STM32 Summit: STM32CubeIDE Makes a Massive Appearance in China

Releasing just these solutions would already be a groundbreaking announcement as there are no tools currently rivaling this feature set. However, STM32Cube. AI is much more than a simple toolkit, but the reflection of our desire to change the IoT landscape by bringing neural networks to all STM32 developers.

As a result, we are also announcing the release of video tutorialsa unique STM32 Community specializing in machine learning, as well as ST Partners that can offer expertise, tools, and services to help companies take part in this AI revolution. Indeed, people who tend to specialize in the types of embedded systems that use our STM32 MCUs may not be familiar with the latest advances in neural networks.

Similarly, data scientists working on machine learning with nearly unlimited cloud resources may be strangers to the memory and computational constraints of embedded platforms. AI thus bridges the gap by demystifying artificial intelligence and embedded systems.

We show that experts and tools are readily available and that it is easy to leverage the increasing popularity of edge computing to run inferences on our platforms. In other words, STM32Cube. AI proves that neural networks on embedded systems are already here.

The foundational piece of the STM32Cube. People unfamiliar with our ecosystem will enjoy our step-by-step guide explaining how to use it to configure the pin-outs and clock trees of their microcontroller, among others, and generate the header files that will jump-start their application. The code generator will then produce a library that developers can use in the application.

If professionals or even enthusiasts want to start rapidly experimenting with our STM32Cube. One of them uses the onboard microphones to capture audio, pre-processes the signal, and then uses inference to determine if a sound comes from indoor, outdoor, or from the inside of a vehicle.

Similarly, the other example program tracks motion to determine if the user is stationary, walking, running, biking or driving. We already compiled the binaries so users can start using these applications by just dragging and dropping a file onto their system to load the demos. We also offer Hardware Abstraction Layers, drivers, and source codes, among others, so developers can learn from our implementations and start writing their test software.

AI combines all these papers and findings in a solution that widens the scope of what was previously possible by allowing the conversion of a large number of topologies onto our platforms for many different applications. While the new tools implement an artificial neural network, we want to distinguish the fact that we also bring machine learning capabilities to a motion sensor that has scarcer resources by using a decision tree. Machine learning, in its broadest sense, uses mathematical models to process data and estimate the best result or decision.

A decision tree is a classifier model in machine learning that repeatedly parses the feature-space into a series of pathways branches and runs through them until the system reaches an endpoint a leafwhich represents a class or decision. Applications can then use the resulting model to infer and estimate the most appropriate response. The decision-making process within the neural network is not as evident and it could require, in some use cases, more resources than a decision tree, but it can process a much larger stream of data to offer more accurate results in a wider variety of applications.

The performance and accuracy of an application that relies on a neural network comes from the right analysis of the type and quality of the data that must be collected and is tightly coupled with the selection of the appropriate network topology.

This is even truer when we talk about deeply embedded solutions. As a result, we ensured that our Partner Program would include companies that can bring the necessary expertise to guide our customers in this process. Others, like SIANA Systemsoffer a more extensive experience for medical, industrial, home automation, and wearable applications. Regardless, these partners will enable STM32 developers to move out of the limitations of our application examples and train neural network models to a level compatible with new commercial products.

Our partners will also assist companies in choosing the right topology. A topology is a representation of the interconnections between the neurons of a network that shows how they interact with the input, influence one another, and get to one or more outputs.

The simplest topology the Multi-Layer Perceptron adds multiple inputs and offers an output with a full range of connections, while a more common topology today, such as a Convolutional Neural Networks, uses a series of inputs interconnected to a set of heterogeneous filtering neurons that offer an increasingly probable output.

Today, data scientists continue to improve and optimize these topologies, but the basic principles remain the same. For instance, audio applications traditionally used a Gated Recurrent Unit GRU that relies on neurons that have a memory capable of recalling previous information.

The beauty of the STM32Cube. Furthermore, these solutions help them improve their productivity since they no longer need to code time-consuming libraries as STM32CubeMX just generates them. Our initiative will thus continue to receive updates to make it easier to use and available to more developers. The code generator includes a selection tool that analyzes the complexity of the network to recommend an STM32 with the right amount of computational throughput and memory.

However, we are working on updating our tools to support fixed-point implementation, which will end up bringing neural networks to even lower-power systems or accelerate inference on our more powerful microcontrollers. AI toolkit even more comprehensive.The announcement is highly symbolic as it first means that developers will, over time, leave SW4STM32 and TrueStudio for the new solution and we already offer migration tools to help them transition.

A standalone version of CubeMX will still be available for those who use a different IDE and we are announcing that both versions will use the same code base, offer the same features, and receive updates at the same time. We are currently offering a version for Windows, macOS, and Linux. Indeed, terms like machine learning, deep learning, and neural networks are now common, but not many fully realize that they need to adopt these technologies now if they are hoping to capture the growing flock of customers that are already clamoring for these features and counting on companies to offer smarter products.

The STM32 Summit will thus be a tremendous opportunity to talk to our experts and engineers to not only learn about these trends but start implementing them. And since a demo is worth a thousand speeches, we will have numerous application examples on the show floor.

The Summit itself will hold more than 20 demo counters on the first day and 68 demos on the second, showcasing a tremendous range of products, applications, and partners with an emphasis on artificial intelligence, cloud computing, and industrial applications.

We will delve deeper into these two other topics in subsequent blog posts but wanted to first address artificial intelligence by going over some of the demonstrations from our teams and our partners, to help attendees understand the new milestone that the industry recently crossed: AI on embedded systems. Engineers no longer need supercomputers to run pre-trained neural networks and an STM32 microcontroller can perform tasks that required server-class components a few years ago thanks to groundbreaking optimizations.

Launched at the beginning of the year, it continues to be the only tool of its kind with such a breadth of features. Similarly, we will showcase tools that use machine learning to recognize human activities running, walking, etc. All these programs will run on STM32 MCUs and prove that embedded systems have a special place in the world of artificial intelligence.

We will also showcase other demos that will highlight the power of our recent MCUs. Additionally, voice recognition is even more crucial because of the popularity of smart speakers. This example also shows how AI can integrate smart applications. Wearables, smart locks, smart thermostats, and other such devices also use machine learning to anticipate their needs better. The adoption of our solutions by partners is the greatest testament to the power and pragmatism of our solutions.

It then uses AI to recognize activities and inform athletes on their performance to help them improve their form or lifestyle. There are also potential medical applications such as assisting patients with their physiotherapy. By relying on our solutions, the company was able to create open frameworks to ensure that their customers can build pertinent applications and distinguish themselves from the competition.

Among the myriad of other partners that will showcase their products and technologies, we will have two Chinese collaborators that will highlight their work in AI. The first one is Open AI Laban organization that will use the STM32 Summit to present their research and development in the field of voice applications.

The second company is Mobvoiwhich uses our STM32F4 microcontrollers in wearables to offer advanced Chinese speech recognition and artificial intelligence to augment what customers can do with their device. For instance, the watch provides a more intuitive interface to help users launch applications, and it also offers smart notifications. AI is already shaping the Chinese market at a pace that may be faster than the rest of the world. Customers are demanding more intelligence and the integration of smarter features in their smart lock, smart lights, smart speakers, smartwatches, and smartphones, among others, which leads companies to jump on the bandwagon quickly.

And ST has such a unique position in this field because we offer the hardware necessary to gather more information as well as the libraries to process those data and the MCUs to run the essential models and inference.

Additionally, because we are already in connected devices, engineers can reuse the tools they know to bring these crucial new features to their designs.Local Predictive Maintenance is one of the topic of this early Local Predictive Maintenance applications are essential to avoid clogging Internet communication lines.

We want to be very clear, many people present this application as simple, is not true, because is necessary several steps and therefore time and resources to devote, before arriving at a real application.

Abstraction is an essential property of software: the app you are using to view this piece is an abstraction layer above some operating system that knows how to read files, display images, etc.

Our reduction is achieved by using tflearna layer above tensorflowa layer above a Python. Each mathematical operation within the model is detailed. The definition of our model is relatively straight-forward, albeit laborious, most of the code is applied to training:.

This worked quite well — we then abstracted it using a framework. This simplified our code same underlying mathematical structuresfor example the handling of Gradient Descent and loss function is conveniently reduced to 2 lines of code. Still unsatisfied with the amount of code and complexity involved, we abstract again using tflearnwhich describes itself as:. So we have our 7 lines of code for a multi-layer neural net. Our notebook code is here. Make sure you have tensorflow 1. It may be helpful on Linux with pip to use:.
