The Control Law Accelerator is a 32-bit floating point math accelerator that is common on most c2000 devices. It aids in the concurrent processing of fast control algorithms.
After viewing the lectures, and working through the provided example, you should be in a better position to migrate existing algorithms from the main C28x core to the CLA, or start programming on the CLA from scratch.
These videos introduce the C2000 TMS320F28004x family of devices.
This collection provides access hands-on exercises and training materials from technical workshops across a variety of C2000 devices:
- F28004x microcontrollers
- F2837xD microcontrollers
- F2806x microcontrollers
- F2803x microcontrollers
- F2802x microcontrollers
- F2833x microcontrollers
- F280x microcontrollers
- F281x microcontrollers
- F28M35x microcontrollers
- LF240x microcontrollers
The first line of defense against tampering by bypassing current, reversing connections, and disconnecting leads is the meter case. Due to this, it is common for utilities to require some form of intrusion detection system to detect when someone opens a case. In this section, we will cover how to detect someone trying to open the case of a meter.
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.
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.
In this section, a summary of the entire “Anti-tamper Techniques to Thwart Attacks on Smart Meters” training module would be covered. This summary would cover the “Detecting case tamper attacks using inductive switches “, “Detecting magnetic tampering using hall-effect sensors “, and “Hardening a meter against magnetic tamper attacks “ sections of the training series. Links will be provided for the reference designs and design tools that were discussed during this training series.
Explore training modules to gain an understanding of the core attributes of the Piccolo MCU family.
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 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 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.
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.
