STM32 Devcoons Framework – Add a module (2)


The flow to add a module in the STM32 Devcoons Framework is a straightforward and seamless process which ease up the development. In this post, we will see the basic rules we have to follow and show a quick example.

1. Place the modules in the corresponding folder
Any module should be placed in the corresponding folder under the /BaseCode/.  

All the modules start with either drv or lib prefix indicating the proper subfolder that they need to reside. For example, the module drv-canbus should be added as a git submodule in the /BaseCode/Drivers/ as well as the module lib-crypto should be added under the /BaseCode/Libraries/ path. Take a look of the following screenshot which explains better this convention.

2. Add a module

1. Using the github url, add the submodule under the correct folder using the following command.

git submodule add <url> <folder_name>

A good tactic is to use a folder name similar to the module name for example:

> git submodule add drv-flash

Le’ts try to do this with the lib-crypto, As a first step, we need to add the library (as a git submodule) into our project. Due to the fact that this is a ‘library’ we should add in under the folder /BaseCode/Libraries/ like the screenshot below.

To add this module, we navigate to the /BaseCode/Libraries/ and we run the following command in the terminal:

git submodule add lib-crypto
3. Include the path in the ‘GCC Include Paths’

TO ensure that the GCC is able to identify the module, you have to include it in the MCU GCC Compiler > Include paths as presented in the screenshot below:

Resuming the example with the lib-crypto, we will add the path in the GCC compiler include paths as presented below:

That’s all! Now you can freely use the module in your code!

Each module may require some extra steps, for example the put a configuration file to enable some features etc. Please always check if there are any .template or .example files
