• Parallel To Serial Conversion

After issues I met, trying to read from COM port with Simulink, as I wrote in this discussion, I would like to follow Phil Goddard's suggestion on writing a C S-function for that. My problem is that I am not able to write C-code, so I hope in some help from you.I have found this two scripts on the net about C S-function for serial communication:

Hi I would like to ask where to find examples of serial code conversion to parallel using Parallel Computing Toolbox. Specifically I want to convert a serial matlab algorithm, which simulates fire spreading using cellular automata. I found some very simple examples at official site of Mathworks but it is not what i' m looking for. 1 serial peripheral interface. MATLAB Compiler Simulink Coder Simulink HDL.

But when I try to compile it by mex sfun_comport.c it returns following errors:

This produces:

As you can notice common errors between two S-function are about:

Do you have some suggestion to fix those errors ?

PS: I have MATLAB 2013b 64-bit, 64-bit Windows 7, Microsoft Visual C++ 2010 (32-bit) as compiler (it has worked fine in 64-bit matlab to produce mex files)

You still have to write those functions by yourself. As you can see from their names, they define the sizes and sample time of the S-Function. They are required components of a complete and functional S-Function.

Users can select individual maps in areas of interest and transfer the maps to a compatible GARMIN GPS unit. Garmin MapSource CD's Garmin MapSource TM CD's MapSource TM products feature geographic Electronic Base Map Data plus Trip & Waypoint Management Software on CD-ROM. Electronic Base Map Data This data augments the information already on the electronic basemap compatible GARMIN GPS units and is sold as an accessory. Mapsource cd rom download.

For example:

static void mdlInitializeSizes(SimStruct *S) describes the sizes information that is used by Simulink to determine the S-function block's characteristics (number of inputs, outputs, states, etc.).

static void mdlInitializeSampleTimes(SimStruct *S) is used to specify the sample time(s) for your S-function.

Discrete-time serial-in, parallel-out shift register

• Library:

• Simscape / Electrical / Control / General Control

Description

The Serial-In Parallel-Out Shift Register block implements a serial-in parallel-out shift register in discrete time. You can use a shift register to convert between serial and parallel interfaces or to implement a circuit delay or hardware stack.

This block outputs a vector of last N samples of the input signal. If the input signal is a vector, the block outputs the last N samples of each input signal.

Ports

Output

Parallel output signal.

Data Types: singledouble

Parameters

Initial value of the N-1 samples preceeding simulation start time. The value must be a scalar or a vector of the same size as the input signal.

Parallel To Serial Conversion

Time between consecutive block executions. During execution, the block produces outputs and, if appropriate, updates its internal state. For more information, see What Is Sample Time? (Simulink) and Specify Sample Time (Simulink).

For inherited discrete-time, specify -1. For discrete-time, specify a positive integer. For continuous-time, specify 0.
