Umdwelisi nkqubo PIC: inkcazelo, isixhobo isiqu

PIC-microcontrollers eziveliswa yinkampani American Microchip Technology Inc. Ufinyezo PIC ithetha umlawuli interface peripheral. PIC-microcontrollers kagesi abasebenzisi EPROM ehlelwe. Bona luphawulwa ukusetyenziswa encinci ngamandla, umsebenzi omkhulu, ephuhliswe kakuhle RISC-lwezakhiwo, ukuphelela functional, imilinganiselo ubuncinane kunye namaxabiso aphantsi. Microcontroller Firmware ikhutshwa phandle usebenzisa isixhobo ezifana PIC Ndingumqondisi.

incazelo

Kuba ngokoqobo chips enjalo umsebenzisi ufuna i izixhobo ezifikelelekayo azibizi. Kukho izisombululo ezininzi zobugcisa izixhobo ezifana (zombini engahlawulwayo kunye koguqulelo). Kweli nqaku siza kukhangela PIC lwenkqubo ngokwanelisayo elula, yaphuhliswa Microchip Technology Inc. Kufuneka kuqatshelwe ukuba, ngokungafaniyo izixhobo andilociko ngcono, le divaysi kwe debugger ngokupheleleyo, oko ibe inani imisebenzi eyongezelelweyo analizatorskih.

Umdwelisi nkqubo PIC-isilawuli isekelwe chip PIC18F2550 ukuxhasa USB 2.0 umsebenzi. Umphathi wesekethe ufumana umbane ukusuka Isidibanisi USB kunye, ngokufanelekileyo, akunyanzelekanga ukuba umthombo wamandla. Ngalo eli zibuko, ungavuselela nj firmware. PIC umdwelisi nkqubo ineenkalo ezincinane lulonke kwaye yenzelwe nje fob engundoqo. Kwi umzimba kukho LED ezintathu ezibonisa indlela yokusebenza yesixhobo, kunye kwiindawo zokubeka ezimbini: omnye loqhakamshelwano ikhompyutha siqu, kwaye eyesibini - ngqo kwi microcontroller.

Le uhlelo PIC kuba-kwisekethe iinkqubo kunye lwenye ye ezininzi iinkampani chip "microchip". Esi sixhobo isebenza ngokwabo, inkqubo iqokobhe okanye bayo, okanye isoftwe MPLAB IDE. Kwimeko yokuqala (sebenzisa PICkit 2 wenkqubo) icebo inokuba ukucima, qinisekisa inkumbulo wabeka ikhowudi yokhuseleko unotsheluza, hlela imixholo microcontrollers. Kwaye ukuba abhale iinkcukacha ngendlela chip kwimemori, faka i abaqhubi kunye Keeloq izitshixo. Ukongeza kwezi imisebenzi esisiseko, uhlelo unakho ukudala ixabiso izixhobo PIC ombane ku ezahlukene volts 2.5 ukuya kwezi-5, kunye 0.1 inyathelo B.

amathuba

Nale ndawo, kuba kunokwenzeka ukuba isiphene yamacebo kuphuhliswa ngaphandle zokuqhawula evela Ndingumqondisi. Izixhobo ivumela nezibuko USB ukuba akhuphe nge eliyimali yangoku 100 Ma, ukuba eli nani ligqithe, umphathi wesekethe uya ngokuzenzekelayo vala. Kwakhona, lo wenkqubo uyakwazi uyenze le ombane USB-izibuko ibhasi ngenxa icebo inokuba kunikwa ixabiso ombane yangoku. Oku kunempembelelo entle emsebenzini wakhe. Izixhobo ukuba i ukufakelwa kwayo yangaphandle, ilingana senkqubo yolawulo ukubetha avumele ukufakelwa microcontroller. Kwi inkqubo iqokobhe Tools menu, ungenza ukubaleka ukhetho Sebenzisa VPPFirst Inkqubo Ilam, microcontrollers ezifunekayo, uqwalaselo leyo awuvumeli ukuba angene imo kweenkqubo.

isiphelo

Izincomo PIC umdwelisi nkqubo yindlela enamandla, isixhobo isebenziseka ngokususa "microchip" microcontrollers. Ine- ixabiso efikelelekayo, kwaye ukuba oyifunayo, kube lula phindwa, ngenxa namaxwebhu enikwe kwi website inkampani.
