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.

June 10 - Day 5: Advanced Coding

Now that we have written some code and started testing out our node, we will learn some advanced application programming and alternative means of programming our nodes. In this final class, we will see how to make use of the chip I/O as well as how to load the chip with Arduino for use with the...

June 9 - Day 4: The NodeMCU in Depth and Programming

In this penultimate class, we will take what we learned so far and write some beginning code on the ESP8266. We will learn how to configure a node to work with a specific network then look at ways that we can use the node in our local Internet of Things.

June 8 - Day 3: Lua in Depth, Part 2

For our third class, we will delve into the more advanced aspects of Lua, including nested functions and some of the application-specific features for gaming and other applications.

June 7 - Day 2: Lua in Depth, Part 1

For our second class, we will begin to look at the Lua language in depth. We will look at all of the basic constructs, including variables and program flow, and show some examples of each and how we can test some basic programs as we go along.

June 6 - Day 1: Introduction to Lua and the ESP8266

In this leadoff class, we will look briefly at the ESP8266 chip and the various Node MCU boards that are available with the chip. We will then discuss the history of the Lua language and how it is used for programming various applications.

April 8 - Day 5: Advanced Board Work

Now that our code is verified, we will look at more advanced concepts with the boards including monitoring ('sniffing') traffic and integrating security. We will then look at changes of topography and the dynamic capabilities of the network to reconfigure and heal itself. We will conclude the class...

April 7 - Day 4: Testing the NXP Boards

In this penultimate class, we will load the stack and sample setup applications on our test boards for testing and verification of basic operation. We will test the basic setup of the network, the commissioning of a node, and data transfer.

April 6 - Day 3: Sizing Up The Thread Stack

The Thread stack consists of many modules including IEEE 802.15.4, 6LowPAN, UDP, Security, Mesh, and the actual application and its protocols. In this class, we will look at the structure of the actual code for the stack and how we will be using it for our hands-on testing in the final two classes.

April 5 - Day 2: Looking at the Thread Protocol, in Depth

We will continue to examine the Tread protocol in depth, including the stack structure, the underlying standards and how they interoperate, and the design principles. We will compare the underlying IEEE 802.15.4 PHY and MAC structure with Bluetooth 4.x and IEEE 802.11 (WiFi).

April 4 - Day 1: Review of Home Automation Protocols

In this leadoff class, we will review history of home automation (HA) protocols, starting with the old standby X-10 protocol and comparing it with the current competing protocols, including ZigBee, RF4CE, Z-Wave, and others. We will compare the strengths and weaknesses of each and examine where...
