Esi sikhokelo sinikezela ngenkcazo eneenkcukacha ze-8051 intetho yesincoko, ukugubungela ukusebenza, isimo, izicelo ezisebenzayo, kunye nemiceli mngeni enokubakho. Siza kuphonononga indlela yokuphumelela ngokufanelekileyo le ncwadi ibalulekileyo kwiinkqubo ezahlukeneyo ezingenayo, inika imizekelo esebenzayo kunye neengcebiso zokulungisa ingxaki. Funda ukuba ungabizi njani ngaphandle kwe-spihlores ye-PI ngeeprojekthi zakho ezingama-805 zomzimba.
The Serial Peripheral Interface (SPI) is a synchronous, full-duplex communication bus commonly used to connect microcontrollers like the 8051 to peripheral devices such as sensors, ADCs, DACs, and memory chips. Iindlela zonxibelelwano ezingathandekiyo, i-SPI ixhomekeke kwi-Clock Sign Ukulungelelanisa ukuhanjiswa kwedatha, ukuqinisekisa ukutshintshiselana ngedatha ethembekileyo. Eqhelekileyo I-80511 intetho yesidima seSPI Kubandakanya imigca emine: Mosi (inkosi ifakiwe ngaphakathi), mis (i-Missi (i-SCS (i-SCS (ikhoboka (ikhoboka likhethiweyo). Isixhobo senkosi (ihlala ilawula i-8051) ilawula iwotshi kwaye inyule isixhobo sekhoboka sisebenzisa umgca we-SS.
Iirejista ezithile ze I-80511 intetho yesidima seSPI iyahluka ngokuxhomekeke kwi-microconther yoyilo kunye noMvelisi. Nangona kunjalo, iiseti eziqhelekileyo zibandakanya i-clock polared (i-CPOL), iSigaba seClock Uqwalaselo olufanelekileyo kubalulekile ekusekeni unxibelelwano oluthembekileyo. Nxibelelana nedatha yakho ye-hicrocontlar ye-hicrocontheet yengcaciso eneenkcukacha.
Ukuphunyezwa kwesoftware kubandakanya ikhowudi yokubhala ukuze uqwalasele i-PI PAPEAL, Thumela kwaye ufumane idatha, kwaye usombulule iimpazamo ezinokubakho. Oku kubandakanya ukubeka amaxabiso afanelekileyo kwiirejista zolawulo spi kunye nokusebenzisa iindlela ze-bing-bing zodluliselwa kwedatha okanye ukusebenzisa i-microcontrollen eyakhiwe-ye-SPI yokuphathwa kwedatha efanelekileyo. Apha ngezantsi kukho umzekelo womsebenzi olula c wokuthumela idatha nge I-80511 intetho yesidima seSPI. Qaphela ukuba amagama erejista ethile aya kwahluka ngokwe-microcontroller yakho:
I-void spi_send_byte (1 << MSTR); // ukwenza i-SPI kwaye kusekwe njenge-spdr = idatha; // Idatha yomthwalo kwirejista yedatha ye-SPI ngelixa (! (I-SPSR & (1 Ngqwalaselo yeHardware
Unxibelelwano olufanelekileyo lwe-Hardware lubalulekile ekusebenzeni I-80511 intetho yesidima seSPI. Qinisekisa ukuba uMesi, Mis, i-Sck, kunye ne-SS imigca ityhutywe ngokuchanekileyo phakathi kwe-microcontroller kunye nesixhobo se-Pipheral. Nikela ingqalelo kwicala lamanqanaba ee-voltage kunye nengqibelelo yomqondiso ukuthintela urhwaphilizo lwedatha. Cinga ukusebenzisa ukupakisha okufanelekileyo okanye ukuphinda-phinda abayekiweyo apho kufanelekileyo.
Izicelo eziSebenzayo kunye nemizekelo
Ukuqhagamshela i-adc
Isicelo esinye esiqhelekileyo se I-80511 intetho yesidima seSPI Kukuqhagamshela i-Analog-to-Digital Converter (i-ADC). Uninzi lwee-ADCs Gxila unxibelelwano lwe-SPI, ivumela i-8051 yokufunda amaxabiso e-Analog. I I-80511 intetho yesidima seSPI Inika indlela elula yokufumana ezixabiso ze-analog kuluhlu olukhulu lwezicelo.
Ukunxibelelana nezixhobo zememori
Imemori ye-SPI kunye nee-chips ze-EEPROM zisetyenziswa ngokubanzi kwiinkqubo ezifakelweyo ukuze zigcinwe idatha.
