Lub hauv paus ntsiab lus tseem ceeb ntawm cov koob yees duab rau kev thaij duab yog tsim los ntawm lub teeb liab los tswj hwm lub koob yees duab ntawm kev raug, thiab kev xa duab, thiab cov duab xa tawm. Cov txheej txheem no tuaj yeem muab faib ua kev sib txuas thiab sab nraud ua kom sab nraud, txhua qhov sib xws rau cov xwm txheej sib txawv.
1. Sab hauv triggering:Duab ntes thiab nres yog tswj los ntawm kev xa khoom software, nrog kev ntes tus ncej tseem tswj tau software;
Cov txiaj ntsig zoo: Kev Tsim Kho Siab, Kev Tswj Yooj Yim, Tsis Muaj Kev Siv Hluav Taws Xob Ntxiv, thiab Yooj Yim Rau Debugging;
Qhov tsis zoo: hauv cov loj - nplai ua cov haujlwm, lub sijhawm tswj tsis txaus, thiab latency yuav nce ntxiv.
2. Sab Nraud:Ib qho khoom siv sab nraud txuas rau lub koob yees duab los ntawm nws cov I / o interface, thiab lub teeb liab pib raug xa los ntawm cov cuab yeej sab nraud mus rau lub koob yees duab los pib duab.
Cov txiaj ntsig zoo: siab lub sij hawm tswj kev txhawj xeeb, thiab ruaj khov mult {{mult} cov koob yees duab pib;
Qhov tsis zoo: Kev daws teeb meem yuav siv sijhawm ntev dua thaum tsim teeb meem.
Sab Nraud TRIGGERING Meej Classification:
1. Ntug Rau Hom.
Xaiv yog lub nce ntug lossis poob ntug raws li cov lus tsis muaj mob. Thaum muaj lub teeb liab uas muaj tau txais nyob rau ntawm lub davhlau ya nyob twg hauv lub davhlau ya nyob twg, lub koob yees duab pib ntes cov ncej ntawm cov duab thiab xa lawv mus rau tus tswv tsev.
2. Qib pib hom.
Xaiv cov qib siab lossis theem qis dua li cov khoom tsis muaj mob. Thaum lub teeb liab pib mus txog ib qib siv tau, lub koob yees duab pib ntes cov ncej ntawm cov duab thiab xa lawv mus rau tus tswv tsev.
Overlapping kev raug thiab tsis -} overlapping kis
Lub koob yees duab tau txais cov duab duab hauv ob theem: raug thiab nyeem ntawv. Nyob ntawm seb hom ntawm sensor siv los ntawm lub koob yees duab, kev sib tshooj ntawm lub sijhawm raug ntau yam, ua rau muaj ob hom: Overlapping kis thiab tsis yog}} ratedlapping kis tau.
1. Tsis -} overlapping raug:Tsis -} Tshaj tawm cov txheej txheem hais txog cov txheej txheem uas raug rau cov ncej tam sim no ua tiav ua ntej kev sib kis thiab nyeem cov ncej tom ntej. Lub voj voog voj voog ntawm tsis- overlapping kis tau loj dua tshaj qhov tawm ntawm lub sijhawm thiab lub sijhawm nyeem ntawv.
Cov lus teb hom:Lub koob yees duab tuaj yeem teeb tsa cov duab ntes ntawm ntug kev nce, poob ntug, qib siab, lossis theem qis ntawm ib theem sab nraud.
Ua raws kev ncua qeeb:Lub sijhawm ncua sijhawm tau txais lub teeb liab pib ntawm lub koob yees duab thiab qhov tseeb teb rau lub teeb liab los ua ib daim duab tuaj yeem tsim tsa raws li qhov ua rau qeeb.
CE TRIGGER CACHA TUAJ:Lub koob yees duab muaj cov cache ua rau muaj kev ua haujlwm, uas txhais tau tias yog tias lub cim tshiab ua haujlwm tau txais thaum lub sijhawm ua rau lub teeb liab, cov teeb liab tuaj yeem khaws cia thiab ua tiav. Lub cache cache pab ua haujlwm tuaj yeem tuav tau thiab cov txheej txheem txog ob qho cim taw qhia.
Piv txwv tias yog qhov kev ua yeeb yam tam sim no yog thawj zaug, yog tias lub koob yees duab tau txais lub teeb liab thib ob uas tsis muaj teeb meem thib ob ntawm lub teeb liab, lub teeb liab thib ob yog siv ncaj qha thiab tsis ua haujlwm.
Pab kom muaj kev txiav txim siab cache:Qhov thib ob txhais cov teeb liab yog khaws cia. Yog hais tias lub sij hawm kis tau kawg ntawm thawj cov duab kos duab ntawm lub teeb liab thib ob ntawm lub cim kawg ntawm lub koob yees duab kawg ntawm lub koob yees duab kawg ntawm lub koob yees duab thib ob ntawm lub teeb liab thib ob ntawm lub teeb liab thib ob yuav tso zis ib txwm ua.
Yog hais tias lub sij hawm kis tau kawg ntawm thawj tus ncej ntawm lub teeb liab thib ob ntawm thawj lub teeb liab, lub koob yees duab yuav ua ntej ntawm thawj lub sijhawm pib ntawm lub sijhawm kawg ntawm lub sijhawm kawg ntawm lub cim kawg ntawm thawj lub teeb liab.
Anti - co co stigger:Cov cim sab nraud tau xa mus rau lub koob yees duab yuav muaj suab nrov, uas tuaj yeem ua rau muaj cov cim tsis tseeb yog tias lawv nkag lub koob yees duab ncaj qha. Hauv qhov no, lub teeb liab theem pib tuaj yeem ua kom muaj suab nrov.
Cov khoom lag luam tawm cov teeb liab:Lub koob yees duab lub teeb tsa cov teeb liab yog lub teeb liab hloov uas tuaj yeem siv los tswj cov khoom siv sab nraud xws li lub teeb pom kev zoo, teeb tsa, thiab PLCS. Lub stigger tso zis teeb liab tuaj yeem yog qib -} inverted.
01 Lub Koob Yees Duab I / O
Kuv cov cim I / o hauv lub koob yees duab yog Bidirectional I / O, uas tuaj yeem siv ua cov cim qhia ntawv lossis cov cim tawm tsam.
Kho kev teeb tsa I / O raws li cov tswv yim
02 i / o Wiring Daim Duab
Thaum lub koob yees duab siv Bidirectional I / O raws li lub teeb tsa zoo ua rau lub teeb liab pib, cov xov hlau sib txawv nyob ntawm sab nraud ntawm cov teeb liab.
Cov paib tawm tswv yim yog PNP ntaus ntawv
Cov paib tawm tswv yim yog cov NPN ntaus ntawv
Cov paib qhia yog hloov, thiab tus hloov yuav tuaj yeem muab qib qis kom ua tiav Bitirectional I / O ua rau.
03 i / o Wiring Daim Duab
Thaum lub koob yees duab siv Bidirectional I / O raws li cov teeb liab kos duab, cov xaim hluav taws xob nyob ntawm cov khoom sib txuas.
Sab Nraud Pnp Ntaus Ntawv Sab Nraud
Sab Nraud NPN ntaus ntawv
Lub Koob Yees Duab thiab Cov Hluav Taws Xob Xov Xwm Hlau
