ctrsignals.m

A graphical user interface designed to control a confocal microscope.

function CTRSignals(iDevice,Action)
% CTRSignals.
% The digital line 0 triggers the analog input, the waveform output, and
% the GPCTR_0. The GPCTR_1 generates a pulse that triggers the GPCTR_0. The
% GPCTR_0 generates a square wave train. The period and the duty cycle are defined to 
% match the X miror signal, in such a way that the laser is ON during the 
% scanning and OFF on the flyback.
%
% Input Arguments: 
% iDevice: board ID
% Action: type of action to be carried by the function
%         Start, Fast, Slow, Off, Stop
%
% Output Arguments:
%
%  Software Required:
%   MATLAB, with generic dll calling patch more information at:
%   http://www.mathworks.com/support/solutions/data/33513.shtml
