2024-04-25 2468

I-NRF24L01 yi-2.4G yoNxibelelwano lwe-chip ephuhliswe yiNkampani ye-Nordic.Ineempawu zokusetyenziswa kwamandla eziphantsi, iindleko eziphantsi kunye nesantya esiphezulu, kwaye zinokubonelela ngezisombululo ezingcono zokusetyenziswa kweemveliso zekhompyuter zeDesktop kunye nezixhobo ze-smart.Eli nqaku liza kuzisa kumenzi, uLwakhiwo, izicelo, iindlela zokusebenza kunye noMgaqo wokuSebenza.

I-NRF24L01 yi-monolithi entsha ye-RF yenzelwe ngokungqalileyo kwi-ISM Rinet kwi-2.4 GHZ ukuya kwi-2,5 GHz.Idibanisa iimodyuli ezininzi ezisebenzayo ezinjenge-crysstillator, i-frequency ye-frequency, i-Amplifier, kunye neMUPILISIR, kunye neMvumelwano yeTockarest.Nge-spi umfanekiso we-SPI, i-NRF24L01 inokunxibelelana ne-5V microcontroller, ukuze amandla okukhutshelwa, ukukhetha i-Channel kunye noSeto lweProtol kungamiselwa nge-spices umfanekiso we-SPI.Oku kuthetha ukuba i-NRF24L01 ingaqhagamshelwa phantse kuzo zonke iintlobo ze-chips ze-microthroller ukufikelela kwimisebenzi yokuhambisa idatha engenazingcingo.

I-NRF24L01 yenziwa ngu-Norde Comicondcuctor.I-Nordic Semicondtuctor, ebizwa ngokuba nguNordic vlsi, yinkampani ye-semicondus ye-semiconductor.Inkampani isebenza ngokhethekileyo kwi-Urtra-On-Onal Doory Spiness Spidies-On-On-On-On-On-On-On-On-On-On-On-On-On-On-Chip kunye neeDilesi ze-GHZ kwi-2.4 GHZ I-Ism I-Ism, ngokusetyenziswa kwamandla kunye neendleko eziphambili ekugxilwe kuzo kunye neendleko ezixabisekileyo.Izicelo zomsebenzisi we-semic semicondcuctor zizinto ezingenazingcingo zentambo, iimpuku ze-wices, ezonyango ezingenazingcingo, izicelo zomdlalo we-Smart, ezifana nelizwi kwi-IP), ukhuseleko, kunye neethoyi.

Umzobo webhlokhi weNRF24L01 uboniswe apha ngasentla.Ukusuka kwimbono yolawulo lwe-microcontrontroller, kufuneka sifuneke kuthi

-Iintloko ze-voip

-I-rfid esebenzayo

- Abalawuli bomdlalo

-Iingcingo zePC ezingenazingcingo

-Imidlalo yezemidlalo kunye nezinzwa

-Iinkqubo zokulandela iiasethi

-Imouse, iitshixo zekhibhodi, kunye neeMkhupheleni

-Iinethiwekhi ze-Ultra-ephantsi

- Ikhaya kunye nentengiso ezenzekelayo

-Iziko leMidiya leMidiya

-Ulawulo olude kakhulu kwi-elektroniki yabathengi

Ii-NRF24l01 zonxibelelwano kufuneka zifezekise ezi meko zintathu zilandelayo:

-Iziteshi ziyafana (zetha irejista yesitishi i-rf_ch).

-Iidilesi ziyafana (Seta i-tx_addr kunye ne-rx_addr_po efanayo).

-Umanani ee-Byte athunyelwe kwaye wafumana ixesha ngalinye lifana (ukuba ububanzi bedatha esebenzayo yejelo lusetwe kwi-N, emva koko inani lee-Byte lithunyelwe nakwexesha ngalinye kufuneka libe no-n, kunjalo, n<=32).

Imodyuli yonxibelelwano ye-NRF24L ye-wireless ye-wireless inokusetwa ngeendlela ezahlukeneyo zomsebenzi, kubandakanya nemodi yamandla, imowudi yokulinda, kunye nemowudi yendlela yedatha.Imisebenzi kunye nokusebenza kwemowudi nganye imi ngolu hlobo lulandelayo.

Kwimowudi ephantsi, umsebenzi ngamnye we-NRF24l01 ucinyiwe ukugcina ukusetyenziswa kwangoku.Emva kokungena kwimodi ephantsi yamandla, i-NRF24L01 iyasebenza ukusebenza, kodwa irejista ihlale ingaguqukanga.Imowudi yamandla elawulwa yi-pwr_up incinci kwirejista.

Imowudi yokulinda ndinciphisa i-avareji yenkqubo yangoku ngelixa iqinisekisa ukuqala ngokukhawuleza.Kwimo yokulinda i, i-crystal isebenza ngokuqhelekileyo.Kwimowudi yokulinda ii, ezinye ze-uffers zewotshi zikwindlela yokusebenza.Xa irejista ye-TX ye-TIFO kwicala lokudlulisela ingenanto kwaye i-CE iphezulu, ingena kwimodi yokulinda II.Ngexesha lemowudi yokulinda, imixholo ye-rereretay yoqwalaselo lwamagama ahlala engaguqukanga.

I-NRF24L yeendlela zokulungisa zepakethi zepakethi zibandakanya indlela ye-shockarst kunye nendlela ephuculweyo ye-shockarst.

Imowudi ye-shockarst, i-NRF24L01 inokudityaniswa kwixabiso eliphantsi le-Mcu.Inkqubo yokuqhubela phambili isantya sesantya esiphezulu ilawulwa yi-RF yangaphakathi ye-RF, ngelixa usulelo lwedatha lwenziwa nge-spi yobungqina be-SPI kwinqanaba le-Mcu ngokwayo.Imowudi ye-shockarst inciphisa umndilili ophakathi wokusebenzisa unxibelelwano ngokuvumela unxibelelwano lwesantya esiphantsi kunye ne-MCU ngelixa igcina unxibelelwano oluphezulu kwicandelo elingenazingcingo.

Imowudi ephuculweyo ye-Shockarst yenza ukuba ukwenziwa kwemigaqo yendlela ezimbini zendlela elula kunye nefanelekileyo.Ngendlela eqhelekileyo yokunxibelelana, umthumeli ucela isixhobo sokuphela sithumele uphawu lokuphendula emva kokufumana idatha ukuze umthumeli afumane idatha elahlekileyo.Ukuba ilahleko yedatha yenzekile, idatha elahlekileyo ifunyenwe ngumsebenzi wokubuyisa.Imowudi ephuculweyo ye-Shocburttm ilawula zombini impendulo kwaye iphinde ibuyise imisebenzi ngaphandle kokunyusa umthwalo we-MCU.

Xa sidlulisela idatha, siqala ukuqwalasela i-NRF24L01 kwimodi yokudlulisa.Okulandelayo, sibhala idilesi ye-Node ye-TX_ADDR kunye nedatha esebenzayo ye-TX_PLD kwi-Buffer yendawo ye-Buffer ye-NRF24l01 ngokulandelelana kwe-SPI ngokulandelelana.I-TX_PLD kufuneka ibhalwe ngokuqhubekayo ngelixa i-CSn iphantsi, ngelixa i-TX_ADDR kufuneka ibhaliwe kube kanye xa idluliselwa.Emva koko, simisele i-CEE eceke kwaye siyibambe kakhulu kwii-microsecond ezili-10, emva koko iqale ukuhambisa idatha emva kokulibaziseka kwe-130 microsecond.Ukuba impendulo ye-Auto-inikwe amandla, i-NRF24L01 iya kungena kwimodi yokufumana ngokukhawuleza emva kokudlulisela idatha yokufumana uphawu lokuvuma (impendulo yempendulo efunyenweyo kufuneka ihambelane nedilesi ye-tx_addr).Ukuba impendulo ifunyenwe, unxibelelwano lujongwa njengempumelelo, iflegi ye-TX_DS iya kusetshwa, kwaye i-TX_PLD iya kucocwa kwi-TX FIFO.Ukuba akukho mpendulo ifunyenweyo, i-NRF24L01 iya kuyibuyisa ngokuzenzekelayo idatha (ukuba i-reporanshini yokubuyiselwa ngokuzenzekelayo ivuliwe).Ukuba inani lokubuyisa (i-ARC) lifikelela kumda ophezulu, iflegi ye-MAX_T iya kusetshwa, kwaye idatha kwi-TX i-TIFEO iya kugcinwa ngenxa yokubuyiselwa.Xa i-max_rm okanye iflegi ye-tx_Ds isetwe, i-ITQ iya kucocwa kwaye ukuphazamiseka kuya kwenziwa ukwazisa i-MCU.Okokugqibela, ukuba ugqithiso luyaphumelela kwaye u-CE uphantsi, i-NRF24L01 ingena kwi-IDle ye-IDle 1. Ukuba kukho idatha kwi-STAT STACK kwaye iphezulu, faka usulelo olulandelayo.Ukuba akukho datha kwi-stack stack kunye ne-CE iphezulu, ingena kwimodi 2.

Xa sifumana idatha, siqala ukuqwalasela i-NRF24L01 kwimodi yokufumana.Emva koko kulibaziseka kwii-microsecond ezili-130 ukungena kwiLizwe elifumanayo kwaye kulinde ukufika kwedatha.Xa umamkeli efumana idilesi efanelekileyo kunye ne-CRC, igcina ipakethi yedatha kwi-RX i-RX kwaye iseta iflegi yeflegi ye-RX_Dr ephezulu, ivelisa i-MCE i-MCU ukuba ifunde idatha.Ukuba umsebenzi wokuphendula we-Auto-owenziweyo wenziwe ngeli xesha, umamkeli uya kungena kwilizwe elidlulisela ngaxeshanye kwaye athumele umqondiso wokuphendula.Okokugqibela, ukuba ulwamkela luphumelele kwaye i-DE ihamba iphantsi, i-NRF24L01 ingena kwi-Ednel Doode 1.

Okokuqala, imodyuli yemodyuli kufuneka isethwe kwisitishi esifanayo, kwaye uqiniseke ukuba ubude bemodyuli yemodyuli ilingana nobude bemodyuli yemodyuli B. Ke, siqwalasele imodyuli yemodyuli B.Okulandelayo, cwangcisa idilesi yemodyuli yemodyuli ukuba yeyongeza i-bodrr_b, ke loo modyuli B inokufumana idatha ngokuchanekileyo xa imodyuli ithumela.

Ngapha koko, idilesi yedilesi ye-onr_b elungiselelwe imodyuli ye-B yenye kuphela yeziteshi zedatha ezininzi.Imodyuli ihlala ineendlela ezintandathu zokufumana iziteshi, ezithetha ukuba imodyuli B inokufumana idatha kwiimodyuli ezintandathu ezahlukeneyo ngexesha elinye.Ewe, imodyuli b inokuthumela idatha kuphela kuba ukuthumela idatha kwijelo elinye ngaxeshanye kunokubangela uphazamiseko.

Ukuqukumbela, i-NRF24L01 sisisombululo esinokuthenjwa ukuba ufuna ukwakha imodyuli ye-RF ephantsi ye-RF yeprojekthi yakho.Nxibelelana nathi ukuba ufuna ukucaciswa ngakumbi kwisixhobo okanye indlela yokudibanisa kwiprojekthi yakho.

Isebenzisa i-2,4 GHZ band kwaye inokusebenza ngamaxabiso e-baud ukusuka kwi-250 kbps ukuya kwi-2 Mbps.Ukuba isetyenziswe kwindawo evulekileyo kwaye inomgangatho osezantsi we-baud Uluhlu lwayo lufikelela kwiimitha ezili-100.

I-NRF24L01 yi-chip enye ye-2.4GHz Translaiver nge-protografithi ye-Baseband ye-Osegeball (ephuculweyo ye-Shocburst ™), yenzelwe izicelo ezingenazingcingo ze-Ultra.I-NRF24L01 yenzelwe ukusebenza kwiHlabathi ngokubanzi ye-Ism Rine, ibhendi ye-Ism kwi-2.400 - 2.4835ghz.

Ngokwenene bayafana, i-NRF24L01 + yinguqu ephuculweyo ye-NRF24l01 chip.I-NRF24L01 ixhasa kuphela i-1MBPS kunye nenqanaba le-2Mbps Sperch, ngelixa i-NRF24L01 + ixhasa i-250kbps zothumelo.

Kodwa ngamanye amaxesha unokufuna nje ukuthumela okanye ukufumana ngaphandle kokusebenzisa i-wifi okanye kwi-Bluetooth, kulungile ke i-NRF24L01 iya kuba lukhetho olufanelekileyo.Ngokungafaniyo nabanye basebenzisa amaza erediyo ukuba anxibelelane phakathi kweemodyuli, uhlobo olufanayo elisetyenziswe kwiifowuni ezingenantambo endlwini yakho.
