Digital frequency meter using DMA Terminal Count stop method
Abstract-
This paper presents a new wide-range speed
measurement method, using the direct memory access
(DMA) terminal count register(TCR). The DMA
method is based on both pulse counting in the constant
sampling time at terminal count stop pin of a DMA
controller. The hardware configuration and algorithms
for a microcontroller implementation are also
presented. The proposed method is suitable in systems
using microcontrollers with DMA controller and
timers. Li ....etc

C++ Lex using CSharp is a system software ( Lexical Analyzer) project where the input program is broken down into many fragments called tokens. Basically lexical analysis involves scanning the program to be compiled and recognizing the tokens that make up the source statements. Scanners are usually designed to recognize keywords, operators, and identifiers, as well as integers, floating point numbers, character strings, and other similar items that are written as part of source program. The exact set of tokens to be recognized depends upon the ....etc
