Video surveillance systems are currently undergoing a transition from traditional analog solutions to digital solutions. This paper will discuss how to implement a digital video surveillance system ov
In addition to their actual operation parameter transconductance, active electronic key components such as vacuum tubes, field effect transistors, and bipolar transistors demonstrate diverse negative
This application report presents a solution for the control of brushless DC motors using theTMS320F2803x microcontrollers. TMS320F280x devices are part of the C2000™ family ofmicrocontrollers that enable the cost-effective design of intelligent controllers for three-phase motors byreducing the system components and increasing efficiency. Using these devices it is possible to realizefar mo
The Texas Instruments TFP201 is one device in a family of TI PanelBus™ flat panel display products that simplifies digital display systems design by offering value added flexibility and reliability to the system designer. The TFP201 is a DVI compliant flat panel digital receiver that supports display resolutions ranging from VGA to SXGA in 24-bit true-color pixel format. The TFP201 offers d
The CMOS ADS574 and ADS774 are drop-in replacements for industry standard ADC574 analog-to-digital converter offering lower power and the capability to operate from a single +5V supply. The switched capacitor array architecture (CDAC) with the input resistor divider network to provide ADC574 input ranges also allow the new parts to handle additional input ranges including a 0V to 5V range. Thi
This document describes filter design from the standpoint of cost. Filter design techniques that require the fewest possible op amps and passive components are described. Six types of filters are described - low pass high pass narrow bandpass wide bandpass notch and band reject.
This application report provides an overview of the technology and tools, and their applicability for the fastest turnaround time for your embedded system.
This document describes the functionality of the TMS320C6452 ROM bootloader software. The ROM bootloader resides in the ROM of the device beginning at ROM address 0x00100000. The ROM boot loader (RBL) implements methods for booting in the listed modes. It reads the contents of the BOOTCFG register to determine boot mode and performs appropriate commands to effect boot of device. If an improper boo
The paper presents an efficient method of teaching the Texas Instruments (TI(TM)) TMS320C3x digital signal processor (DSP) in the frame of a non-dedicated technical subject matter during an academic semester. Individual tasks are defined with similar difficulties and almost the same level of learning and understanding the processor capabilities. Some projects are presented as examples of the me
This application note describes how to communicate with the bq76940 family devices over I2C. The code is based on the TI MSP430G2553. The code shows how to write the CRC function which is used to verify the transaction integrity over the I2C and how to initialize the I2C engine of the G2553 and bq76940 registers as well as how to read binary data from the AFE registers and transfer the data to vol
This document provides board-level guidelines and techniques for designing with the TLC320AD50. This includes topics such as printed-circuit board construction power-supply decoupling noise reduction and general design guidelines. The intent is to provide strategies to help users attain first-pass design sucess with the TLC320AD50.
This application note describes the theory and operation of an analog gain scaling circuit that is required to obtain specified audio performance from the PCM1804.
The Texas Instruments (TI) TMS320VC5420 DSP implements limited boundary scan capability with respect to standard IEEE 1149.1 boundary scan devices. This application report contains a description of the 'VC5420 boundary scan implementation and information about how to use it with other boundary scan tools and devices.
The material covered in this application report assumes the reader is familiar
This document serves as an overview describing the use of the Timer_A UART library within an existing C or assembly project. The Timer_A UART library encapsulates commonly used routines for transmitting and receiving bytes using UART. These functions are written in assembly to be optimized for the MSP430 but can be called from any C program that includes the ta_uart.h header file.
Differential gain (DG) and differential phase (DP) are two specifications that designers of composite videosystems use everyday. We will define them here just to be sure we are all speaking the same languageand to ensure understanding of the rationale of the test technique used by Texas Instruments.
