Amasuntswana u-0 kunye no-1 alawula ubude begama kwaye avumele ubude begama ukusuka kwisi-5 ukuya kwisi-8. Iisetingi zebit zitsalwa ngokuthabatha i-5 kubude begama elifunekayo. I-Bit yesi-2 imisela inani leendawo zokumisa. Kunokubakho enye okanye ezimbini zokumisa amasuntswana. Ukuba iBit 2 imiselwe ku-0, kuyakubakho isingxungxo esinye. Ukuba iBit 2 isetelwe ku-1, kuyakubakho amasuntswana okumisa amabini. Amasuntswana 3 ukuya 6 ulawulo ukulingana kunye nekhefu vumela. Aziqhelekanga ukusetyenziswa kunxibelelwano kwaye kufuneka zimiselwe ku-zero. I-Bit 7 yi-DLAB exoxwe ngayo ngaphambili. Kufuneka imiselwe ku-zero emva kokuba isahluli silayishiwe okanye kungenjalo akuyi kubakho lunxibelelwano.
Umyalelo we-C wokuseta i-UART ye-8-bit yegama, akukho mlinganiso, kunye nentwana yokumisa ithi:
ngaphandle (BASEADDR +3, 0x03)

Inyathelo lokugqibela lokuqalisa kukugungxula ii-buffers zomamkeli. Ukwenza oku ngokufunda kabini kwi-buffer yomamkeli kwidilesi yeSiseko +0. Xa yenziwe, i-UART ikulungele ukusetyenziswa.

Ulwamkelo
Ulwamkelo lunokusingathwa ngeendlela ezimbini: ukuvota kunye nokuqhutywa kokuphazamiseka. Xa kuvotwa, ulwamkelo lufezekiswa ngokufunda rhoqo iRejista yeSimo somgca kwidilesi yeSiseko +5. I-Bit 0 yale rejista ibekwe phezulu xa idatha ilungele ukufundwa kwi-chip. I-loop yokuvota elula kufuneka ihlolisise le bit kwaye ifunde idatha njengoko ifumaneka. Iqhekeza lekhowudi ilandelayo lisebenzisa i-polling loop kwaye isebenzisa ixabiso le-13, (i-ASCII Carriage Return) njengemakishi yokuphela kokudluliselwa:

Unxibelelwano oluqhutywa luphazamiseko kufuneka lusetyenziswe xa kunokwenzeka kwaye lufuneka kumazinga aphezulu edatha. Ukubhala umamkeli oqhutywa sisiphazamiso akukho nto intsonkothileyo kunokubhala umamkeli ovunyiweyo kodwa kufuneka kuthathelwe ingqalelo xa ufaka okanye ususa isiphazamiso sakho ukuphepha ukubhala uphazamiseko olungalunganga, ukuvala uphazamiseko olungalunganga, okanye ukucima ukuphazamisa ixesha elide kakhulu.
Umphathi uya kuqala afunde iRejista yoPhakamiso yokuchonga kwidilesi esisiseko +2. Ukuba isiphazamiso sesokuFumana iDatha eFumanekileyo, umlawuli ngoko ufunda idatha. Ukuba akukho siphazamiso silindileyo, ulawulo luphuma kwindlela yesiqhelo. A sample handler, ebhalwe ngo-C, imi ngolu hlobo lulandelayo:

Ugqithiso

Ugqithiso lwe-RS485 kulula ukulusebenzisa. Isici se-AUTO kwimodi ye-RS485 ngokuzenzekelayo yenza umthumeli xa idatha ilungele ukuthumela, ngoko akukho mfuneko yesoftware. Le software ilandelayo example yeyokusebenza okungeyo-AUTO kwimo ye-RS422. Okokuqala umgca we-RTS kufuneka ubekwe phezulu ngokubhala i-1 ukuya kwiBit 1 yeRejista yoLawulo lweModem kwi-Base Address +4. Umgca we-RTS usetyenziselwa ukuguqula i-transceiver ukusuka kwimowudi yokwamkela ukuya kwimowudi yokuhambisa kunye nokunye.
Emva kokuba oku ngasentla kwenziwe, ikhadi likulungele ukuthumela idatha. Ukuhambisa umtya wedatha, umthumeli kufuneka aqale ajonge iBit 5 yeRejista yeSimo somgca kwidilesi yeSiseko +5. Loo ntwana yi-transmitter-ibambe-irejista- iflegi engenanto. Ukuba iphezulu, i-transmitter ithumele idatha. Inkqubo yokujonga isuntswana ide iye phezulu ilandelwe ngokubhala iyaphindwa de kungabikho datha iseleyo. Emva kokuba yonke idatha idluliselwe, i-RTS bit kufuneka ihlaziywe ngokubhala i-0 kwi-Bit 1 yeRejista yoLawulo lweModem.

Iqhekeza lekhowudi i-C lilandelayo libonisa le nkqubo:

Isilumkiso
I-OUT2 bit ye-UART kufuneka isetwe 'YINYANISO' kunxibelelwano olululo oluluphazamiseko oluqhutywayo. Isoftware yelifa isebenzisa le bit ukuphazamisa isango kwaye ikhadi lisenokunganxibelelani ukuba bit 3 yerejista 4 (iRejista yoLawulo lweModem) ayimiselwanga.

Oku kuyinyani nakwi-RS422 kodwa i-RS485 ibonelela ngazo zonke izibonelelo ze-RS422 plus ivumela izixhobo eziya kuthi ga kwi-32 ukwabelana ngezibini ezijijekileyo ezifanayo. Ngaphandle koku kungasentla kukuba izixhobo ezininzi zeRS422 zinokubelana ngentambo enye ukuba inye kuphela eya kuthetha kwaye abanye baya kuhlala befumana.

Imiqondiso eyahluka-hlukeneyo elungeleleneyo

Isizathu sokuba izixhobo ze-RS422 kunye ne-RS485 zinokuqhuba imigca emide ngokugonywa kwengxolo ngaphezulu kwezixhobo ze-RS232 kukuba kusetyenziswa indlela yokudibanisa umahluko olinganayo. Kwinkqubo yolwahlulo olulungelelanisiweyo, umqulutage eveliswe ngumqhubi ibonakala ngapha kweperi yeengcingo. Umqhubi womgca olungelelanisiweyo uya kuvelisa ivolthi eyahlukileyotage ukusuka +2 ukuya +6 volts ngapha kweetheminali zayo zokuphuma. Umqhubi womgca olungelelanisiweyo unokuba negalelo elithi "vumela" isignali edibanisa umqhubi kwii-terminals zayo zokuphuma. Ukuba isignali "yenza" icimile, umqhubi uyanqanyulwa kumgca wothumelo. Le meko iqhawukileyo okanye ekhubazekileyo idla ngokubizwa ngokuba yimeko ye-"tristate" kwaye imele i-impedance ephezulu. Abaqhubi be-RS485 kufuneka babe nalo buchule bokulawula. Abaqhubi be-RS422 banokuba nolu lawulo kodwa alusoloko lufuneka. Umamkeli womgca womahluko olungelelanisiweyo uva umqulutagimo yelayini yothumelo ngapha kwemigca emibini yegalelo lomqondiso. Ukuba umahluko voltagI-e inkulu kuno +200 mV, umamkeli uya kubonelela ngemeko ethile yengqiqo kwimveliso yayo. Ukuba umahluko voltagigalelo le-e lingaphantsi kwe -200 mV, umamkeli uya kubonelela ngemeko yengqiqo echaseneyo kwimveliso yayo. Umthamo omkhulu wokusebenzatagUluhlu lwe-e lusuka ku +6V ukuya ku-6V luvumela umthamotagukuthotywa okunokuthi kwenzeke kwiintambo zothumelo ezinde.

Ubuninzi bemowudi eqhelekileyo voltage rating of + 7V inika ukhuseleko ingxolo elungileyo ukusuka voltages ifakwe kwimigca ejijekileyo. Uqhagamshelo lomgca osezantsi wesignali luyimfuneko ukuze kugcinwe imowudi eqhelekileyo voltage kuloluhlu. Isekethe inokusebenza ngaphandle koxhumo lomhlaba kodwa ayinakuthenjwa.
