MATLAB Support Package for Arduino (aka ArduinoIO Package)

MATLAB class and Simulink blocks for communicating with an Arduino microcontroller board

getSetupBlockUserData(modelHandle, arduinoVar)
% getSetupBlockUserData(modelHandle, arduinoVar)
%  Searches the model for the Arduino IO block specified by <arduinoVar> (e.g., 'Arduino1')
%  and returns the userdata of that block. Throws an error if there isn't a unique
%  match for the block or if the userdata is empty.
%  modelHandle can be a string or a numeric handle 
%  arduinoVar is a string, corresponding to the arduinoVar parameter (e.g., 'Arduino1')
% Example:
%  customData = getSetupBlockUserData(bdroot(gcb), 'Arduino1');
%  customData = getSetupBlockUserData(bdroot(block.BlockHandle), block.DialogPrm(1).Data); % in a M S-fcn
