iButtons yog khawm me me zoo li casings uas sib txuas lus nrog tsuas yog 2 xov. Lawv muaj zog tsis txaus ntseeg thiab txhua tus muaj tus lej tshwj xeeb uas yog kho vajtse sau rau hauv lub cuab yeej thiab tsis rov ua dua. Lawv pheej yig (kwv yees li 1 Phaus / 1, 50 Euro / $ 2)

Tus lej no tso cai rau cov yuam sij kom muaj qhov tshwj xeeb tiag tiag thiab yog li muaj kev nyab xeeb zoo. Kuv tau pom lawv siv:> raws li kom txog thaum nkag mus rau lub cuab yeej ntawm tuav> hauv cov ntaub ntawv nyiaj txiag muaj txiaj ntsig> lub computer nkag mus> raws li kev ruaj ntseg dongles siv nrog software kim. > … raws li qhov rooj xauv! Qhov teeb meem siv lawv rau tus pib, yog tias koj yuav tsum muaj peev xwm tsim kho vajtse los nyeem lawv thiab yog tias koj xauv tus yuam sij, lub ntsuas phoo ntaus ntawv tsis muaj txiaj ntsig! Cov Lus Qhia no qhia koj yuav tsim lub xauv li cas, thiab USB programmer uas tso cai rau koj sau cov yuam sij tshiab rau lub xauv hauv vib nas this, tsis tas yuav rhuav lub tsev. Ua kom lub xauv ruaj ntseg thiab hloov kho kom txog 80 tus yuam sij ib zaug. Lub xauv tuaj yeem ua haujlwm nruab nrab ntawm 5-30V AC lossis DC thiab yog li yog qhov hloov pauv tau zoo kawg; tsim los ua haujlwm zoo ib yam li koj lub qhov rooj tso hluav taws xob-koj tuaj yeem yuav qhov uas pheej yig tshaj lossis kim tshaj ib qho uas koj pom, Fail-Locked lossis Fail-Unlocked, AC lossis DC, 12V lossis 24V. Koj yuav xav tau dab tsi:> Cheebtsam (saib tom ntej)> PIC programmer> Hauv qhov rooj tso tawm. > PCB ua khoom siv (yog tias koj xav ua kom nws zoo li puurdy) NCO TSEG !!! Nov yog cov lus qhia qub uas kuv tsis tau tshaj tawm rau qee qhov laj thawj. Yog tias koj muaj teeb meem tsim nws, email rau kuv thiab kuv yuav zoo siab pab - txawm li cas los xij, kuv tsis tuaj yeem lav tias kuv tau ua kom yooj yim li sai tau - thov txim - vam tias nws yuav muab kev tshoov siab yog tias tsis muaj dab tsi ntxiv.

Kauj Ruam 1: Tus Txheej Txheem

Ua ntej koj yuav tsum txiav txim siab hom xauv twg uas koj xav tau.

FAIL SAFE/UNLOCKED tseem qhib thaum lub tsev tsis muaj zog. Qhov no feem ntau yuav siv yog tias lub qhov rooj nkag mus tau yooj yim thaum lub zog tsis ua haujlwm - piv txwv li Hluav Taws Xob FAIL SECURE/LOCKED tseem raug kaw tshwj tsis yog lub zog siv rau lub xauv. Cov no yuav tsim nyog dua thaum siv lub qhov rooj nkag ib txwm muaj, muaj lub qhov rooj ib txwm raug kaw txhua lub sijhawm, tshwj tsis yog siv lub zog. Hauv qab no yog daim ntawv qhia kom pom tias lub cuab yeej ua haujlwm li cas. Yooj yim, yog tias koj nkag mus rau tus yuam sij, microprocessor thawj zaug kuaj xyuas seb nws puas yog tus lej yuam sij, lossis nws yog tus yuam sij nkag. Yog tias nws yog [iButton] nkag tus yuam sij, microprocessor kuaj xyuas cov npe ntawm cov yuam sij uas paub hauv nws EEPROM (nco), yog tias nws pom nws, nws tso cai rau koj. Txwv tsis pub nws yuav xa lub teeb liab los hais tias tsis muaj kev nkag mus tau txais. Yog tias nws yog tus yuam sij rov ua dua tshiab ntawm txhua hom (piv txwv li iButton nrog cov npe tshiab ntawm cov yuam sij los khaws ntawm EEPROM sab hauv). Nws yuav tshuaj xyuas yog tias ibutton raug tso cai rov ua haujlwm sab hauv EEPROM tab sis tshuaj xyuas nws qhov chaws pov thawj tseeb. (Qhov no tau teeb tsa rau hauv iButton los ntawm USB programmer thiab qhov no koj hloov tsis tau - saib nplooj ntawv kawg rau cov ntaub ntawv). Yog tias iButton raug tso cai ua haujlwm sab hauv EEPROM, LED yuav nyem ntsuab/Txiv kab ntxwv thiab tom qab ntawd microprocessor yuav rub txhua tus lej-tus lej tawm ntawm iButton thiab khaws cia rau hauv nws EEPROM sab hauv. Qhov no yuav ua rau LED flicker thiab tuaj yeem siv sijhawm ntev txog 20 vib nas this - tsis txhob tshem tus yuam sij thaum qhov no tshwm sim. Cov LEDS yuav tom qab ntsuab ntsuab los qhia qhov kev ua haujlwm tiav - tam sim no tshem tawm iButton.
