Use of Two MSP430s to Enhance Segment Lines for Larger LCDs (Rev. A)
Texas InstrumentsThis application report explains a technique that uses two MSP430™ microcontrollers to expand the maximum number of LCD segments that can be driven with a single controller. Additional benefits of the technique include increases in available memory data storage (RAM) and I/O control lines. These benefits are realized without the need for an external LCD driver circuit. The use of a second
AN-1997 Error Amplifier Limitations in High-Performance Regulator Applications (Rev. A)
Texas InstrumentsThe development of realistic predictions to assist the power supply engineer during the control loop design process is facilitated in this application report by appropriate small-signal and bode plot analysis the validity of which is verified through simulation results.
Data Converters for Industrial Power Measurements (Rev. B)
Texas InstrumentsSources of noise generation are pervasive in contemporary industrial applications. Unwanted noise presents one of the major problems in measuring power or protecting circuits in such an environment. Knowing the characteristics and understanding the behavior of noise sources are valuable to designers and users of electronic circuits. The first part of this report defines some fundamental concepts o

TPS312x Series Supervisory Circuits in Ultra-Low-Voltage Applications
Texas InstrumentsVoltage-monitoring circuits are firmly established in microcomputer systems. These circuits perform system initialization which includes circuit reset and they monitor the supply voltage during operation. When combined with watchdog circuits they monitor the proper functioning of a device in safety-relevant circuits. This report describes the new TPS312x series of voltage-monitoring integrated
Calling Convention and ABI Changes in MSP GCC
Texas InstrumentsThe new GCC compiler for MSP low-power microcontrollers (MSP430-GCC-OPENSOURCE) conforms to the MSP Embedded Application Binary Interface (EABI) (see SLAA534). This allows GCC to interoperate with the proprietary TI compiler. For example assembly functions can be written in the same way and libraries that are built with one compiler can be used as part of executables built with the other compile

Adaptive Active Noise Control for Headphones Using the TMS320C30 DSP
Texas InstrumentsProlonged exposure to excessive levels of acoustic noise can cause permanent hearing loss safety problems and lower work productivity. An adaptive controller that optimally cancels unwanted acoustic noise while allowing the desired sounds such as speech and warning signals would be particularly useful for people using heavy machinery or working near engines. This document describes the design
Texas Instruments Voltage-Level-Translation Devices (Rev. A)
Texas InstrumentsIn electronic systems design there is a need to provide an interface between different voltage levels. Texas Instruments offers four split-rail bus transceivers with dual voltage-supply inputs. These transceivers allow translation between 3.3-V LVTTL/LVCMOS and 5-V CMOS 2.5-V CMOS and 5-V CMOS and 2.5-V CMOS and 3.3-V LVTTL/LVCMOS. These devices are the SN74LVCC3245A SN74LVC4245A SN74LVCC4245
