Using a switching regulator as an LED driver requires the designer to convert a voltage regulator into acurrent regulator. Beyond the challenge of changing the feedback system to control current the LEDsthemselves present a load characteristic that is much different than the digital devices and other loads thatrequire constant voltage. The LED WEBENCH® online design environment predicts and
This application report describes how to build a digital heart-rate monitor using a MSP430FG439 microcontroller (MCU). The heartbeat rate per minute is displayed on an LCD. In addition, the applicatio
Many MSP430-based systems are likely candidates for implementation as finite state machines. A system that must sequence a series of actions or that must handle inputs differently depending on the mode it is in is often best implemented as a finite state machine. Typical examples are control-logic-oriented applications such as metering monitoring and control applications. This application report
ObjectVideo® OnBoard™ is a software product that monitors video feeds for events and alerts you in real-time as events occur. ObjectVideo OnBoard technology performs much of its video analysis on intelligent devices such as DSPs. This document describes how to deploy ObjectVideo OnBoard with the Texas Instruments TMS320DM6437 (DM6437) evaluation module (EVM) which is based on DaVinci&
This application report presents a hardware and software solution to interfacing the ADS8345 16-bit 8-channel 100 kHz analog-to-digital converter to the C5000? fixed point 16-bit family of digital signal processors (DSP). While this application report primarily focuses on the 8-channel ADS8345 part the same solution can be utilized for the 4-channel ADS7841/ADS8341/ADS8343 and 8-channel ADS834
Industrial networks must operate reliably in harsh environments. Electrical over-stress transients caused by electrostatic discharge switching of inductive loads or lightning strikes will corrupt data transmission and damage bus transceivers unless effective measures are taken to diminish transient impact.This article gives an overview of the three most commonly applied transient immunity t
This document describes various techniques that interface buffer op amps to ADCs. These techniques provide designers with a toolkit of ideas that can be readily adapted to their application. Fully differential transformer coupled and single-ended techniques are described. Reference techniques and circuits are also described in Appendix A.
This application report discusses the fundamentals of board level reliability (BLR) (sometimes referred to in literature as “second-level reliability”) testing and modeling as applied by the Texas Instruments Embedded Processing Group.
1-Wire can be used in systems that have low speed and low power communication requirements. This application report describes the 1-Wire communication protocol, available TivaWare™ for C Series
