Introduction

This section covers wireless network trends, key technologies, and problem statements for smart grid IoT. 

System-Level Examples for Wireless Networks on Smart Grid IoT

This section covers system-level examples for wireless networks on smart grid IoT. We will provide software- and system-level details for two system examples: 6LoWPAN-Contiki and sub-1GHz sensor to cloud industrial IoT gateway reference design. 

Summary

This section summarizes the wireless network challenges and solutions for a smarter grid IoT training series. 

Detecting magnetic tampering using hall-effect sensors

For anti-tampering, it is common to try to detect the presence of a strong magnet. In this section, we will cover the use of hall sensors for low-power detection of strong magnetic fields in three dimensions.  Details on our magnetic tamper detection reference design, TIDA-00839, will be provided as well as some of the design considerations that were kept in mind when creating this reference design.  

Hardening a meter against magnetic tamper attacks

In this section, we will cover how to harden a meter against these magnetic tamper attacks by using shunts for current sensors. For poly-phase implementations, I will go over how to use isolated delta sigma modulators to add the necessary isolation to use shunt current sensors and create magnetically immune poly-phase energy measurement systems. The TIDA-00601 and TIDA-01094 reference designs, which show how to implement a poly-phase isolated shunt measurement system, will be discussed as well as the associated AMC1304 high-side power supplies used in these designs.

Introduction to the CLA

This module covers the architecture of the CLA, the resources at its disposal and the division of code into task blocks that are triggered by peripherals or through software. Each of these task blocks are atomic, in the sense that no other task may interrupt a running task. This makes operation of the CLA unconventional in comparison with standard CPUs.

Control Law Accelerator

The CLA 'C' Compiler

The CLA is supported by a subset of the ANSI ‘C’ Compiler. You will learn the features, and more importantly, the limitations, of this compiler in this video.  The video also covers the changes in the linker command file needed to support operations on the CLA

Control Law Accelerator

The Workshop

In this video we get into the actual workshop. I will take an existing project for the C28x, a simple example that samples an EPWM, runs it through a low pass filter, and then an FFT to get the frequency spectrum, and migrate it over to the CLA. You can download the project files here and I encourage to follow along as I go through the different steps and considerations during the migration process.

Debugging on the CLA

Once you have ported your code over to the CLA and successfully built your executable, it’s time to debug. The CLA pipeline is unprotected and is debugged through the main CPU; you cannot debug code on the CLA in the same manner you would on the C28x. This module goes over the different aspects of setting breakpoints, single stepping and setting up CCS views when debugging the CLA.

Control Law Accelerator

Tips and Tricks

In the previous modules you would have learned the workings of the CLA, the implementation of the ‘C’ language, and its unique method of debugging. This video deals with some of the common issues users face when writing code for the CLA. It is a compilation, and investigation, of some of the most commonly asked questions on the forums and should help you get to working code quickly.

Devices

Explore training modules to gain an understanding of the core attributes of the Piccolo MCU family.

Tools

There are a variety of tools to make development with the Piccolo family easier. These trainings provide an introduction to real-time features and software, as well as more detailed trainings on CLA.

Motor Applications

Motor control functionality is a key attribute of the C2000 family.  Get started with your motor control application on Piccolo MCUs using these trainings which range from introductory overviews to advanced tips for motor control optimization.

Power Applications

Power efficiency is a key requirement for applications today.  These introductory trainings explain how to implement digital control loops by taking an analog compensator and converting it to the digital domain using C2000 MCUs.

Control Applications

For control applications, an understanding the fundamentals of control theory is required.  These trainings provide a foundation for creating control applications and provide some advanced training on the spate space modelling paradigm.

TI-RSLK

TI-RSLK Module 1 Running code on the LaunchPad using CCS

The purpose of this module is to learn software development methodology and understand how to set up an Integrated Development Environment (IDE), to then import and export Code Composer Studio (CCS) projects, as well as critical debugging information to understand the memory usage and performance of the software on the processor.

TI-RSLK

TI-RSLK Module 2 – Voltage, current, and power

The purpose of this course is to review basic electronic components and the electrical properties needed to interface sensors and actuators to a microcontroller. You will learn how to measure reactance of a capacitor and use your project to measure current and voltage. The electrical properties of the capacitor will help you design circuits that “filter” or remove noise from your robot.

TI-RSLK Module 5 – Battery and voltage regulation

The purpose of this module is to learn how to power your robot. To run the robot (motor and other systems) you will need batteries and a regulator to provide constant voltage.  Understanding the relationship between voltage current and power is an essential component of robot system design.
