Charles J. Lord, PE is an embedded systems consultant and trainer with over 40 years' experience in system design and development in medical, military, and industrial applications. For the last twelve years, he has specialized in the integration of communication protocols into clients' products, including USB, Ethernet, and low-power wireless including ZigBee, 6LoWPAN, LoRa, and Thread. He has taught classes in these protocols for Freescale, Renesas, various universities and conferences including ESC and Arm TechCon. He has been a design partner with Freescale/NXP, Microchip, and Renesas. He also teaches webinars for various clients on IoT and embedded systems topics. He earned his BS in electrical engineering from N.C. State University in Raleigh, N.C. and provides training and consulting services through his company, Blue Ridge Advanced Design, in Asheville, N.C. He is a licensed professional engineer in NC and a senior member of the IEEE. In his volunteer work at the IEEE, he has served at many levels from local to regional to board committees. He is currently the chair of the IEEE Western NC Section, NC Council and was general chair of IEEE SoutheastCon 1995 and 2017.

February 26 - Day 5: Troubleshooting Our RTOS Design

Now that our code is written, we will need to test and debug it. In this final class, we will see how the debugger works with the RTOS to provide task-level debugging. The finished code will be available to help course students follow along and compare with their own code.

February 25 - Day 4: Defining and Running the Project

In this penultimate class, we will take what we learned so far and define the tasks of our project. We will look at some simple "lightweight" elements that we may choose for our project, such as messaging, events, semaphores, and mutexes.

February 24 - Day 3: Changing Processors & Making It Work

A common challenge of RTOS implementations is their limitation to certain chips, development boards, and toolchains. We will bring up our initial solution using the STM32F100 board and then look at how we will have to modify the code to work with our designated STM32 Nucleo processor and board.

February 23 - Day 2: RTOS System Development Setup

Our toolset will be an important part of making our project successful. We will install and investigate these tools, followed by learning how to set them up, consisting of the STMicro STM32 Nucleo and the Atollic TrueStudio IDE, in tandem with the freeRTOS download.

February 22 - Day 1: Introduction to freeRTOS / RTOS Refresher

In this leadoff class, we will review the basics of how a task-switching RTOS operates and the design criteria we need to begin our hands-on design project. We will look at the freeRTOS real-time operating system and the elements that we will be using in our project.

December 4 - Day 5: Running and Troubleshooting Our RTOS Design

Now that our code is written, we will need to test and debug it. In this final class, we will see how the debugger works with the RTOS to provide task-level debugging to help us debug and make the application work. The finished code will be available to help course students follow along and compare...

December 3 - Day 4: Reviewing and Writing Our Tasks

In this penultimate class, we will take what we learned so far and define the tasks of our simple project. We will look at some simple "lightweight" elements that we may choose for our project, such as messaging, events, semaphores, and mutexes.

December 2 - Day 3: Writing Our Board Support Package

One of the biggest drawbacks to "free" software is the lack of hands-on support for customization. Although you can buy support to assist in the creation of your board definitions (I/O, clocking, etc), there is good documentation to help us in this task. In this class, we will first define our...

December 1 - Day 2: RTOS System Development Setup

Our toolset will be an important part of making our project successful. We will investigate the tools that we will be using and how to install and set them up. Our toolkit will consist of the Kinetis Development System, Kinetis SDK (software development kit), and, of course, the MQX RTOS. All three...

November 30 - Day 1: Introduction to MQX and RTOS Refresher

In this leadoff class, we will review the basics of how a task-switching RTOS operates and the design criteria we need to begin our project. We will look at the Freescale MQX real-time operating system and the elements that we will be using in our project.
