LC-sensing solution with TI FemtoFET and CC1350 Sensor Controller Engine

Inductive sensing with TI FemtoFET and CC1350 Wireless MCU

Water and heat meters share multiple system building blocks, such as the metrology sub-system and the application sub-systems, the Wireless communications part, the InfraRed optical port or the power solution. In this section, we will cover a new ultra-low cost single-chip LC-sensing solution utilizing the CC1350 Wireless MCU and its Sensor Controller Engine. Two external LC-tanks with a TI FemtoFET device each implement two rotation detection sensors, which measure the rotation of a half-metal/half-nonmetal disc, often used in mechanical water meters.

Bidirectional InfraRed PHY communication with a single IR LED

Some EU standards like EN1434-3 for heat meters require optical interface as per EN62056-21, where two separate IR LEDs are used (one for receive and one for transmit direction). TIDA-01212 shows an alternative approach, which uses a single IR LED to implement a bi-directional IrDA PHY link with 9.6 kbps in half-duplex mode. The design approach can  the system reduce cost of any smart (sub-)metering device by replacing the legacy optical IrDA PHY modules with two separate LEDs.

This section frames the design and operation video series by showing why it is important to contextualize customer problems in terms of the links between the devices. 

Specifically, this section will discuss: issues with initializing the camera and issues with reading the incorrect serializer ID from the deserializer.

DS90UB953/954 System Design & Operation: Basic Design Rules

Understanding what hardware and software settings are important is critical to establishing a foundation for the 953/954 system. These settings can occur during or after power up and may need to be changed via software. As a result, these settings are routinely checked and verified before checking any of the other links in the system.

Specifically, this sections discusses: Diagnostics post power up, Mode and IDX Pins, Clocking Modes between the 953/954, Aliasing, I2C Pass Through, Port selection on 954, Analog Launch Pad (ALP), and Successful I2C Communication

DS90UB953/954 System Design & Operation: 953-954 Link Design

This section analyzes the link between the 953 and 954 and establishes how to identify the health and operation of the link. Since the link between the 953-954 is the most fundamental link used to communicate between devices, it is often checked first.

Specifically, this section discusses: Back Channel configuration, Built in Self Test (BIST), Adaptive Equalization (AEQ), and Channel Monitor Loop (CMLOUT)

DS90UB953/954 System Design & Operation: Sensor-953 Link Design

This is the Sensor and 953 Link Design section in DS90UB953/954 System Design & Operation video series. This video discusses how to use the sensor-953 link, as well as, the specific settings that are used with this link.

DS90UB953/954 System Design & Operation: 954-ISP/SoC Link Design

This section discusses what frame synchronization (FrameSync) is and how to configure in on the 953 and 954 and how CSI2 data is transferred across the link from the 954 to the ISP/SoC

Specifically, this section discusses: Frame Synchronization (FrameSync), Controlling 953 GPIOs locally and remotely via I2C, Unsynchronized and synchronized sensors, Internal and External Frame Sync, Port Forwarding, Accessing Indirect Registers, and Pattern Generation on 953 & 954

DS90UB953/954 System Design & Operation: Hardware Design

This section discusses how design a 953/954 using Power over Coax (PoC), and various hardware checks and concepts that need to be considered when analyzing a 953/954 system.

Specifically, this section discusses: Power Over Coax (PoC), AC Coupling Capacitors, PoC Inductors, Typical PoC Schematic, Critical Signal Routing, I2C Pullups, Loop Filter Capacitors on 953, Insertion Loss, Return Loss, and Time Domain Reflection (TDR) measurements.

Isolation in Industrial Systems

In 2019 more than 2.5 million industrial robots will be in operation worldwide, according to a forecast of the international federation of robotics. An industrial robot typically consists out of a control cabinet, a robot arm and a Human Machine Interface (HMI) Panel. To guarantee safe operation of the complete robot system, the different robot components and its interfaces need to be isolated to each other.

How to add Industrial Ethernet to Computer Numeric Control (CNC) Router Machine

CNC routers use step and direction signals to control each stepper motors. In addition motor information (position, temperature, fault) gets transferred from stepper motors back to control unit. This must be done in star topology and a mix of proprietary interfaces. Simple open real-time Ethernet (SORTE) enables 4 µs cycle time on industrial Ethernet and replaces step/direction signal and motor feedback info into a single Ethernet cable that is also wired in line topology.

Learn Different Solutions to Design a Field Transmitter Ultrasonic AFE

A common method to measure process parameters in plants is based on sound waves. This method is used in: level, flow and displacement field transmitters. It works based on measuring the time of flight (ToF) between when the pulse, generated by a piezo electric crystal, is sent and received back by the piezo.

Low EMI and Noise performance with DC/DC switching regulators

Concepts of Switching Regulator EMI and Noise Mitigation

Before we dive into specific application-based examples of noise and EMI mitigation, let's start with the basics. What is noise? What is EMI? What is ripple? How are they measured? What are some common approaches to limiting their effects? This section discusses these topics with a more conceptual approach to serve as a primer for the rest of the series.
