Kauj ruam 4: Python Scripting

Telit tau tsim tsa hauv Python 1.5.2 tus neeg txhais lus uas tau hloov kho me ntsis. Qee qhov ob jects tau rov qab los ntawm yav tom ntej ntawm Python, xws li cov hlua. Koj tsis tas yuav ntsaws cov tsev qiv ntawv hlua, nws twb muaj lawm, koj tuaj yeem siv cov lus txib zoo li line.split (","). Muaj qee txoj hauv kev uas koj tuaj yeem siv cov qauv hauv chav kawm thiab ua haujlwm, tab sis Telit yog qhov tsis txaus ntseeg heev txog qhov no. Muaj lub qhov rai simulation ib puag ncig koj tuaj yeem tau txais los ntawm cov neeg Telit, tab sis nws tsuas yog zoo li ua haujlwm ib nrab. Tsis muaj ib lub davhlau ya nyob twg los ntawm koj li kev pab cuam nab nab yuav raug luam tawm mus rau lub davhlau ya nyob twg tshwj tsis yog koj tshwj xeeb raws txoj kev nws. Koj tuaj yeem ua qhov no nrog cov ntawv sout.py txuas nrog. Yog tias koj ntshuam nws thawj zaug hauv tag nrho koj cov les, tag nrho cov davhlau ya nyob twg yuav xa rov mus ua ntej nrog stderr:. Tsis yog txhua yam yog qhov yuam kev. Cov tsev qiv ntawv built-inThe Telit muaj qee qhov ua hauv Python cov tsev qiv ntawv koj tuaj yeem ntshuam. SER yog piv txwv li kev sib txuas ntawm Python thiab sab hauv chaw nres nkoj, GPIO yog kev sib txuas ntawm Python thiab GPIO pins, GPS rau khaws cov ntaub ntawv GPS thiab MDM rau xa AT cov lus txib rau Telit. Yog xav paub ntau ntxiv c koj yuav tsum txheeb xyuas Telit Python Easy Script reference. Ib qho piv txwv ntawm kev siv MDM lub tsev qiv ntawv nyob hauv sms.py tsab ntawv uas teev tag nrho cov ntawv sau ntawm koj daim npav SIM. Txhua qhov ntawv sau uas koj upload yuav tsum tau khaws tseg hauv DOS hom ntawv, uas yog nrog kab CRLF xaus, lossis Telit yuav tsis tuaj yeem cais nws. Hauv VI, koj tuaj yeem ua qhov no nrog cov lus txib: teeb tsa ff = dos lossis hauv cov ntawv qhia zaub mov ntawm ntau lwm tus neeg kho kab ntawv. Txhawm rau upload tsab ntawv, koj yuav tsum paub nws qhov loj me me hauv bytes. Tom qab ntawv tsab ntawv tuaj yeem rub tawm nrog cov lus txib AT#WSCRIPT = "name.py", 901 qhov twg 901 yog qhov loj me me hauv bytes. Koj yuav tau txais >> sai uas yuav pab kom xa cov ntawv (hauv z-lub sijhawm: le> xa ntawv). Telit yuav tsum teb nrog OK yog tias qhov no ua haujlwm. Txhua daim ntawv sau uas tam sim no nyob hauv pawg thawj coj tuaj yeem sau nrog AT#LSCRIPT, uas tseem yuav sau cov npe.pyo les, tso cai rau koj los tshuaj xyuas yog tias koj cov tsev qiv ntawv uas tau sau nyob ntawd. Koj qhia meej cov ntawv tseem ceeb nrog cov lus txib AT#ESCRIPT = "name.py". Koj tseem tuaj yeem nug dab tsi cov ntawv tseem ceeb nrog AT#ESCRIPT ?. Cov ntawv yuav tom qab ntawd khau raj, lossis koj tuaj yeem ua nws tam sim ntawd nrog cov lus txib AT#EXECSCR. Qee zaum, vim li cas tseem tsis tau meej rau peb, cov tsev qiv ntawv nkag mus yuav tsis suav ua tshwj tsis yog tias koj teeb tsa lawv ua cov ntawv sau ua ntej ua raws li lub ntsiab lus yuav suav lawv, tom qab ntawv ob ject le tau siv yav tom ntej. Lus ceeb toom ntawm kev nrawm thiab suav sau Tus nab npawb txhais lus Python ntawm Telit yog heev, qeeb, qeeb heev. Yog tias koj ua txhaum koj cov cai rau hauv cov ntawv me me, sau ua ke Python les (.pyo) yuav raug cawm thiab ua rau koj cov cai khiav nrawm dua. Qhov tseeb tiag, koj xav kom koj cov ntawv tseem ceeb kom luv li sai tau, nkag mus rau lub luag haujlwm los ntawm cov tsev qiv ntawv ua ntej. Yog tias koj sau hloov lub tsev qiv ntawv dummy rau lub tsev qiv ntawv built-in ntawm Telit (MDM, SER, thiab lwm yam) ntawm koj lub khoos phis tawj, koj tuaj yeem suav sau Python ntawm koj lub computer thiab xa cov.pyc les (hloov npe rau.pyo) mus rau Telit kom txuag sijhawm.
