WAVESHARE Bacode Scanner Module Tus Neeg Siv Qhia

WAVESHARE Bacode Scanner Module 

Kev sib txuas ntawm Hardware

Lub Hoobkas pib teeb tsa ntawm Barcode Scanner Module yog: phau ntawv scanning, USBPC tso zis. Yog hais tias tus neeg siv yuav tsum tau siv serial tso zis, koj yuav tsum tau luam theej duab qhov chaw code ua ntej thiab hloov nws mus rau serial tso zis.
Phau ntawv no yog ua raws li kev sim los ntawm kev txuas mus rau PC

USB Debugging Hardware Connection

Siv lub USB cable los txuas lub module lub USB interface rau lub PC.

Tom qab kev sib txuas, ib qho khoom siv keyboard ntxiv yuav tshwm sim hauv tus thawj tswj ntaus ntawv (tsuas yog hauv USB hom).

Yog tias tsis muaj cov khoom siv keyboard tshiab pom tom qab txuas rau lub khoos phis tawj, luam theej duab USB PC tso cai tso cai, thiab tom qab ntawd sim dua. Yog tias tseem tsis muaj lub cuab yeej lees paub, nws raug nquahu kom hloov USB cable.

USB lub PC Keyboard

Serial Chaw nres nkoj debugging Connection

Lub module txhawb serial chaw nres nkoj tso zis, thaum siv serial tso zis, koj yuav tsum tau luam theej duab qhov chaw code ua ntej hloov cov zis hom rau serial chaw nres nkoj tso zis. Lub neej ntawd serial tsis yog 9600, 8N1, thiab tus nqi baud tuaj yeem hloov kho (thov xa mus rau tus neeg siv phau ntawv).

Serial chaw nres nkoj Output

Thaum siv qhov chaw nres nkoj serial, koj yuav tsum yuav TTL rau serial chaw nres nkoj module. (Yog tias koj twb muaj lawm, koj tsis tas yuav lwm tus.)
Nco tseg: Connect Vcc to 5V, GND to GND, Rx to Tx, Tx to Rx. (Thov txheeb xyuas lub silkscreen los txuas.)

Tom qab ntawd txuas lub serial chaw nres nkoj module rau lub PC. Tom qab kev twb kev txuas, ib tug paub serial chaw nres nkoj ntaus ntawv yuav tshwm nyob rau hauv lub ntaus ntawv tus thawj tswj.

Kev kuaj xyuas

USB tso zis hom

Qhib ib daim ntawv (xws li lo lus, ntawv nyeem) ntawm lub PC, thiab nyem rau ntawm qhov chaw dub kom ua cov ntaub ntawv hauv hom kev nkag siab (piv txwv li koj tuaj yeem sau ntawv ncaj qha). Tom qab ntawd luam theej duab lub barcode, thiab cov ntsiab lus sib txuas decoded yuav nkag rau hauv daim ntawv.

Serial Port Output Hom

Qhib lub serial chaw nres nkoj pab software. (Koj tuaj yeem rub tawm nws los ntawm Wave qhia Wiki), teeb tsa tus lej chaw nres nkoj mus rau qhov lees paub los ntawm tus tswj hwm ntaus ntawv. Teem tus nqi baud rau 9600 (los yog hloov pauv yog tias muaj). Tom qab ntawd luam theej duab barcode, thiab cov ntsiab lus barcode yuav raug tso tawm mus rau tus pab cuam chaw nres nkoj serial.
