File Information
Description

DAQSTOPBUTTON(FIG,OBJ) adds a start/stop button to figure FIG. This button can be used to start and stop data acquisition object OBJ. DAQSTOPBBUTTON will also delete OBJ when FIG is closed (i.e., it sets FIG's CloseRequestFcn to delete the object).
 
DAQSTOPBUTTON(FIG,OBJ,'P1','V1','P2','V2', ...) specifies Property-Value pairs for configuring properties of the start/stop button. Any valid property of a togglebutton can be specified.
 
HBUTTON = DAQSTOPBUTTON(...) returns a handle to the start/stop button.
 
  Example:
       fh = figure; % Create a figure
       ai = analoginput('winsound'); % Create an input object
       addchannel(ai,1); % Add a channel
       set(ai,'TriggerRepeat',inf); % Configure to run infinitely
       set(ai,'TimerFcn','plot(peekdata(ai,500))'); % Each timer event will plot recent data
       hButton = daqstopbutton(fh,ai); % Add the stopbutton

Can you demonstrate if this works when we have GUIDE START pushbutton? I wouldlike to do continuous session based acquisition.

Is there anyway to make the text on the button change from start to stop when it is toggled? Thanks!
