The OMAP-L137 C6747/6745/6743 devices use a great deal of internal pin multiplexing to allow the most functionality in the smallest and lowest cost package. This software allows the pin multiplexing registers of the device to be calculated with ease as well as showing what peripherals can be used together and what devices support the peripherals that are selected. This software is useful to anyo

AN003 -- SRD Antennas

Asynchronous communication protocols rely on each node operating at the same frequency. Modulating the microcontroller operating frequency is possible when the modulation frequency is large enough. Unfortunately the EMC-reducing aspects of clock modulation are most effective when the modulation frequency is small. This application note defines the minimum modulation frequency in relation to the C

The LM3404/04HV is a buck-regulator designed for driving high powered LEDs at forward currents of upto 1.0A. LED drivers often experience thermal conditions that are extreme even by the standards ofswitching converters. For example LED drivers are often placed on the same metal-core PCB (MCPCB)as the LEDs themselves. At 1.0A a single-die white LED can dissipate more than 3W. The temperatur

Trapezoidal Control of BLDC Motors Using Hall Effect Sensors (DRV8312-EVM)

This EVM application converts an input value with the analog-to-digital converter (ADC) module of the Texas Instruments (TI)(tm) TMS320F240 Evaluation Module (EVM) and outputs a pulse width modulated (PWM) signal corresponding to the digital conversion of the analog input.

This application note provides an indepth discussion of design references for A/D converters.

A stack overflow in an embedded DSP application generally produces a catastrophic software crash due to data corruption lost return addresses or both. Traditional off-line approaches to sizing a stack during development such as filling with a know value or estimating based on code content are not 100% reliable. Therefore programmers often feel compelled to reserve larger stack sizes than are

2.5 Gbps LVDS 4 x 4 Crosspoint Switch

This technical brief provides an overview of communication receiver sensitivity. One of the most important parameters in determining the overall performance of a communication system, receiver sensiti

This application bulletin covers the DDC112’s test mode. It elaborates on the explanation given in the data sheet and is written with the purpose of helping you use the test mode to its fullest capability. It does assume a basic understanding of the DDC112’s operation. For a good introduction to the DDC112, see the DDC112’s data sheet.

The organization of this application bulletin is as follows: First, an overview presents the basic operation of the test mode. Next are explanations of single packet and multiple packet test signals. Noise and linearity performance of the test mode are then covered followed by some special considerations for using the test mode. Finally, a program for investigating test mode performance is discussed with the listing for the program given afterwards.

Switching voltage regulators represented by the TL497 can achieve high-efficiency power conversion at large input/output voltage differentials. The TL497A eliminates complex circuit designs previously required and provides greater efficiency than systems using series pass regulators. The principle of operation is discussed and practical design exercises for step-down step-up and inverting reg

In most wireless communications systems convolutional coding is the preferred method of error-correction coding to overcome transmission distortions. This report outlines the theory of convolutional coding and decoding and explains the programming techniques for Viterbi decoding in the Texas Instruments TMS320C55x™ generation of digital signal processors (DSPs). The same basic methods deco

This report presents algorithms and code implementing floating-point addition subtraction multiplication and division with the TMS320. The support of floating-point operations by the TI processors has made possible some applications such as the implementation of the CCITT Adaptive Differential Pulse Code Modulation (ADPCM) algorithm and image/graphics operations.
