This application report provides a brief overview of the Device Firmware Upgrade (DFU) class describes the Stellaris implementation in the USB boot loader (boot_usb) application and also describes the hostside lmdfu dynamic link library for Windows. Use of the standard USB DFU class on Stellaris USBenabled microcontrollers offers a convenient and fast method of replacing main application image

ABT Applications

This document provides implementation instructions for the DDR2 interface contained on the C6457/TCI6484/TCI6487/88 DSP.

This application report describes a buck regulator?s inability to startup when there is a voltage already present at the regulator?s output (VOUT). Although the LM5007 is used in this application rep

Monitoring Fan Tachometers using the UCD908x Devices

The DAC714 is a complete, easy-to-use 16-bit digital to analog converter featuring a voltage output with and a precision reference together with a serial interface.

This design note is a general description of how to set up <b>open field</b> range measurements and what has to be considered. Applies to all low power RF-ICs.

This application note describes a method for developing block-oriented I/O device drivers for applications that use the DSP/BIOS real-time kernel and includes examples that run with Code Composer Studio v2.1 on the Texas Instruments TMS320C5402 and TMS320C6711 DSP Starter Kits (DSKs). The device driver model presented here has now been superceded with an updated version that supports not only bloc

This application report presents a solution to control a permanent magnet synchronous motor (PMSM)using the control law accelerator (CLA) which is a small footprint coprocessor that is present on some ofthe microcontrollers from the C2000™ family of MCU. TMS320F2803x devices are part of the family ofC2000 microcontrollers which enables the cost-effective design of intelligent controllers f

A Walk Along the Signal Path (High-Speed Signal Path)

This application report outlines the implementation of a CPE remote management scheme using the clear EOC Channel. The capabilities of the Clear EOC Channel are discussed for G.dmt different framing mode as well as ADSL2. This application report is meant to be used to provide a basic understanding of the Clear EOC channel and how it might be used for ADSL CPE remote management.

The inter-integrated circuit (I2C) is a multi-master multi-slave single-ended bus that is typically used forattaching lower speed peripheral ICs to processors and microcontrollers. The type of slave devices range from non-volatile memory to data-acquisition devices like analog-to-digital converters (ADC) sensors and so forth. This application report demonstrates how to use the feature rich I

With ever increasing speeds of DSP devices such as the 'C5x and the increasing demand for reduced form factors as in HDD applications there is a need for integrating the program memory into the DSP device. For volume production where the program code has been fully debugged and changes are not foreseen then masked ROM is appropriate. However for prototyping and preproduction evaluation a p

Negative Buck Switching Regulator (using LM258x)

The switch-mode power supply primary current is often sensed using a power resistor. Using an op amp to amplify the current-sense signal can reduce cost and improve noise performance and efficiency. T

This application note discusses the operation and compensation of linear regulators.

This application report reviews several different types of bridge sensors including characteristics of each type and discusses the key parameters of delta-sigma (ΔΣ) analog-to-digital converters (ADCs) at the system level. Additionally the parameters of a ΔΣ ADC are considered for use in common bridge sensor applications

This application report explains the implementation of an Attitude and Heading Reference System (AHRS) using the ultra-low-power MSP430F5xx microcontroller a magnetometer a gyroscope and an accelerometer on all three axes. The calibration of the sensors is key to the accuracy of the algorithm therefore the sensors’ output must be calibrated before being input to the Direction Cosine Matrix (
