riro te reira i nui noa atu te rongonui kaupapa hoahoa hiko. whakahere matou ki tou whakarongo i te tuhinga e ka korero koe he aha te hōtaka microcontrollers mō tīmata.
He aha e microcontrollers reira?
Tuatahi o te katoa, e hiahia ana koe ki te whakaahua i te āhuatanga ki te microcontrollers. Ko te meka e whakaputaina ratou kahore tetahi u, engari e rave rahi, na reira ko te rota tonu o microcontrollers rerekē, e whai tautuhinga rerekē, ngā āhuatanga rerekē o te whakamahi, me te ngā taea. rerekē ratou i roto i te tere mahi, atanga atu, me te maha o körere. Ko te tino rongonui puta noa i te mua Soviet Union he māngai RІS me AVR. He ngāwari, i whakarite ratou rongonui Papatonotanga AVR me RІS.
Ka rite ki e programmed microcontrollers?
kawea Programming microcontrollers te i roto i, te nuinga ki te awhina o whakaaro motuhake, ka karanga hötaka. Ka taea e hötaka hei whaiaro-hanga hokona ranei ranei. Otiia ka te mārō microcontroller te whakamahi i te tupono kaihātepe kāinga e ka riro te reira i te "pereki", he tino nui. He he kotahi atu kōwhiringa e taea whakaaro e koe te tauira o te poari "Arduino". Rere ana te poari i runga i MC o Atmel, a kua mahi reira hōtaka microcontrollers AVR. kē he bootloader me USB tauranga mua-nira e tukua whakamahi haumaru flash microcontroller, hoatu te uru kaiwhakamahi ki te raraunga e kia te MC pai ki te mono i te poari. e kore te mea rite uaua rite mea ai reira Programming microcontrollers mō te tīmata, me i te tetahi pūkenga me te parapara ka whakaora koe i he ki te haere mo te huarahi hou.
rerekētanga Pūmārō o microcontrollers rerekē
A, no te kōwhiri i te microcontroller kia whakarongo ki te tahi mau rerekētanga pūmārō kore e ara rerekē kamupene, a i roto i te tauira ngā taua. Hei timata ki te whakarongo ki te kaha ki te tuhirua raraunga i runga i te microcontroller. Ka tukua tenei āhuatanga ki a koe whakamātau ki tetahi MC roa. mōhio hoki te maha o titi ki ratou ūnga. Kaua e whakarere, me te auau o te karaihe e rere e te kaupapa: pānga reira te maha o ngā mahi ia tuarua, e taea te mahi i te microcontroller. I te whakamātautau o enei āhuatanga, kia rite ki te pai kia rite ki te mahara IC kia tīmatanga mea e kore e taea te mahi i tetahi mea maramarama microcontroller, engari ko te he pōhēhē tenei. Kia mahara ki e microcontrollers hōtaka mo titau tīmata te taputapu pai i te timatanga, engari ka rite ki te rahui, a ka taea e koe te tango i te tahi mea atu kaha.
Reo o microcontrollers hōtaka
whakamahia te microcontroller te rite te reo hōtaka e rua: C / C ++ me assembler. He ona huapai me ngā huakore ia o ratou. Na, ki te kōrero tatou e pā ana ki te assembler, hanga ana e ia te reira taea ki te mahi i nga mea katoa rawa minita me tika, he mea nui rawa, no te kahore koutou e whai nui RAM kaha whakahaere (e, rokohanga, he tino onge) ranei. Ko tona rangahau me te tuhituhi i runga i ngā hōtaka reira e rapu he rota o kaha, te wā, me te hora. Na reira, hoki te whanaketanga e hāngai ana i runga i microcontrollers nuitia whakamahia reo hōtaka C me C ++. E pai ake ratou i matau e te puka, me te hanganga e tata kupu tangata, ahakoa kahore ratou e tohu ia i roto i te tikanga tonu. ano i ratou i te āhuatanga tino pai-rangahaua e taea ngāwari taunekeneke ki te pūmārō, feruri e he tika he huānga o te hōtaka tenei. Hoki ona painga kitea katoa i roto i C ko C ++, te hanga i tētahi hōtaka atu e toru-ahu, nui atu i te reo whakaminenga.
Hoki, i roto i te tahi mau taime, ka whakamahia wāhi whakahaere arohaehae te, ko reira taea ki te whakakotahi i ēnei reo. Tata ki te katoa o te taiao whanaketanga mō te C me C ++ whai te kaha ki te tāuta i te hōtaka i roto i fakahū assembler. Na reira, ki te puta he raruraru i te pae tino e taea tuhituhi assembler whakauru, me te kōtuitui i te reira ki te mārō mo te microcontroller me te mārō ano, ranei, kaua, te nuinga o reira ki te tuhituhi i roto i te C C ranei ++. hōtaka Microcontroller i roto i C he māmā, pera whiriwhiri maha iwi enei reo. Ko te hunga e kore e wehi o fifi nei me te hiahia ana ki te matau i te taa o te taputapu mahi, ka taea e tamata ratou ringa, me te ki te assembler.
kupu pekanga
Ki te reira i tetahi hiahia ki te whakamātau ki te microcontrollers, he reira pai. Ka taea e anake tatou tohutohu manawanui me te manawanui, a ka katoa te whāinga whakaturia ki te aroaro o te ma'imi, ka kia whaihua. Papatono microcontrollers mō tīmata me te iwi mātanga titiro rerekē: ko reira uaua mō te tīmata, te mātanga - mahi. Ko te mea matua - kia mau i roto i te ngakau e mea katoa e kore ko e anga ke ki te ture o te ahupūngao, he whaitake, me te whakatakotoria.
