These are a few notes useful if you want to create a new block in Scicos and the corresponding implementation function in ERIKA Enterprise.

Scicoslab 4.4b7

This section describes how to create a new block for Erika Enterprise, and applies the Scicoslab 4.4b7 version of the toolbox.

Installation steps:

  1. Install Scicoslab 4.4b7
  2. Install the last ScicosLab Pack for FLEX boards
  3. Install Microsoft Visual Studio Express 2008 (free version is available!)
  4. Install Erika Enterprise 1.5.1

Block creation tutorial:

  1. Preface: directory names are the directory names of my laptop...
  2. In the folder of interest (e.g. C:\Programmi\scilab\scicoslab_44b7\contrib\dspic\macros\flex_blocks\FLEX-MTB) write the sci code of your block. Please note the name of your C function must be specified in the scicos_model.sim field.
  3. To compile bblck code change the working directory from the scilab console in this way "cd c:/Programmi/scilab-4.1.2/contrib/dspic" and then digit the following command "exec builder.sce". You obtain a .bin file.
  4. To create the new palette file digit the following command "create_palette(folder_path)" (e.g. create_palette("C:\Programmi\scilab\scicoslab_44b7\contrib\dspic\macros\flex_blocks\FLEX-MTB")). You obtain a .cosf file.
  5. Move the .cosf file in the palettes folder (e.g. C:\Programmi\scilab\scicoslab_44b7\contrib\dspic\macros\palettes) replacing older file.
  6. Modify the file named "symbols" inserting the name of your block and the symbols you want to be associated.
  7. Write your C files and place them in the scicos folders inside Erika Enterprise tree. (e.g. C:\Evidence\eclipse\plugins\com.eu.evidence.ee_1.5.1.201005181137\ee_base\contrib\scicos\inc\pic30\mycode.h C:\Evidence\eclipse\plugins\com.eu.evidence.ee_1.5.1.201005181137\ee_base\contrib\scicos\src\pic30\mycode.c). Please check if you must modify the contrib\scicos\cfg\cfg.mk to tell the compiler that your file must be compiled!
  8. Create a scicos diagram and try to genereate the code.

If your application works fine you have successfully completed this tutorial. Congratulations!!! ;-)

Scilab 4.1.2

This information derives from a post in the ERIKA Forum, and applies the Scilab 4.1.2 version of the toolbox.

  1. Preface
    1. Directory names are the directory names of my laptop...
    2. Use the zip file attached. for each step, there are a few files to look at
    3. I had to edit the post to substitute backslash with slashes
  2. Install Scilab 4.1.2
  3. Install the Scicos Pack for the FLEX boards
  4. Install Microsoft Visual Studio Express 2008
  5. Install these patches in Scilab 4.1.2. They are needed to let Scilab discover the Visual studio compiler
  6. NMake
    1. install NMake from http://support.microsoft.com/default.aspx?scid=kb;en-us;Q132084
    2. rename the executable file in nmake.exe and copy it into C:/Windows
  7. Update the files
    1. You need to create the block file. You can use Roberto's block editor http://web.dti.supsi.ch/~bucher/ . Or check out the block example at http://www.evidence.eu.com/component/option,com_fireboard/Itemid,262/func,view/id,6/catid,3/
    2. add into the C:/Programmi/scilab-4.1.2/contrib/dspic/macros/name one line with the file name
    3. in C:/Programmi/scilab-4.1.2/contrib/dspic/bulder.sce , we have to comment a few lines, because we are not going to compile the .c files distributed with the package. in particular, comment from the line "cd(ROUTINES)" to the one but last line (leave only the "cd('..')"
  8. Compile
    1. open scilab 4.1.2
    2. from the scilab console, "cd c:/Programmi/scilab-4.1.2/contrib/dspic"
    3. from the scilab console, "exec builder.sce"
  9. you get an output similar to the following one
    --------------------------------------------------------------------
    ___________________________________________
    scilab-4.1.1
    Copyright (c) 1989-2007
    Consortium Scilab (INRIA, ENPC)
    ___________________________________________
    Startup execution:
    loading initial environment
    shared archive loaded
    _link_ done
    Scicos-FLEX Ready
    -->cd c:/Programmi/scilab-4.1.1/contrib/dspic
    ans =
    c:/Programmi/scilab-4.1.1/contrib/dspic
    -->exec builder.sce
    -->mode(-1);
    -->
    --------------------------------------------------------------------
  10. Add the block to the scicos Palette
    1. "cd macros"
    2. open scicos by typing "scicos();"
    3. Menu "Diagram/Load", load the file "dspic.cosf"
    4. Menu "Edit/Add New block", specify the file name "dspic_getfreq", press ok and place the block inside the palette where you want
    5. menu "Diagram/Save As", and give the name "dspic.cosf" - with the final "f"!!!
    6. close Scicos and Scilab
    7. now if you open again scicos, the dspic palette should have the dspic_getfreq block.
  11. Configuring Erika Enterprise
    1. copy the getfreq.c file inside "C:/Programmi/Evidence/ee/contrib/scicos/src/pic30"
    2. add getfreq.c inside "C:/Programmi/Evidence/ee/contrib/scicos/cfg/cfg.mk" (see file attached for an example)
  12. Create a scicos example
    1. Follow the Scicos tutorial, but use the getfreq instead of the Sine (see files in the zip)
    2. compile and enjoy!
