(tm) (CCS) API class 'DspTask'
% defined in the CCSDSP object. The handle to 'DspTask' interface is
% traversed to get the 'Rtdx' class interface. 'Rtdx' handle is used to get
% handles to 'RtdxChannel' interfaces by the OPEN method. This constructor
% defines the object properties data structure to store RTDX and RTDX channel
% handles and other identifying attributes.
%
% BPNUM - 2 element Vector of board
%
% Public read-only properties (use GET):
%
% .numChannels number of open RTDX channels
% .RtdxChannel{i,1} channel name of i-th channel, 1 <= i <= numChannels
% .RtdxChannel{i,3} read/write mode ('w'/'r') of i-th channel
% .procType integer specifying DSP type (e.g., C62, C67, C54)
%
% Public read/write properties (use GET/SET):
%
% .timeOut global time out value in seconds used for RTDX accesses
%
% Private properties (no direct access to users):
%
% .Rtdx handle to ActiveX RtdxChannel sub-class
% .RtdxChannel{i,2} interface handle to i-th channel
%
% Accesses to Texas Instruments(tm) (TI) CCS and target TI DSPs via RTDX are
% initiated by the instantiation of MATLAB objects of class CCSDSP and RTDX.
% Once the objects are constructed, various remote automation tasks may be
% performed by calling predefined object methods, which get, manage, and
% release necessary CCS API interfaces through Windows ActiveX. The list of
% supported methods can be displayed typing "help rtdx" at the MATLAB command
% command line.
