FX4 Programming Tshajview
Lub FX4 processor khiav ntawm ib puag ncig hu ua IGX, uas yog tsim los ntawm QNX kev ntseeg siab ntawm lub sijhawm ua haujlwm ntawm BlackBerry (QNX Webqhov chaw¹). IGX muab qhov hloov pauv tau yooj yim thiab ua tiav daim ntawv thov programming interface (API) rau cov neeg siv uas xav sau lawv tus kheej lub khoos phis tawj software.
IGX ib puag ncig tau sib koom thoob plaws lwm cov khoom lag luam Pyramid, tso cai rau kev daws teeb meem software tsim rau ib yam khoom kom yooj yim xa mus rau lwm tus.
Programmers tuaj yeem xa mus rau cov ntaub ntawv ua tiav rau IGX muaj nyob ntawm Pyramid webqhov chaw ntawm: IGX | Niaj hnub nimno Modular Control System Framework rau Web-enabled Applications²
Tshooj lus no qhia txog kev sim ob txoj hauv kev API: HTTP siv JSON hom thiab EPICS. Rau kev yooj yim, Python (Python Webqhov chaw³) yog siv los ua example host computer language, uas yog siv tau thiab siv tau yooj yim rau cov programmer uas tsis yog tus kws tshaj lij.
3.1 Siv Python thiab HTTP
Raws li ib tug example, xav tias koj xav nyeem cov lej ntawm cov ntsuas tam sim no nrog Python. Koj xav tau cov URL rau qhov tshwj xeeb IO. FX 4 web GUI muab txoj hauv kev yooj yim los nrhiav qhov no: tsuas yog nyem rau hauv daim teb thiab xaiv 'Copy HTTP URL' los luam cov hlua rau hauv daim ntawv teev cia.
Tam sim no koj tuaj yeem siv Python los ntsuas kev sib txuas rau cov neeg siv software ntawm HTTP thiab JSON. Tej zaum koj yuav xav tau import cov ntawv thov thiab json cov tsev qiv ntawv los ua cov lus thov HTTP thiab kev txheeb xyuas cov ntaub ntawv.

3.2 Siv EPICS
Cov txheej txheem rau kev txuas FX4 los ntawm EPICS (Kev Tshawb Fawb Physics thiab Industrial Control System) zoo ib yam. EPICS yog cov cuab yeej software thiab cov ntawv thov siv los tsim thiab siv cov kev tswj hwm kev faib tawm, dav siv hauv cov chaw tshawb fawb.
- Tau txais EPICS cov txheej txheem sib txawv (PV) lub npe rau qhov xav tau IO.
- Ntshuam lub tsev qiv ntawv EPICS thiab nyeem tus nqi.
2 Tau EPICS PV Lub Npe
3 Yooj Yim Python EPICS Example
Tsis tas li ntawd, Pyramid tsim cov khoom siv hluav taws xob (EPICS Txuas⁴) uas tso cai rau koj los saib xyuas EPICS cov txheej txheem hloov pauv hauv lub sijhawm. Cov cuab yeej no yuav pab tau kom paub meej tias EPICS PV lub npe yog lawm thiab FX4 tab tom ua haujlwm rau PV kom raug ntawm koj lub network.

FX4 Python Examples
5.1 Cov Ntaub Ntawv Logger siv HTTP
Qhov no example ua qauv qhia yuav ua li cas ntes tau ntau tus nyeem ntawv thiab khaws cia rau hauv CSV file. Los ntawm kev xaiv qhov ncua sij hawm ntev ntawm kev nyeem ntawv, koj tuaj yeem ua cov ntaub ntawv mus sij hawm ntev txawm tias FX4 sampling tus nqi yog teem siab dua. Qhov no tso cai rau koj txuas ntxiv mus sau thiab khaws cov kev ntsuas nyob rau lub sijhawm txuas ntxiv yam tsis muaj kev cuam tshuam rau lub system, kom ntseeg tau tias cov ntaub ntawv raug ntes ntawm lub sijhawm tsim nyog rau koj qhov kev tshuaj xyuas. Qhov ncua sij hawm ntawm kev nyeem ntawv pab tswj cov pace ntawm cov ntaub ntawv nkag, tso cai rau kev khaws cia kom zoo thiab txo qhov kev pheej hmoo ntawm cov ntaub ntawv ploj lawm thaum tseem tau txais txiaj ntsig los ntawm kev kub ceev s.ampling rau kev ntsuas lub sijhawm.
5.2 Yooj Yim Python GUI
Ob example siv cov cuab yeej Tkinter GUI, uas yog tsim rau Python, los tsim ib qho screen ntawm ntsuas tam sim no. Qhov no interface tso cai rau koj mus pom cov kev nyeem tam sim no nyob rau hauv ib tug user-friendly graphical hom ntawv. Cov zaub tuaj yeem hloov pauv kom nws loj txaus los nyeem los ntawm thoob plaws ib chav, ua rau nws zoo tagnrho rau cov xwm txheej uas xav tau kev saib xyuas lub sijhawm tiag tiag hauv qhov chaw loj dua. Tkinter muab txoj hauv kev yooj yim los tsim kev sib tham sib cuam tshuam, thiab los ntawm kev sib koom ua ke nrog FX4, koj tuaj yeem tsim cov duab pom ntawm cov ntsuas tam sim no uas tuaj yeem hloov kho kom haum rau koj cov kev xav tau tshwj xeeb.
5.3 Yooj yim WebSockets Example
Qhov no example demonstrates cov WebSockets interface, uas yog txoj kev nyiam rau kev nyeem cov ntaub ntawv los ntawm FX4 thaum qhov siab tshaj plaws bandwidth xav tau. WebCov qhov (sockets) muab lub sijhawm tiag tiag, puv-duplex kev sib txuas lus channel, tso cai rau kev hloov pauv cov ntaub ntawv sai dua thiab ua haujlwm zoo dua piv rau lwm txoj hauv kev.
Cov example nyeem ib tug series ntawm samples, qhia lub sijhawm nruab nrab ntawm ib sample thiab siab tshaj plaws latency, thiab txuag cov ntaub ntawv rau CSV file rau kev txheeb xyuas tom qab. Qhov kev teeb tsa no tso cai rau kev saib xyuas lub sijhawm tiag tiag thiab khaws cov ntaub ntawv yooj yim rau kev ua tiav tom qab.
Cov kev ua haujlwm tshwj xeeb uas tuaj yeem ua tiav nrog WebSockets nyob ntawm kev ntseeg siab ntawm koj Ethernet interface thiab qhov tseem ceeb ntawm koj daim ntawv thov. Rau cov txiaj ntsig zoo, xyuas kom meej tias koj lub network ruaj khov thiab FX4 cov ntaub ntawv xa mus yog qhov tseem ceeb yog tias tsim nyog.
