    What you need to connect a SensorTag to the Amazon AWS cloud via a mobile app

    In most Internet of Things (IoT) use cases there is a need to send sensor data to an IoT cloud solution. Data sent and stored in an IoT cloud solution can then be analyzed and utilized for a number of different purposes. For example, the SimpleLink™ multi-standard CC2650 SensorTag kit using Bluetooth ® low energy can easily be connected to a mobile phone app, with the phone acting as a gateway for passing sensor...

    LaunchPad™ kit meets dual-band connectivity

    We recently announced the SimpleLink™ dual-band CC1350 wireless microcontroller (MCU) supporting Sub-1 GHz and Bluetooth ® low energy on the same chip. It is the first dual-band SoC in mass production to support a wide range of use cases combining long-range, low-power Sub-1 GHz communication with local and ubiquitous Bluetooth low energy connectivity. This means that the CC1350 wireless MCU can communicate...

    Using OpenCLTM to offload to C66x DSPs on Sitara™ AM572x processors

    Customers traditionally approach the programming of complex ARM® + C66x digital signal processor (DSP) systems on chip (SoCs) such as TI’s Sitara™ AM57x SoC by focusing on manually partitioning the application across the ARM cores and DSPs and hand-optimizing the appropriate sections of the application for the given core. This approach tends to yield the maximum entitlement but has drawbacks; –the...

    Tripping Point: Isolation amplifier-based alternating current voltage measurement in protection relays

    Protection relays are used to protect high- or mid- or low-voltage power systems, sense an abnormal condition in the circuit, and command the operation of circuit breakers. Voltage and current inputs from the equipment being protected are connected to the protection relay. Protecting power-system elements requires accurate measurement of three-phase voltages and currents to provide reliable fault detection and breaker...

    Six reasons you shouldn’t pick an MCU

    Choosing a microcontroller (MCU) for your design is not all about the silicon. Sure, most vendors provide a list of all their wonderful features and peripherals, but most don’t talk about the hard stuff – how do you write and debug software for the thing? I remember one vendor bragging about their debug port at a seminar I sat through a few years ago. I was even excited when they talked about all the information...

    Meet the new e-paper Extension Kit Gen 2 by Pervasive Displays

    Pervasive Displays EPD Extension Kit Gen 2 is the perfect way to start developing e-paper-based applications. E-paper technology is great for ultra-low power applications – once text or an image is pushed to the display, no power is required to keep the content on the screen. The EPD Extension Kit Gen 2 supports various e-paper display sizes, ranging from 1.44” to 4.2”. The EPD Extension kit works with...

    How to fix your simulations when the macromodel’s voltage noise doesn’t match the datasheet

    When responding to questions posted on TI E2E™ Community forums , we frequently run simulations using TINA-TI ™ software, a SPICE-based simulation program. Since we are always in the process of updating our simulation models, we sometimes run across SPICE models that are old, outdated or incorrect when modeling performance parameters. One recent example involves the voltage-noise density of the OPA2333...

    Quantifying harmonic distortion: Estimating THD without performing a full FFT operation

    Continued from Part 1 of my blog series on quantifying harmonic distortion. As a less computationally intensive alternative to calculating each harmonic RMS value for THD, you can estimate THD by calculating the total RMS of the harmonics (excluding the fundamental). First, calculate the RMS of the fundamental and subtract it from the total RMS. Equations 1 through 4 are the resulting THD representations: ...

    Answering the infamous question, “Where is my bus?” with BeagleBone and Amazon Alexa

    Bus signs are great at giving passengers information regarding which bus routes serve their stop, but they fail to help with complicated questions like, "Does bus X pass by stop Y ?" Fortunately, with the advent of voice recognition technology, passengers no longer have to be constrained to the information provided at traditional bus stops. We can now provide all the information a passenger would want through...
