Hi everybody, I'm trying to build a very simply model on arduino mega 2560 board to move a servoactuator. When I press 'Build' it stops the procedure because of this error:

The corresponding 'msfun_arduino_servowrite.tlc' file for the MATLAB S-function 'msfun_arduino_servowrite' in block 'provaservu/Servo Write' must be located in the current working directory, the MATLAB S-function directory 'C:\Users\Valerio\Desktop\Tesi\Arduino0022-mavlink1.0\Arduino_simulink\demos', or the directory 'C:\Users\Valerio\Desktop\Tesi\Arduino0022-mavlink1.0\Arduino_simulink\demos\tlc_c'

I haven't any .tlc file and I don't know how to do to solve my problem.

Any ideas about that?

Thank you all!

Is this where you got your blocks from? If yes, there is a comment in the Discussion section that talks about this error:

"[The] MATLAB Support Package does not support code generation. The included Simulink blocks communicate with the Arduino in Simulink "normal" (aka. simulation) mode only.

For blocks that support code generation, see http://www.mathworks.com/academia/arduino-software/arduino-simulink.html"

Hi and thanks for helping me. I've understood your solution and now i'm using just the Arduino Target blocks. Now I've a problem with a S-Funtion that seems to be very similar to this:

http://www.mathworks.cn/matlabcentral/newsreader/view_thread/158035.

I've followed the steps adding the function and instructions about the SetInputPortDimensions but now i've a new problem with the arguments of the added function. I copy the code for explaining it better:

function sserialsb(block)

%SSERIALSB Underlying S-Function for the ICT Serial Send block.

%SSERIALSB(BLOCK) is the underlying S-Function for the ICT Serial Send

% block.

% SS 10/15/07

% $Revision: 1.1.6.5 $

% The setup method is used to setup the basic attributes of the

% S-function such as ports, parameters, etc. Do not add any other

% calls to the main body of the function.

%endfunction

I wrote ADDED to the two part of code I've added in and I don't know if I've done it well or positioned in the right place. The error I get is:

1)Error evaluating registered method 'SetInputPortDimensions' of MATLAB S-Function 'sserialsb' in 'provaprovahost/Serial Send'.

2)Invalid output port index specified for 'provaprovahost/Serial Send'. This block has no output ports

3)Error in port widths or dimensions. Output port 1 of 'provaprovahost/Constant' is a one dimensional vector with 1 elements.

Thank you for the help in advance.

I've to correct a thing that I've changed respect to the last answer i wrote. I've changed this:

%%%%%%%%%%%%%%%%%%%%%%%%%%%

%%*ADDED*

function SetInpPortDims(block, idx, di)

block.InputPort(idx).Dimensions = di;

block.OutputPort(1).Dimensions = di/2;

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

with this:

%%%%%%%%%%%%%%%%%%%%%%%%%%%

%%*ADDED*

function SetInpPortDims(block, idx, di)

block.InputPort(idx).Dimensions = di;

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

because i've just an input port and zero output port.

So then the Error now is:

1)Error evaluating registered method 'Outputs' of MATLAB S-Function 'sserialsb' in 'provaprovahost/Serial Send'.

2)An error occurred during writing.

Does it referred to the last paragraph of the code (function Outputs(block)?

Thank you again!

Valerio: I would recommend setting a breakpoint in your Outputs method and stepping through it to see what is going wrong. My guess is that error is coming from:

fwrite(serialObj, data, 'uint8');

There might be something wrong with your serial port object?
