Usuku oluhle! Lesi sihloko sibonisa inkinga yezinzwa zomgunyathi, ukulinganiselwa kwamadivayisi akhona asebenzisa lezi zinzwa kanye nesixazululo sale nkinga.

Ngaphambi kwami, kwakubhalwe futhi ngezinzwa zomgunyathi . Umehluko wesici phakathi kwezinzwa zomgunyathi nezangempela:
- Inzwa, ngisho noma ixhunywe eduze, iphendula ngemodi yamandla e-parasitic ngokungaqinisekile, njalo ngemva kwesikhashana.
- Kumodi yamandla ezinambuzane, izinga eliphezulu lithatha isikhathi eside kakhulu ukululama (ungalilinganisa nge-microcontroller noma ubuke i-oscillogram)
- ukusetshenziswa kwamanje kuphakeme kakhulu kunama-microamp amaningana (i-GND ne-VCC ukuze isuse, i-DQ nge-microammeter ukuya ku- +5 volts)
- Ngemva kwenqubo yokubala (0xF0), izinzwa aziwuphenduli umyalo wokufunda we-scratchpad (0xBE)
- Izinga lokushisa elifundwa ku-scratchpad ngemva kokusetshenziswa kwamandla ngaphandle komyalo wokulinganisa liyahluka kumadigri angu-85,0.
- Amanani we-scratchpad ezikhundleni 5 no-7 awahambisani no-0xFF kanye no-0x10
- Amanani okushisa (ezindaweni ezimbili zokuqala ze-scratchpad) afundiwe ngemva kokuvula okokuqala kwenzwa engaphelelwa amandla ngaphandle komyalo wokulinganisa onikezwe ngaphambilini abuyisela inani langaphambilini, hhayi u-50 05 (85.0 degrees).
Ngeshwa, anginayo i-oscilloscope, futhi i-Galileosky BaseBlock Lite GPS tracker isebenze njengebhentshi lokuhlola.
Izinzwa zathengwa kubathengisi abahlukahlukene, futhi iqoqo elilodwa kuphela elasebenza ngenxa yamandla ezinambuzane. Kwathengwa izingcezu ezi-5 kuphela kwezingu-50.
Okunye akusebenzanga ngenxa yamandla ezinambuzane nhlobo. Itheminali ayinikezi amandla angaphandle enzwa, futhi ukufakwa kwesistimu emotweni kufanele kwenziwe lula ngangokunokwenzeka.
Ukuxazulula izinkinga
Ngakho-ke, izinzwa zithengiwe, kodwa iqoqo elilodwa kuphela elisebenze kahle, futhi uphenyo nokuhleleka kweqoqo elisha bekuzothatha isikhathi esikahle, futhi bekungaholela ekwenyukeni kwezindleko. Ngakho-ke, inkinga kwadingeka ixazululwe iyodwa.
Njengoba kusetshenziswa isifunda esinezintambo ezimbili kuphela, kuyadingeka ukuhlela ukunikezwa kwamandla ku-sensor kusuka kucingo lwesignali, okungukuthi, ukuhlela amandla e-parasitic. Ngihlele amandla e-parasitic ngohlelo olulandelayo:
Kulolu hlelo, ukusebenza kwamandla e-parasitic kuyathuthukiswa, kodwa ngesikhathi esifanayo, kuhlale kungenzeka ukuxhuma amandla angaphandle. Kulokhu, umdwebo wokuxhuma ushintsha kancane: uma uxhuma ngamandla e-parasitic, ucingo lwe-Vcc ayisetshenzisiwe.
Ngemva kokuhlanganisa isifunda ngokukhweza phezulu, inzwa itholwe itheminali enomthamo we-capacitor ongu-1 µF. Ukuze kusetshenziswe ngobuningi, amabhodi anephaneli anamabhodi wamandla ezinambuzane aklanywa futhi ayalwa:
Iphuzu elithokozisayo: Abakhiqizi bangasebenzisa i-adhesive encibilikayo eshisayo noma i-silicone ukuze bavale inzwa. Esimweni sokuqala, ungakwazi ukushisa umkhono, ususe inzwa, ufake ibhodi, uyibuyisele emkhonweni bese uyigcwalisa ngeglue elishisayo. Esimweni sesibili, lokhu ngeke kusasebenza, futhi kwadingeka ngithengise ibhodi eduze kwenzwa, ngigcwalise nge-glue eshisayo futhi ngifake ukushisa kokushisa, ngenxa yalokho kubukeka kanje:
isiphetho
Lapha ngithanda ukunxusa abakhiqizi bemishini ukuthi bacabangele leli phuzu emikhiqizweni yabo, futhi abathengisi ukuthi bahlole izinzwa ngaphambi kokuthengisa noma bangabhekani nomphakeli nhlobo uma behlinzeka ngezinzwa zomgunyathi, futhi abasebenzisi bagqamise lesi sihloko kumazwana, ezincwadini. noma izicelo.
