Razvoj LabVIEW gonilnikov za inštrument Red Pitaya

PERUŠEK, PRIMOŽ (author), Jankovec, Marko (mentor)

Uporabniki programirljivih inštrumentov želijo čim hitreje in enostavneje povezati inštrument z računalnikom. Če ti za kontrolo inštrumenta uporabljajo program LabVIEW, lahko uporabijo gonilnik za njihov inštrument. V diplomski nalogi je opisan razvoj LabVIEW-gonilnikov za inštrument Red Pitaya. Opisano je tudi delovanje omenjenega inštrumenta ter katere funkcije se upravljajo z ukazi SCPI, ki omogočajo kontrolo inštrumenta z LabVIEW-aplikacijami. Namen omenjenega gonilnika je olajšati in pospešiti sestavljanje blokovnih diagramov v programu LabVIEW za kontrolo inštrumenta Red Pitaya. Glede na funkcionalne zahteve, katerim morajo gonilniki ustrezati, se lotimo se razvoja funkcionalne in intuitivne zbirke LabVIEW-datotek, ki morajo zadostovati funkcionalnim zahtevam standardnih LabVIEW-gonilnikov. Najprej so opisani LabVIEW-gonilniki ter postopek njihovega razvoja. V tem je predstavljeno načrtovanje konceptnih VI blokov za inštrument Red Pitaya, ki nam bodo kasneje pomagali pri odločitvi strukture omenjenih blokov. Proces razvoja vključuje razvoj knjižnice VI blokov in komunikacije med računalnikom in inštrumentom ter se zaključi z gradnjo javne datoteke. Rezultat razvoja je knjižnica LabVIEW-blokov, kateri omogočajo enostavnejšo povezljivost z Red Pitaya ploščo ter lažjo uporabo komand za kontrolo omenjene plošče. Ko te bloke združimo v en projekt s smiselnimi povezavami med njimi, jim rečemo LabVIEW Instrument Driver.

• Title: Development of LabVIEW drivers for Red Pitaya instrument

Abstract

Users of programming instruments want to connect their instrument to a PC as fast and as easy as possible. In LabVIEW they can use an instrument driver. In the batchelor's thesis is described a development of LabVIEW instrument driver for Red Pitaya. Described is also an operation of the instrument and which functions are used to control Red Pitaya with SCPI commands. The main purpose of the driver is to make the application programming with the instrument easire and faster. We start with a development of functional and intuitive library of VI-s considering the functional requirements of standard LabVIEW drivers. At first we describe drivers and their development process. In the process we present a planning of concept VI blocks fort he instrument. The process of development includes a development of VI library and a communication between a personal computer and Red Pitaya. It finishes with a build of public file. The resoult of the development is a library of LabVIEW blocks, enabling easier connectivity with a Red Pitaya board and an easier use of commands controlling the board. All developed VI blocks united in one project are called LabVIEW Instrument driver.
