• Inyathelo lesi-3: Izixhobo zidibanisa usebenzisa ubuncinane imigca emine yonxibelelwano: SCLK, MOSI, MISO kunye neSS. I-SCLK yilayini yewotshi engqamanisa ukuhanjiswa kwedatha. I-MOSI ithumela idatha esuka kwinkosi ukuya kwikhoboka, ngelixa i-MISO ithumela idatha esuka kwikhoboka ukuya kwinkosi. I-SS, okanye i-Slave Select, isetyenziselwa ukukhetha ukuba leliphi ikhoboka elinxibelelanayo.
• Inyathelo lesi-4: Unxibelelwano kwi-SPI lusekwe kwi-8-bit data transmissions. Idatha ihanjiswa ngokulandelelana, kancinci kancinci, ngolandelelwano oluthile.
• Inyathelo lesi-5: Izinga le-baud kwi-SPI lichongwa ngokumisela i-clock frequency kwi-master. Isantya sinokuhlengahlengiswa ukuze sihambelane neemfuno zenkqubo, kodwa kufuneka kuvunyelwane phakathi kwenkosi nekhoboka.
• Inyathelo lesi-6: Enye yeenzuzo eziphambili ze-SPI interface kukuguquguquka kwayo. Ivumela ulungelelwaniso lwebhasi yedatha, oko kuthetha ukuba Amakhoboka amaninzi anokunxibelelana nebhasi enye.
• Inyathelo lesi-7: Kubalulekile ukuqaphela ukuba ujongano lweSPI aluboneleli ngempazamo okanye iindlela zokuphatha ukungqubana kwedatha. Oku kufuneka kulawulwe kwinqanaba lesicelo.
• Inyathelo lesi-8: Ujongano lweSPI lusetyenziswa kwiintlobo ngeentlobo zezicelo, ezinje inkumbulo yefleshi, abenzi boluvo, iiperipherals kunye nokunye. Kubaluleke kakhulu kwiinkqubo ezifakwe kuyo apho kufuneka unxibelelwano olukhawulezayo, oluthembekileyo.

Imibuzo neempendulo

Imibuzo kunye neempendulo malunga "nokuqonda ujongano lweSPI?"

1. Yintoni iSPI interface?

I-SPI (i-Serial Peripheral Interface) i-interface yonxibelelwano yiprotocol yonxibelelwano oluhambelanayo.
