Summary

This article discusses the new library structure that was released with ModusToolbox 2.2.  I explain it by showing the creation of a template project that use FreeRTOS and NT Shell.

Story

I have often started projects from the IoT Expert FreeRTOS template project.   I realized the other day that almost always the first thing I do after creating the project is add the NT Shell library.  My friend Hassane has a personal mantra that if he is going to do the same job more than once he will always automate it.  I should have listened to him on this one because I have done it a bunch of times.

In Modus Toolbox 2.2 we have created a new library scheme which allows sharing of libraries between projects.  So this will also be a good example of how that works.

This will also give you another example of adding template projects to your own manifest.

Here is what I am going to do:

  1. Create a project from the IoT Expert FreeRTOS Template
  2. Add the NTShell Library & Examine New Library Structure
  3. Update the Project and Program
  4. Add the Task List functionality (a nice feature of FreeRTOS)
  5. Put the new template on GitHub
  6. Update the IoT Expert App Manifest
  7. Test the new Template

Create & Test a project from the IoT Expert FreeRTOS Template

I will start the whole process by creating  new project using my existing base template.  The kit that I happen to have on my desk right now is the CY8CKIT-062S2-43012.

Select the IoT Expert FreeRTOS Template and give it a name.  Notice that I add “NTShell” to the name (because that is what Im gonna add)

When you click create, Modus will do its magic and build you a complete project.

Today Im going to edit using Visual Studio Code.  Actually almost always I edit using Visual Studio Code.  You can do all of these tasks using Eclipse as well.  To turn my created project into a VSCODE project run “make vscode”

Before getting to far down the road I like to run a build to make sure everything is OK.  So “make -j build”

Add the NTShell Library & Examine New Library Structure

Everything is working and my basic project has FreeRTOS and a blinking LED.  Now let’s add the NT Shell Library.  To do this run the library manager by running “make modlibs” (or click on the button in Eclipse).  Select Libraries –> IoT Expert –> ntshell

When you press update, the library manager will do its thing again.

When I look in the “deps” directory, I see some new file types called “.mtb”.  These files tell your project where to find each of the libraries.  Notice that the middleware-ntshell.mtb points to “$$ASSET_REPO$$”.  Where is that?

If you have a aook at the Makefile it tell you that it is “../” and “mtb_shared”.

# Relative path to the shared repo location.
#
# All .mtb files have the format, <URI><COMMIT><LOCATION>. If the <LOCATION> field 
# begins with $$ASSET_REPO$$, then the repo is deposited in the path specified by 
# the CY_GETLIBS_SHARED_PATH variable. The default location is one directory level 
# above the current app directory.
# This is used with CY_GETLIBS_SHARED_NAME variable, which specifies the directory name.
CY_GETLIBS_SHARED_PATH=../
# Directory name of the shared repo location.
#
CY_GETLIBS_SHARED_NAME=mtb_shared

To start editing I will run Visual Studio Code by typing “code .”.  The first thing that happens is that it notices that this is a workspace instead of just a directory.

And when you look at the workspace you can see that it knows about both the example project as well as “mtb_shared”.  That is sweet.

Update the Project and Program

Now follow the instructions from the middlware-ntshell readme by copying “usrcmd.*” into my project.

arh (master) IoT_Expert_FreeRTOS_NTShell_Template $ cp ../mtb_shared/middleware-ntshell/latest-v2.X/template/psoc6sdk/usrcmd.* .

Then I edit main.c to

  1. #include “usrcmd.h” on line 8
  2. Start the shell task which is called “usrcmd_task” on line 39

Now buid/project by running “make -j program”

arh (master *) IoT_Expert_FreeRTOS_NTShell_Template $

Now I have a functional shell.  Here is the serial console.

Add the Task List functionality

In the main.c above I started up the usrcmd_task with a stack size of config_MINIMAL_STACK_SIZE * 4.  Where did I get that?  Well the first couple of times I did this it crashed by running out of stack so I tried bigger and bigger numbers until it stopped crashing.  This is a kind of a pain in the ass.   If you know FreeRTOS there is a function called “vTaskList” which will give you stats about the tasks.

In order to use that function you need to turn it on.  Notice that I #ifdef and #if to see if it is turned on inside of usrcmd.c

#ifdef configUSE_TRACE_FACILITY
#if configUSE_STATS_FORMATTING_FUNCTIONS ==1
static int usrcmd_list(int argc, char **argv);
#endif
#endif

So let’s turn it on by editing “FreeRTOSConfig.h” and enabling the two required defines.

#define configUSE_TRACE_FACILITY					1
#define configUSE_STATS_FORMATTING_FUNCTIONS        1

Now build/program.

Put the Template on GitHub

I am happy with my new template.  So, I go to GitHub and create a new repository.

Then on my current project:

  1. I blow away the git history (didnt really have to do that).
  2. Create a new git repo “git init .”
  3. Add a pointer to GitHub “git remote add….”
  4. Add all of the files “git add *”
  5. Add the .gitignore “git add .gitignore”
  6. Commit the changes “git commit…”
  7. Push it to GitHub “git push …”

Update the Manifests

To get access to the new template I need to add it to the IoT Expert App Manifest.  I edit the xml file to have the new app

Everything should be working so make a new project.

Cool.  There is the new template.

When I program it… everything is cool.
