Applications that require PWM outputs to respond to multiple trip-zones (TZ) are challenged to determine the specific source of the TZ event.
This application report describes how to configure an ePWM module to identify the specific source of a TZ event when multiple TZ events are enabled to act on a single PWM channel.
The intent of this application report is to give the user an overview of the design process how to use the evaluation module and software and to provide helpful troubleshooting techniques.This document begins with setting up the evaluation module and working with bq Evaluation Software. Several tips for troubleshooting the software connection are included as well as navigation and what to l
This document presents the functional components of a dual-mode cellular phone as specified by the CTIA IS-54 standard. Each functional component transmitter receiver coordinator antenna assembly and control panel is discussed and the relevant algorithm given. For each algorithm the data structures used and the appropriate the implementation details are provided.
Unbuffered multiplexed ratiometric analog-to-digital converters have strict requirements on driving source impedance which are not always obvious. This application report addresses the trade-offs between source impedance and sample rate. It includes examples using the TMS470R1x family of processors in the TSC5000 process node (F10/C10). With adjustments to maximum clock rates this application no
This application report describes the design of an active 10-MHz second-order Butterworth low-pass filter useful for band-limiting applications. As an active component TI's operational amplifier type THS4001 which has a bandwidth of 300 MHz was used. The design of the filter described in this report is typical of proactical applications and the steps involved in calculating component values ca
Pi/4 D-QPSK (Pi/4 shift Differential-Quadrature Phase Shift Keying) is a four level modulation scheme first proposed by Baker in 1962 and is currently the focus of intensive research. The scheme is currently implemented in the American Digital Cellular Japanese Handy Phone and the European TETRA systems.The aim of this undergraduate project was to implement a Pi/4 Shift D-QPSK baseband modula
The first optimization step that can be performed on C source code for the TMS320C6000™ DSP platform is to use intrinsic operators. These are built-in functions in the compiler that can be directly translated to assembly code for faster execution. The C6000 DSP family fixed-point processors are organized into two main families: the TMS320C62x™ DSP and the TMS320C64x™ DSP. The C6
