RTOS Design and Debugging Techniques Hands-on

Instructor(s): Jacob Beningo

When: 05/18/2021 15:00:00 (EST)

Duration: 2 hours

Real-time operating systems (RTOS) have found their way into nearly every embedded system. The problem though is that an RTOS can often complicate implementation, increase module coupling and make debugging a nightmare.

In this workshop, Jacob Beningo will walk attendees through RTOS implementation and debugging techniques that will help developers accelerate their design cycle and implement more robust and flexible design techniques. Attendees will learn hands-on about topics such as:

  • How to initialize tasks
  • How to properly set task stack size and monitor for stack overflows
  • Decouple application code from the RTOS
  • Properly protect shared resources
  • Minimize response time for system events
  • Perform application tracing and performance analysis

Additional topics and details about specifics boards and RTOS will be provided closer to the conference.

Test-Driven Development

Instructor(s): James Grenning

When: 05/18/2021 13:00:00 (EST)

Duration: 2 hours

Test-Driven Development is a technical practice that supports Agile's iterative and incremental development cycle. TDD helps you quickly discover mistakes, preventing defects. You weave a test safety net as you grow your product's behavior one test at a time. This safety net supports you now and in the future to help you keep code working as you change it. Oh yeah, don't let me forget to tell you it's fun and once you learn it, you save time and money.

Maybe you have heard of Test-Driven Development but don't quite get it. A good way to understand TDD is to pair program with an experienced practitioner. We will start with a brief overview and demo of Test-Driven Development. In this interactive workshop, you can practice TDD in C. You don't need to install any tools for this workshop. You'll run the exercise on my exercise server. You will know what TDD is after this session. We'll conclude the workshop with a debrief on your experience.

Before attending this workshop, it is highly recommended that you watch this talk from the 2020 Embedded Online Conference.

Notebook: Fast Track FIR Filter Workshop.ipynb


Finite Impulse Response (FIR) filters are the more popular of the two main types of digital filter implementations used in DSP applications. In this workshop, we will go through best practice approaches for optimized FIR filter design and implementation using the free and open-source Python programming language. This will include the common techniques for going from filter requirements to practical implementation and demonstrate both creating FIR filter designs as well as evaluating filter frequency responses using the Python language and its signal processing library.

This workshop will include:

  • Complete setup to get Python up and running for signal processing applications.
  • Summary of the high-level approaches to FIR filter design – which are best and why?
  • Fast track to using the signal processing library in Python for creating FIR designs.
  • The complete design flow for FIR filters from specification through verification.
  • Using Python for filter evaluation, including plotting magnitude and phase responses.

Training and Deploying ML models to STM32 Microcontrollers

Instructor(s): Jacob Beningo

When: 10/07/2021 10:00:00 (EST)

Machine learning (ML) has often been considered a technology that operates on high-end servers and doesn’t have a place in traditional embedded systems. That perception is quickly changing. This workshop will explore how embedded software engineers can get started with machine learning for microcontroller based systems.

This session balances theory with practical hands-on experience using an STM32 development board.

Attendees will learn:

  • How to collect and classify data
  • Methods available to embedded developers to train a model
  • Hands-on experience training a model
  • How to convert a model to run on an STM32 MCU
  • How to run an inference on a microcontroller

  3. Check out this github link for more workshop material, including a pdf of the slides: https://github.com/AdiuvoEngineering/EOC_DSP

Developing programmable logic solutions is moving up the levels of abstraction.

In this session we will use the Arty Z7 board and the Xilinx PYNQ framework to accelerate signal processing algorithms (FFT, FIR Filters) in programmable logic using with a combination of Python and High-Level Synthesis (C/C++). Techniques such as this will allow us to leverage the processing capabilities of programmable logic without the requirement to develop solutions using traditional FPGA Register Transfer Languages. This enables smaller, more power-efficient solutions.

This session will introduce the PYNQ framework and explain how it interacts with the programmable logic. We will then explore how we can use HLS – what is it, how do we go from untimed C to logic gates and what optimisations do we need. Finally, we will look at how we can build PYNQ overlays using IP Integrator which can be loaded onto the Arty Z7 for use with our Python application using Jupyter Notebooks / Labs.
