This section covers what is meter tampering, why is this a problem for utility providers, and some common ways a meter is tampered.
This training series looks at High Availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP), which are fundamental to many of the tightly-synchronized, high-reliability systems being built today. HSR and PRP work together or separate to keep systems working even when things break so that power stays on and things keep getting built. Both of them work in the low levels of the Ethernet stack to provide the applications that they serve these fundamental capabilities.
This section contains task-specific videos that demonstrate how to perform debugging techniques on embedded Linux systems.
As the entrance of search engine, the explosive growth in wireless speaker or AI speaker is driving the new requirements of audio amplifier - higher efficiency and better audio quality.
Facing these new challenges, TAS5825M (closed loop classD with 38W stereo output) develops a lot of advanced features compared with traditional audio amplifier, which includes:
As processing requirements for electricity meters gradually increase, it becomes increasingly difficult to find one device that meets both the processing requirements for adding advanced metrology features to smart meters while also accurately sensing metrology parameters, such as RMS voltage, RMS current, and active power. To deal with this design challenge, one option is to use a separate metrology microcontroller and a standalone ADC.

Learn about how to overcome high frequency challenges using TI's series capacitor buck converter.
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.
This 7 Part Series with the MSP430 5xx Experimenters Board will cover the following topics:
- Active and low power mode operation
- Mixed signal application example
- Hardware timers to conserve power
- Implementing a fully optimized ADC12 routine
- MSP430 tools, resources, and conclusions
This training presents TI’s ready-to-use EtherCAT masters solutions for Sitara processors. EtherCAT master on Sitara runs on different operating systems, including TI-RTOS and RT Linux. It also runs on the EMAC interfaces (CPSW and PRU ICSS_EMAC) of any Sitara device, including AM57x, AM437x, and AM335x.
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.
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.
