I-3 Wire Spice

Esi sikhokelo sinika isishwankathelo esibanzi se I-3-wire spi, ukuchaza ukusebenza kwayo, izibonelelo, kunye nezicelo ezisebenzayo. Siza kuzigubungela iziseko, senze ukungafani kwayo kwi-4-wire spire, kwaye uphonononge imizekelo yendalo yehlabathi. Funda ngendlela yokuphucula ngokufanelekileyo lo mgaqo-nkqubo wonxibelelwano ophela kwiiprojekthi zakho.

Ithini i-Internation ye-3-wire spire?

Ngokungafaniyo ne-4-wire spi (i-Priilial Perfayili) esebenzisa imigca emine - i-mosi (inkosi isebenza), i-miso (i-SCS (i-SCS (ikhoboka likhethiweyo) - I-3-wire spi Ukushiya ilayini (i-SS) yomgca. Oku kwenziwa lula kunciphisa ubunzima be-hardware kunye nePIN ukubala, yenzela ukuba ilungele ukusetyenziswa apho kubaluleke kakhulu izixhobo ezibalulekileyo.

Isebenza njani i-3-wiire spicielic spi?

Ukungabikho komgca we-SS kunyanzelisa indlela eyahlukileyo yokukhetha izixhobo. Kwi I-3-wire spi, Ukukhetha izixhobo kuphakanyiswa kwezinye iindlela, ezinje:

• Idilesi yedilesi: Isixhobo ngasinye sabelwe idilesi eyahlukileyo, kwaye inkosi ikhetha isixhobo ngokudlulisela idilesi efanelekileyo ngaphambi kokudluliselwa kwedatha.
• Ukukhetha isixhobo esilungisiweyo: Kwiinkqubo ezilula, sisixhobo esinye kuphela esinokunxibelelana, sisuse imfuno yokukhetha isixhobo.
• Ulawulo lwesoftware: Isoftware inokusetyenziselwa ukuphatha ukhetho lwezixhobo olusekwe kwixesha okanye ezinye iindlela.

Imigca emithathu eseleyo (iMosi, eMiso, kunye ne-Sck) isebenza njenge-4-wire spire. Idatha idluliselwa ngokusebenzisa isitayile sewotshi (i-Sck), kunye neMosi ephethe idatha kwiNkosi kwiNkosi, kunye ne-miro ethwele idatha yeNkosi.

Izibonelelo kunye nokungalunganga kwe-3-wire spi

I I-3-wire spi inika izibonelelo ezininzi:

• Ukubalwa kwePINE Ukugcina iPIN kunokubaluleka kwizicelo ezinyanzelekileyo.
• Izixhobo ezilula: I-HARD yezixhobo ezincinci ziguqulela kwiindleko ezisezantsi kunye nokuthengiswa okuphuculweyo.
• Isantya esiphezulu (kunokubakho): Ukungabikho kolawulo lweSiboniso lwe-SS ngamanye amaxesha kunokubangela ukuba kudluliselwe idatha engaphezulu.

Nangona kunjalo, kukho izinto ezingalunganga:

• Ukukhetha isixhobo Ukumiliselwa kwezinye iindlela zokukhetha izixhobo zongeza isoftware.
• I-Scimo Elinqongopheleyo: Ukulawulwa kwezixhobo ezininzi ngaphandle kwe-SS kunokuya kulucelomngeni ngakumbi.

Izicelo ze-3-wire spi

I I-3-wire spi Fumana izicelo kwiimeko ezahlukeneyo apho ukubalwa kwePine incinci, njenge:

• Iindleko eziphantsi, iinkqubo ezingenelweyo: Apho ukusebenza ngendleko kuyinkxalabo ephambili.
• Inforsor interfacing: Ukuqhagamshela izinzwa ezilula nge-wiring encinci.
• Izixhobo zeFayile ezincinci: Imizekelo ibandakanya ukungachithi okanye iirobhothi ezincinci.

Thelekisa: I-3-Wire Spi vs. 4-wire spi

Ukuqukumbela

I I-3-wire spi Ibonisa enye indlela esebenzayo kwi-4-wire spire xa kuncitshiswa kwePIN xa kuncitshiswa kwePIN kwindawo ephambili. Ukuqonda iivesi zayo kunye nokusikelwa umda kubalulekile ekuphunyezweni ngempumelelo. Ngelixa ingenza lula izixhobo, qwalasela i-ferder malunga nokukhetha isixhobo kunye nokuhamba kwenkqubo ngokubanzi ngaphambi kokuthatha iprojekthi yakho.

I-LCD ekumgangatho ophezulu ye-LCD kunye nezinto ezinxulumene noko, cinga ukukhangela iminikelo ye I-Dalian Mpuma ebonakalayo Co., Ltd. Banikezela ngoluhlu olubanzi lwezisombululo kwizicelo ezahlukeneyo.

¹ Olu lwazi luhlanganiswa kwizibonelelo ezahlukeneyo ezifumanekayo nolwazi ngokubanzi malunga neeprotokholi zonxibelelwano ze-SPI. Iinkcukacha ezithile zokumiliselwa zinokwahluka ngokuxhomekeka kwi-microcontroller kunye nezixhobo zomdinga.
