3 nyeem thiab hloov chaw nyob ntawm lub cuab yeej
(1) Nyeem lossis nug qhov chaw nyob
Yog tias koj tsis paub qhov chaw nyob ntawm lub cuab yeej tam sim no thiab tsuas muaj ib lub cuab yeej ntawm lub npav, koj tuaj yeem siv cov lus txib FA 03 00 64 00 02 90 5F Lus nug ntaus ntawv chaw nyob.
| Ntaus ID | Function id | Pib Chaw Nyob | Cov Ntaub Ntawv Ntev | CRC 16 |
| FA | 03 | 00 | 00 | 90 5F |
FA yog 250 rau qhov chaw nyob dav dav. Thaum koj tsis paub qhov chaw nyob, koj tuaj yeem siv 250 kom tau txais qhov chaw nyob ntawm lub cuab yeej tiag, 00 64 yog tus qauv ntaus ntawv sau npe.
Rau cov lus nug kom raug, lub cuab yeej yuav teb, piv txwv liample, cov ntaub ntawv teb yog: 01 03 02 07 12 3A 79, hom ntawv uas yog raws li qhia hauv qab no:
| Ntaus ID | Function id | Pib Chaw Nyob | Qauv Ntawm Cov Qauv | CRC 16 |
| 01 | 03 | 02 | 55 3c 00 01 | 3A 79 |
Cov lus teb yuav tsum yog nyob rau hauv cov ntaub ntawv, thawj byte 01 qhia tias qhov chaw nyob tiag tiag ntawm lub cuab yeej tam sim no yog, 55 3C hloov mus rau kaum xyoo 20182 qhia tias tam sim no tus qauv tseem ceeb ntawm lub cuab yeej yog 21820, thiab qhov kawg ob bytes 00 01 Qhia tias lub cuab yeej muaj cov xwm txheej kom muaj nuj nqis.
(2) Hloov chaw nyob ntawm lub cuab yeej
Rau example, yog tias qhov chaw nyob tam sim no yog 1, peb xav hloov mus rau 02, cov lus txib yog: 01 06 00 66 00 02 E8 14.
| Ntaus ID | Function id | Pib Chaw Nyob | Qhov chaw | CRC 16 |
| 01 | 06 | 00 | 00 | E8 14 |
Tom qab qhov kev hloov pauv tau ua tiav, lub cuab yeej yuav rov qab cov ntaub ntawv: 02 06 00 66 00 02 E8 27, nws hom ntawv tau txheeb raws li qhia hauv qab no:
| Ntaus ID | Function id | Pib Chaw Nyob | Qhov chaw | CRC 16 |
| 01 | 06 | 00 | 00 | E8 27 |
Cov lus teb yuav tsum yog nyob rau hauv cov ntaub ntawv, tom qab kev hloov kho tiav, thawj byte yog qhov chaw nyob tshiab. Tom qab qhov chaw nyob dav dav hloov pauv, nws yuav siv tam sim ntawd. Lub sijhawm no, tus neeg siv yuav tsum hloov cov lus nug ntawm cov software tib lub sijhawm.
4 Nyeem thiab hloov pauv tus nqi Baud
(1) Nyeem baud tus nqi
Tus ntaus ntawv lub Hoobkas baud tus nqi yog 9600. Yog tias koj xav tau hloov nws, koj tuaj yeem hloov nws raws li cov lus hauv qab no thiab cov txheej txheem sib txuas lus. Rau example, nyeem cov cuab yeej tam sim no tus baud tus nqi ID, cov lus txib yog: 01 03 00 67 00 01 35 D5, nws hom ntawv yog parsed raws li hauv qab no.
| Ntaus ID | Function id | Pib Chaw Nyob | Cov Ntaub Ntawv Ntev | CRC 16 |
| 01 | 03 | 00 | 00 | 35d 5 |
Nyeem baud tus nqi encoding ntawm lub cuab yeej tam sim no. Baud tus nqi encoding: 1 yog 2400; 2 yog 4800; 3 yog 9600;. 4 yog 19200; 5 yog 38400; 6 yog 115200.
Rau cov lus nug kom raug, lub cuab yeej yuav teb, piv txwv liample, cov ntaub ntawv teb yog: 01 03 02 00 03 F8 45, hom ntawv uas yog raws li qhia hauv qab no:
| Ntaus ID | Function id | Cov Ntaub Ntawv Ntev | Tus nqi ID | CRC 16 |
| 01 | 03 | 02 | 00 | f8 45 ua |
coded raws li baud tus nqi, 03 yog 9600, piv txwv li cov cuab yeej tam sim no muaj baud tus nqi ntawm 9600.
(2) Hloov tus nqi baud Rau example, hloov tus nqi baud ntawm 9600 rau 38400, piv txwv li hloov cov cai ntawm 3 mus rau 5, cov lus txib yog: 01 06 00 67 00 05 F8 1601 03 00 66 00 01 64 15 .
| Ntaus ID | Function id | Pib Chaw Nyob | Lub hom phiaj Baud Rate | CRC 16 |
| 01 | 03 | 00 | 00 | 64 |
Hloov tus nqi baud ntawm 9600 mus rau 38400, hloov cov cai los ntawm 3 mus rau 5. Tus nqi baud tshiab yuav siv tam sim ntawd, thaum lub sij hawm lub cuab yeej yuav poob nws cov lus teb thiab baud tus nqi ntawm cov cuab yeej yuav tsum tau nug raws li. Hloov kho.
Nyeem Kev Kho Tus Nqi
(1) Nyeem Kev Kho Tus Nqi
Thaum muaj qhov yuam kev ntawm cov ntaub ntawv thiab cov qauv siv, peb tuaj yeem txo qhov kev ua yuam kev los ntawm kev kho tus nqi kho. Kev kho qhov sib txawv tuaj yeem hloov tau los ua ntxiv lossis rho tawm 1000, uas yog, tus nqi ntau yog 0-1000 lossis 64535 -65535. Rau example, thaum tus nqi zaub me dhau, peb tuaj yeem kho nws los ntawm kev ntxiv 100. Cov lus txib yog: 01 03 00 6B 00 01 F5 D6 . Hauv qhov hais kom ua 100 yog hex 0x64 Yog tias koj xav tau txo, koj tuaj yeem teeb tsa tus nqi tsis zoo, xws li -100, sib haum rau tus nqi hexadecimal ntawm FF 9C, uas yog xam raws li 100-65535 = 65435, thiab tom qab ntawd hloov mus rau hexadecimal rau 0 x f9c. Tus nqi kho yog pib ntawm 00 6B. Peb coj thawj parameter ua ib qho example. Tus nqi kho yog nyeem thiab hloov kho tib yam rau ntau yam tsis muaj.
| Ntaus ID | Function id | Pib Chaw Nyob | Cov Ntaub Ntawv Ntev | CRC 16 |
| 01 | 03 | 00b ib | 00 | F5 D6 |
Rau cov lus nug kom raug, lub cuab yeej yuav teb, piv txwv liample, cov ntaub ntawv teb yog: 01 03 02 00 64 B9 AF, hom ntawv uas yog raws li qhia hauv qab no:
| Ntaus ID | Function id | Cov Ntaub Ntawv Ntev | Cov ntaub ntawv tus nqi | CRC 16 |
| 01 | 03 | 02 | 00 | AB 9 AF |
Hauv cov ntaub ntawv teb, thawj byte 01 qhia qhov chaw nyob ntawm lub cuab yeej tam sim no, thiab 00 6B yog thawj lub xeev cov nqi kho tus nqi sau npe. Yog tias lub cuab yeej muaj ntau qhov tsis sib xws, lwm yam tsis ua haujlwm hauv txoj kev no. Ib yam nkaus, qhov kub thiab av noo muaj qhov ntsuas no, lub teeb feem ntau tsis muaj cov khoom no.
(2) Hloov kho tus nqi
Rau example, yog tias lub xeev tam sim no muaj tsawg dhau, peb xav ntxiv 1 rau nws qhov tseeb tus nqi, thiab tus nqi tam sim no ntxiv rau 100 kev kho cov lus txib yog: 01 06 00 6B 00 64 F9 FD.
| Ntaus ID | Function id | Pib Chaw Nyob | Qhov chaw | CRC 16 |
| 01 | 06 | 00b ib | 00 | F9 FD |
Tom qab kev ua haujlwm tiav, lub cuab yeej yuav rov qab cov ntaub ntawv: 01 06 00 6B 00 64 F9 FD, cov kev txwv yuav siv tam sim tom qab kev hloov pauv tiav.
Tsis lees paub
