I receive the following error message when trying to open the Arduino Engineering Kit library in Simulink

     Warning: An error occurred while parsing
  "C:\Users\konta\OneDrive\Dokumente\MATLAB\Add-Ons\Toolboxes\Arduino_Engineering_Kit_Hardware_Support_18b\simulink\blocks\slblocks.m".
  Error Message: Invalid arguments in the message cell. They should be of type 'character vector',
  'float' or 'integer'.

Is there anything that I can do against this error? I tried reinstalling the Arduino Engineering Kit Hardware Support package, which did not help.

Are you on MATLAB R2018b or R2018a?

R2018b

This is the function that Simulink is trying to call:

function blkStruct = slblocks
% SLBLOCKS Defines the block library for MKR Motor Carrier and Sensors
% libraries



blkStruct.Name = sprintf('ArduinoEngineeringKit');
blkStruct.OpenFcn = {'arduinosensorlib', 'mkrmotorcarrierlib'};
blkStruct.MaskInitialization = '';
blkStruct.MaskDisplay = 'disp(''ArduinoEngineeringKit'')';

Browser(1).Library = 'mkrmotorcarrierlib';
Browser(1).Name    = sprintf('Simulink Support for Arduino MKR Motor Carrier');
Browser(1).IsFlat  = 0; % Is this library "flat" (i.e. no subsystems)?

% Define information for model updater
blkStruct.ModelUpdaterMethods.fhSeparatedChecks = @ecblksUpdateModel;

% LocalWords:  Arduino Engineering Kit

Thanks Nicholas for catching this bug. I did the following and fixed the errors -

1) remove the arduinosensorlib reference in line 8. The following should be changed from 'blkStruct.OpenFcn = {'arduinosensorlib','mkrmotorcarrierlib'};' to 'blkStruct.OpenFcn = {'mkrmotorcarrierlib'};'

2) add the following line of code in line # 15

blkStruct.Browser = Browser;

After this I closed and reopened MATLAB and the errors went away. I will work with internal teams to get this updated in the File Exchange as well.

Thanks a lot for the help! It works perfectly now.
