Unicode PIC: incazelo, kudivayisi isiqu

PIC-microcontrollers ezivezwa inkampani American Microchip Technology Inc. Isifinyezo PIC kusho neuropathy esibonakalayo isilawuli. PIC-microcontrollers kukhona kagesi ehlelwe abasebenzisi EPROM. Basuke izimpawu sakugcina amandla ukusetshenziswa, ukusebenza high, evuthiwe RISC-izakhiwo, ukuphelela obusebenzayo, Ubukhulu okungenani kanye namanani aphansi. Microcontroller Firmware Kwenziwa usebenzisa idivayisi ezifana PIC uMklami.

incazelo

Ukuze isetshenziswe esisebenzayo chips ezifana umsebenzisi idinga amathuluzi ezingabizi futhi engabizi. Kukhona izixazululo eziningi lobuchwepheshe mishini (kokubili amateur version commercial). Kulesi sihloko sizohlola izinhlelo PIC kahle elula, akhiwa Microchip Technology Inc. Kufanele kuqashelwe ukuthi, ngokungafani amadivayisi amateur ngokurhaba, kule divayisi kuyinto senkinga egcwele, libuye libe eziningana ezengeziwe imisebenzi analizatorskih.

Unicode PIC-isilawuli kusekelwe chip PIC18F2550 ukusekela USB 2.0 umsebenzi. Isifunda uthola kagesi kusukela isixhumi USB futhi efanele, akudingi ezengeziwe amandla umthombo. Ngalesi port, ungabuyekeza chip firmware. PIC uMklami unamahlangothi encane jikelele futhi yakhelwe njengoba Fob ukhiye. On umzimba kukhona LED ezintathu ezibonisa imodi yokusebenzisa yedivaysi, futhi Slots ezimbili: oyedwa yokuxhuma ikhompyutha siqu, kanti eyesibili - ngqo microcontroller.

Lokhu uMklami PIC ngoba e-wesifunda izinhlelo futhi ilungise inkinga izinkampani kakhulu chip "microchip". Le divayisi ugijima on siqu, noma noHlelo igobolondo, noma isofthiwe MPLAB IDE. Esimweni sokuqala (zisebenzisa PICkit 2 Programmer) cingo lungase ukusula, ukuqinisekisa imemori setha ikhodi Ukuvikelwa flash, hlela okuqukethwe microcontrollers. Futhi ukurekhoda ulwazi kucezu inkumbulo, ukufaka abashayeli futhi Keeloq okhiye. Ngaphezu kwalezi imisebenzi eyisisekelo, uMklami angase ukhiqize ukubaluleka amadivayisi PIC voltage ku ezahlukene 2.5 kuya 5 volts, ne 0.1 isinyathelo B.

amathuba

Nge lesi sici, kuba nokwenzeka Debug amadivaysi ezakhiwa ngaphandle Unqamula kusuka uMklami. I-apharathasi ivumela echwebeni USB ukukhipha ngokusebenzisa okuzisholo Inani lamanje kuya ku-100 ma, uma leli nani liphindeke kudlulwe, circuit ngeke ngokuzenzakalelayo cisha. Futhi, uhlelo uyakwazi ulinganise voltage-USB port ibhasi njengoba kungase yalokho zedivayisi ihlinzekwe kumuntu zamanje voltage value. Lokhu ekugcineni kuba nomphumela omuhle emsebenzini wakhe. For Amadivayisi nokuba yokusetha kabusha zangaphandle, ilingana izinhlelo ishayela control evumela reset microcontroller. On uhlelo Amathuluzi imenyu igobolondo, ungakwazi ukusebenzisa ukhetho Sebenzisa VPPFirst Uhlelo Ukungena, microcontrollers kudingeka, ukucushwa okuyinto ayikuvumeli ukungena imodi izinhlelo.

isiphetho

Kubhekwe PIC uMklami elinamandla, ithuluzi enemisebenzi iziphazamiso "microchip" microcontrollers. It has an ngentengo eqolo, futhi uma uthanda, kungenziwa kalula ngokuphindaphindiwe, sibonga imibhalo enikeziwe kwi-website yenkampani.
