A bootloader enables field updates of application firmware. A controller area network (CAN) bootloader enables firmware updates over the CAN bus. The CAN bootloader described in this application report is based on the Hercules™ ARM® Cortex™-R4 microcontroller. This application report describes the CAN protocol used in the bootloader and details each supported command.
This application report serves as a reference for engineers designing with Xilinix <TM> 2.5-V and 1.8-V Virtex <TM> multivoltage FPGA products. It provides basic information on the issues facing engin
This application report implements a Texas Instruments 4-wire touch screen controller (TSC) to control an 8-wire touch screen and discusses features and performances for such applications. Texas In
The Texas Instruments family of audio converters can be used in various multichip configurations in order to realize multichannel processing using the time-division multiplexing (TDM) feature. Using a
TPS54040, TPS54060, TPS54140, TPS54160, TPS54040A, TPS54060A, TPS54140A, TPS54160A Differences between the TPS54x40, TPS54x60 and the TPS54x40A, TPS54x60A
Many servo applications require absolute position information as feedback. This document describes how the encoder count can be processed to obtain absolute position on the TMS320C240. The document in
Ultrasonic flow meters are gaining wide usage in commercial industrial and medical applications. Major benefits of utilizing this type of flowmeter are higher accuracy low maintenance (no moving parts) non-invasive flow measurement and the ability to regularly diagnose health of the meter. This application note is intended as an introduction to ultrasonic time-of-flight (TO
The optocoupler is often used in pulse-width-modulated power converters to transmit an error signal across an isolation boundary. This error signal is used on the primary side to close the control loop. This application note describes a typical optocoupler feedback scheme using the UC3965 Precision Reference with Low-Offset Error Amplifier and a Siemens Optoelectronics IL207 optocoupler. The discu
This application report describes an interface between the Texas Instruments TMS320C6000™ DSP host port and the PLX Technology PCI9050 (PCI9052) the PCI interface chip. The PCI9052 is functionally the same as the PCI9050. The only difference between these two devices is that the PCI9052 is somewhat faster than the PCI9050.This application report includes a diagram showing connections be
UCC3958 is a monolithic BCMOS lithium-ion battery protection circuit that enhances the useful operating life of one-cell rechargeable battery packs. The UCC3958 demo board provides complete overcharge undercharge and overload/short circuit protection for a single lithium-ion cell. The schematic and parts list of the demo board are included in this design note.
The MSP430™ is an ideal microcontroller solution for low-cost low-power precision sensor applicationsbecause it consumes very little power. The LMP91200 is a configurable sensor analog front end (AFE) foruse in low power analytical sensing applications. This library provides functions to facilitate the interfacingof any MSP430 device to a LMP91200. Any device within the MSP430 family
The performance and complexity of video codecs is driven by several factors. Algorithm design/flow is just one of these factors. Other important factors are device architecture software architecture resource availability and usage etc. to name a few. However one of the most important factors that are often ignored in the codec development cycle is the complete system architecture and the targ
This application note provides a summary of differences between existing Sandstorm class devices and new Fury class devices in the Stellaris family of microcontrollers.
