Calculator driver -Free
Driver enables to simply calculate functions and complex expressions/formulas and process string variables. Driver adds possibility to use in Composer Programming mathematical functions (sin,pow,log,sqrt,modulo,binary/bitwise operations..), and in from NEW version 1.1.8 also string parsing and text conversion functions.
Driver calculates formulas and expression easily entered either directly in to driver property or supplied in custom text strings. Driver contains 26 NUMBER and 20 STRING variables from which custom formulas can be assembled. It is possible to copy the contents between the system and user defined variables.
In formulas can be used all operators and functions supported by Lua in Director (version 5.1 + ). For string operations is particulary suitable string library available at http://lua-users.org/wiki/StringLibraryTutorial.
Calculator driver is usefull complement to Generic Serial Driver as together it allows to process by Composer Pro Programming third party bidirectional communication protocols on RS232/RS485
Features/Properties
Contains 26 auxiliary NUMBER and STRING variables which can be used in custom formulas and expressions
Contains variable Result (type NUMBER,STRING,BOOL) containing result of the expression evealuation
Applications:
· Calculations of constants/averages/ratios and parameters of systems in temperature control and power consumption metering applications
· Processing and evaluation of data from devices using proprietary text based protocols -thermometers, humidity meters …
· Preparations and assembly of commands and protocol messages for proprietary binary and text protocol controlled devices I/O modules, D/A converters, irrigation systems...
