Daim npav nco tso cai rau koj khaws cov ntaub ntawv thiab hloov nws ntawm ib lub computer mus rau lwm lub. Txhawm rau ua daim npav nco koj tus kheej, koj yuav tsum yuav lub tshuab hluav taws xob cais, lub cim xeeb nti, USB txuas, lub rooj tsav xwm los ntawm lub khw muag khoom xov tooj cua. Koj tseem yuav xav tau lub zog, resistors, coils, thiab ib tug siv lead ua resonator.
Nws yog qhov tsim nyog
- - khob cij board;
- - soldering hlau;
- - nco chips thiab maub los;
- - programmer;
- - ib puag ncig lub cajmeem.
Cov Lus Qhia
Kauj ruam 1
Xaiv tus tswj hwm rau cov cim xeeb roj koj muaj. Ua tib zoo saib lawv cov interface. Nws raug nquahu kom siv cov qauv interface, yog tias muaj. Txwv tsis pub, koj yuav tsum ua nws koj tus kheej. Nco ntsoov tias txoj kev xa khoom sib kis zoo ib txwm muaj kev ua tau zoo dua cov ntu txuas ntxiv. Siv cov khoom siv tswj hwm uas txhawb USB. Ib qho ntxiv, qee tus neeg tswj hwm txhawb nqa cov kab ke cov ntaub ntawv tshaj plaws hauv kho vajtse.
Kauj ruam 2
Xav txog lub tswvyim ntawm daim npav nco txog yav tom ntej. Nco ntsoov tias kev siv tam sim no yuav tsum tsis pub ntau tshaj 500 mA rau USB1 thiab USB2. Nws raug nquahu kom tso lub peev xwm lim loj ntawm cov tswv yim ntawm lub cuab yeej, yog li thaum lub zog tsis ua haujlwm, nws tuaj yeem sau cov kab ke system. Hauv qhov no, lub sijhawm them tam sim no ntawm tus capacitor yuav tsum qis dua 500 mA.
Kauj ruam 3
Tsim lub khob cij kom debug lub cuab yeej yav tom ntej. Rau lub hom phiaj no, microcircuits hauv DIP cov pob khoom tau zoo, thiab rau SMD cov khoom siv, cov chaw tsim kho tshwj xeeb nrog cov xov tooj sib tiv tauj tau tsim tawm. Nyob rau theem no, nws zoo dua los xaiv lub cuab yeej loj dua, rau qhov yooj yim ntawm kev tsim kho ntxiv.
Kauj ruam 4
Cov kauj ruam tom ntej yog qhov ua cov cuab yeej. Tam sim no koj yuav tsum tau ua pa lub neej mus rau hauv ib pawg ntawm cov chips, xaim, kab thiab cov txuas. Ntxiv rau cov qauv kev ua haujlwm ntawm lub cim xeeb daim npav, koj tuaj yeem ua kom tiav nws nrog cov peev txheej muaj qhov tsuas yog los ntawm koj qhov kev xav. Piv txwv li, nkag mus rau cov ntaub ntawv encryption, qhia cov chaw qhia, rov qab rau ib qho microchip ntxiv, thiab lwm yam. Nco ntsoov tias tsis muaj kev tiv thaiv me ntsis teeb, qhov kev zov me nyuam nco ntawm tus maub los yuav nyeem tau yooj yim. Yog tias feem ntau tsuas yog cuam tshuam nrog qhov poob ntawm qhov program code, tom qab ntawv ntawm cov ntaub ntawv encryption, txhua yam kev siv coj los tiv thaiv yuav tsis muaj nuj nqis.
Kauj ruam 5
Tom qab debugging cov software thiab kho vajtse ntawm lub cuab yeej, koj tuaj yeem sib sau ua ke qhov kawg ntawm pawg tswj hwm nrog txo qhov loj me, nqi rau ib qho cuab yeej, thiab qhov chaw yooj yim ntawm cov ntsuas.
