Rorohiko Pic: whakaahuatanga, pūrere ti'araa

Pic-microcontrollers whakaputaina e te kamupene American Microchip Technology Inc. Whakarāpopototanga Pic tikanga he pūmana atanga piringa. He electrically Pic-microcontrollers kaiwhakamahi EPROM programmable. E āhuatanga ratou i te kohi iti mana, mahi nui, pai whakawhanakehia-RISC-hoahoanga, kakató mahi, ngā āhuatanga iti, me utu iti. kawea Microcontroller Pūmanawa i roto i te whakamahi i te pūrere pērā i te Pic kaihātepe.

whakaahuatanga

Hoki te whakamahi mahi o taua maramara me te kaiwhakamahi i te taputapu utu, me te ngāwari. He maha rongoā hangarau taua pūrere (e rua runaruna me putanga arumoni). I roto i tēnei tuhinga ka titiro tatou ki te Pic hōtaka tika ohie, whakawhanakehia e Microchip Technology Inc. Me kï reira e, pērā i te whakaaro runaruna improvised, tenei pūrere ko te kaipatuiro tonu, reira hoki he maha o atu mahi analizatorskih kua.

e hāngai ana rorohiko Pic-pūmana te i runga i te maramara PIC18F2550 ki te tautoko i USB 2.0 mahi. Ka whiwhi te ara iahiko o nāianei hiko i te tūhono USB me, runga i, e kore e rapua e pūtake mana atu. Na roto i tenei tauranga, ka taea e koe te whakahōu i te maramara mārō. He Pic rorohiko āhuatanga iti whānui, me te te hangaia rite te fob matua. I runga i te tinana i reira e toru LED e tohu i te aratau whakahaere o te pūrere, a e rua i'ai: kotahi hoki tūhono ki te rorohiko whaiaro, me te tuarua - tika ki te microcontroller.

Tenei rorohiko Pic hoki i roto i-ara iahiko hōtaka me te patuiro o te nuinga o ngā kamupene maramara "microchip". Rere ana tēnei pūrere i runga i ona ake, hōtaka ranei anga, te pūmanawa MPLAB IDE ranei. I roto i te take tuatahi (te whakamahi i PICkit 2 mataaro) pūrere kia ūkui, manatoko mahara whakaturia flash waehere tiaki, te whakatika i te tirotiro o microcontrollers. A ki te tuhi kōrero i roto i te maramara mahara, tāuta te taraiwa me kī Keeloq. I tua atu ki enei mahi taketake, kia whakaputa i te kaihātepe te uara o ngā pūrere Pic ngaohiko i te whānuitanga o 2.5 ki te 5 volts, ki 0.1 taahiraa B.

whai wāhitanga

Ki te tenei āhuatanga, riro te reira taea ki te patuiro te whakaaro whakawhanakehia waho momotuhia i te kaihātepe. Ko te taputapu taea te tauranga USB ki puta i roto i iti uara o nāianei ki te 100 mA, ki te nui tenei ahua te, ka tahuri aunoa i te ara iahiko atu. Ano, e taea ki te Whakatikaina te ngaohiko pahi USB-tauranga rite ai he hua o te pūrere kia whakaratohia ki te uara ngaohiko o nāianei te kaihātepe ko. Tenei te mutunga he pānga pai i runga i tona mahi. Hoki ngā pūrere he he tautuhi waho, faati'a te Uwhi mana pini papatono te tautuhi microcontroller. I runga i te hōtaka anga Utauta tahua, ka taea e koe te whakahaere i te kōwhiringa Whakamahia VPPFirst Program Tāurunga, microcontrollers hiahiatia, te whirihoranga e kore nei e tukua ki te tomo i te aratau hōtaka.

mutunga

rorohiko Pic whakaaro ko te, taputapu pūkenga kaha mō te patuiro "microchip" microcontrollers. He he utu utu, a ki te hiahiatia, e taea te ngāwari tukurua, te whakawhetai ki te ngā tuhituhinga i whakaratohia i runga i te paetukutuku kamupene.
