Converting Data Formats Between BMP and COFF Files for TMS320 DSP Simulation
Texas InstrumentsThis application report is aimed at digital signal processor (DSP) software development engineers working with image processing algorithms. The report focuses on the conversion process using data format converting utilities supporting the Texas Instruments (TI)(tm) TMS320 (C1x/C2x/C2xx/C5x/C54x) fixed-point digital signal processor (DSP) in COFF format.Basically two main software tools are re
OA-27 Low-Sensitivity, Lowpass Filter Design (Rev. B)
Texas InstrumentsThis application report covers the design of a Sallen-Key (also called KRC or VCVS [voltage-controlled, voltage-source]) lowpass biquad with low component and op amp sensitivities. This method is val
Using TDM Function to Interface Four AIC33 CODECs with a Single Host Processor
Texas InstrumentsThis application report discusses how to use the TLV320AIC33 audio data port's time-division multiplexing (TDM) function to connect interface and run four TLV320AIC33 codec devices simultaneously under the control of a single host processor. Four TLV320AIC33 EVM boards and one USB-MODEVM board were used to test the interface and function.

Custom Bootloader Options via One-Time Programmable (OTP) Memory
Texas InstrumentsThe Boot to One-Time-Programmable (OTP) memory mode in the TMS320x280x devices provides the necessary hooks to support custom bootloaders. This is very useful in a situation where a bootloader option required by a specific customer application is not already supported as one of the built-in options in the Boot read-only memory (ROM). This application report includes information and examples on h
AN-2168 LMZ10501 and LMZ10500 SIMPLE SWITCHER Nano Module EMI Performance (Rev. A)
Texas InstrumentsThe LMZ10501 and LMZ10500 nano modules offer excellent EMI performance. The evaluation board withthe default components complies with the CISPR 22 Class B radiated emissions standard. Adding twosmall 0.1μF 0805 input capacitors results in CISPR 25 Class 5 radiated emissions standard compliance.The addition of a small LC filter (1μH and 1μF) to the input of the default evaluation board result
NFC Active and Passive Peer-to-Peer Communication Using the TRF7970A

Interfacing the ADS8383 to TMS320C6711 DSP
Texas InstrumentsThis application note presents a software and hardware interface of the ADS8383 18-bit 500 kHz analog-to-digital converter to the TMS320C6711 DSP. The hardware platform used to develop this application is ADS8383EVM and TMS320C6711 DSK. The software developed reads 1024 blocks of samples continuously from ADS8383. In an effort to reduce development time the source code is available on TI's websit
Monotonic, Inrush Current Limited Start-Up for Linear Regulators
Texas InstrumentsThe output voltage of a linear regulator tends to rise quickly after it is enabled. This often results in the nonmonotonic rise of the output voltage (i.e., the output voltage overshoots, then dips),
ADC Source Impedance for Hercules ARM Safety MCUs (Rev. B)
