Battery powered systems or systems with low input voltage supplies may have loads that require higher voltage outputs. A boost converter is a usual choice for non-isolated applications; however boost converters do not naturally provide system protection to downstream circuitry due to the pass path from input to output. Problems due to this pass path are now resolved with the LM5121 boost controll
This application report describes two methods of using an 8-bit serial port to receive a 16-bit data word. The first method uses the Texas Instruments (TI?) TMS320C17 ('C17) digital signal processor (DSP) 8-bit serial port to receive the 16-bit data word. The second method improves the first method by adding a counter to the hardware. This report describes the hardware and software modifications r
This application report explains the implementation of using the CDFS feature of the Mass Storage Controller (MSC) API of the USB Developer?s Package for the MSP430? Microcontroller. Utilizing Compac
The daughtercard specification is based on the interface provided with the TMS320DM642 (DM642) Evaluation Module (EVM). This specification provides the information ecessary to allow daughtercards to be designed to function with the DM642 EVM. It also provides guidelines for designing new DSP motherboards aiming to provide a compatible interface. This includes systems based on different DSPs as we
Most audio systems use either an analog-to-digital converter (ADC) or digital-to-analog converter (DAC) to interface with a digital signal processor (DSP). This application note describes how to interface the Texas Instruments (TI(TM)) TLC320AD57 ('AD57) audio band sigma-delta stereo ADC with the TI TMS320C5x ('C5x) DSP via the serial port. The hardware interface solution is provided because the s
Increasingly powerful computers and the rapidly expanding use of picture processing and CAD/CAM systems in almost all industry branches have combined to generate a greater and greater demand for higher resolution graphic monitors. Controlling the video output stages of these graphic monitors is a key to producing such high resolutions. Until recently only highly complex expensive systems have be
The AM17xx 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 anyone creating a system
The topics included in this application report are: Integer N and Basic PLL Concepts, Traditional Fractional N Concepts, and Delta Sigma Fractional N Concepts.
This application report covers software techniques and topics of interest to all MSP430 programmers. The first part of the document discusses the MSP430 standard interrupt-based code flow model, recom
The TMS320C40 includes a boot loader to allow users to load and execute programs from a host processor inexpensive ROM or other standard memory devices. This document discusses how to select the boot loader and how to use it. A schematic is included.
