Yethula Amandla E-ATMEL MCU Boards
Imininingwane
Imemori yohlelo lwe-Flash eshumekiwe yekhwalithi ephezulu
I-Flash yekhwalithi ephezulu kulula ukuyisula nokubhala, isekela i-ISP ne-IAP, futhi ilungele ukulungisa iphutha lomkhiqizo, ukuthuthukiswa, ukukhiqizwa, nokubuyekeza.I-EEPROM eyakhelwe ngaphakathi yempilo ende ingalondoloza idatha engukhiye isikhathi eside ukuze igweme ukulahlekelwa lapho kucishwa amandla.I-RAM yomthamo omkhulu ku-chip ayikwazi ukuhlangabezana nezidingo zezikhathi ezivamile kuphela, kodwa futhi isekela ngempumelelo kakhulu ukusetshenziswa kolimi lwezinga eliphezulu ukuze kuthuthukiswe izinhlelo zesistimu, futhi inganweba i-RAM yangaphandle njenge-MCS-51 single-chip microcomputer.
Zonke izikhonkwane ze-I/O zinezinqamuleli zokudonsa ezilungisekayo
Ngale ndlela, ingahle isethwe ngayodwana njengokungenayo/okuphumayo, ingasethwa (okokuqala) i-impedance ephezulu, futhi inamandla okushayela aqinile (amadivayisi okushayela amandla angashiywa), okwenza izinsiza ze-I/O port ziguquguquke, zibe namandla, futhi isebenza ngokugcwele.sebenzisa.
Izihlukanisi zewashi ezizimele eziku-chip
Ingasetshenziselwa i-URAT, I2C, SPI ngokulandelana.Phakathi kwazo, isibali sikhathi esingu-8/16-bit sinokufinyelela ku-10-bit prescaler, futhi i-coefficient yokuhlukanisa imvamisa ingasethwa isofthiwe ukuze inikeze amazinga ahlukahlukene wesikhathi.
I-USART yesivinini esikhulu esithuthukisiwe
Inemisebenzi yekhodi yokuhlola ukukhiqizwa kwezingxenyekazi zekhompyutha, ukutholwa nokuqinisekiswa kwehadiwe, isigcinalwazi sokuthola amazinga amabili, ukulungisa okuzenzakalelayo nokubeka izinga le-baud, uhlaka lwedatha oluvikelayo, njll., okuthuthukisa ukwethembeka kokuxhumana, kusiza ukubhala uhlelo, futhi kulwenze kulula ukwakha inethiwekhi esabalalisiwe nokuqaphela Ukuze kusetshenziswe inkimbinkimbi yesistimu yokuxhumana yamakhompyutha amaningi, umsebenzi wembobo we-serial wedlula kakhulu i-serial port ye-MCS-51 single-chip microcomputer, futhi ngenxa yokuthi i-AVR single-chip microcomputer iyashesha futhi iyaphazamisa. isikhathi sesevisi sifushane, ingakwazi ukubona izinga eliphezulu lokuxhumana kwe-baud.
Ukuthembeka Kwesistimu Okuzinzile
I-AVR MCU inomjikelezo wokusetha kabusha amandla othomathikhi, isekethe ye-watchdog ezimele, i-BOD yokutholwa kwamandla kagesi aphansi, imithombo eminingi yokusetha kabusha (ukusetha kabusha amandla okuzenzakalelayo, ukusetha kabusha kwangaphandle, ukusetha kabusha kwe-watchdog, ukusetha kabusha kwe-BOD), ukubambezeleka kokuqalisa okulungisekayo Qalisa uhlelo noma kunini, okuthuthukisa ukwethembeka kwesistimu eshumekiwe.
2. Isingeniso sochungechunge lwe-AVR microcontroller
Uchungechunge lwamakhompiyutha e-AVR e-single-chip luqediwe, olungasetshenziswa ezidingweni zezikhathi ezahlukahlukene.Kunamabanga ama-3 esewonke, okuyilawa:
I-Low-grade Tiny series: ikakhulukazi i-Tiny11/12/13/15/26/28 njll.;
Uchungechunge oluphakathi kwe-AT90S: ikakhulukazi i-AT90S1200/2313/8515/8535, njll.;(ukususwa noma ukuguqulwa kube iMega)
I-ATmega yezinga eliphezulu: ikakhulukazi i-ATmega8/16/32/64/128 (umthamo wokugcina ngu-8/16/32/64/128KB) kanye ne-ATmega8515/8535, njll.
Izikhonkwane zedivayisi ye-AVR zisukela kwezingu-8 kuye kwezingu-64, futhi kukhona amaphakheji ahlukahlukene abasebenzisi abangawakhetha ngokuya ngezimo zangempela.
3. Izinzuzo ze-AVR MCU
Isakhiwo seHarvard, esinekhono lokucubungula isivinini esikhulu esingu-1MIPS/MHz;
Isethi yokufundisa encishisiwe esebenza kahle kakhulu (i-RISC), enamarejista okusebenza enhloso ejwayelekile angama-32, inqoba ukwenzeka kwebhodlela okubangelwa ukucubungula okukodwa kwe-ACC kwe-8051 MCU;
Ukufinyelela okusheshayo kumaqembu okubhalisa kanye nohlelo lwemiyalo yomjikelezo owodwa kuthuthukisa kakhulu usayizi nokusebenza kahle kwekhodi eqondiwe.Amanye amamodeli ane-FLASH enkulu kakhulu, elungele ikakhulukazi ukuthuthukiswa kusetshenziswa izilimi ezisezingeni eliphezulu;
Uma isetshenziswa njengokuphumayo, iyafana ne-HI/LOW ye-PIC, futhi ingakhipha u-40mA.Uma isetshenziswa njengokufakwayo, ingasethwa njenge-tri-state high-impedance input noma okokufaka nge-pull-up resistor, futhi inamandla okucwilisa okwamanje kusukela ku-10mA kuya ku-20mA;
I-chip ihlanganisa ama-oscillator e-RC nama-frequencies amaningi, amandla okusetha kabusha okuzenzakalelayo, i-watchdog, ukubambezeleka kokuqala kanye neminye imisebenzi, isifunda se-peripheral silula, futhi uhlelo luzinzile futhi luthembekile;
Ama-AVR amaningi anezinsiza ezicebile ze-chip: nge-E2PROM, PWM, RTC, SPI, UART, TWI, ISP, AD, Analog Comparator, WDT, njll.;
Ngokungeziwe kumsebenzi we-ISP, ama-AVR amaningi nawo anomsebenzi we-IAP, olungele ukuthuthukiswa noma ukucekela phansi izinhlelo zokusebenza.
4. Ukusetshenziswa kwe-AVR MCU
Ngokusekelwe ekusebenzeni okuhle kakhulu kwe-AVR ye-single-chip microcomputer kanye nezici ezingenhla, kungabonakala ukuthi i-AVR ye-single-chip microcomputer ingasetshenziswa kuzimo eziningi zohlelo lokusebenza ezishumekiwe okwamanje.
Ibhodi le-ATMEL MCU iyithuluzi lokuthuthukisa elithembeke kakhulu neliguquguqukayo elenzelwe amasistimu ashumekiwe.Inikeza izinhlobonhlobo zezici nemisebenzi yezinhlelo zokusebenza ezihlukahlukene kusukela ku-electronics yabathengi kuya ezishintshayo zezimboni.Enhliziyweni yaleli bhodi le-MCU kukhona i-ATMEL microcontroller eyaziwa ngokusebenza kwayo okuphezulu kanye nokusetshenziswa kwamandla okuphansi.Ngokusekelwe ekwakhiweni kwe-AVR, isilawuli esincane sihlinzeka ngokusebenza kwekhodi okusebenzayo nokuqinile kanye nokuhlanganiswa okungenamthungo nama-peripherals namadivayisi angaphandle.Ibhodi ifakwe izinhlobonhlobo zamapheripheral angaphakathi, okuhlanganisa izikhonkwane ze-GPIO, i-UART, i-SPI, i-I2C, ne-ADC, evumela ukuxhumana okungenamthungo nokuxhumana nezinzwa zangaphandle, ama-actuator, namanye amadivaysi.Ukutholakala kwalawa ma-peripheral kunikeza onjiniyela ukuguquguquka okukhulu ezinhlelweni zokwakha.Ngaphezu kwalokho, ibhodi le-ATMEL MCU linenkumbulo enkulu ye-flash ne-RAM, enikeza isikhala esanele sokugcina ikhodi nedatha.Lokhu kuqinisekisa ukuthi izinhlelo zokusebenza eziyinkimbinkimbi ezinezidingo ezinkulu zememori zingamukelwa kalula.Isici esiphawulekayo sebhodi i-ecosystem yayo ebanzi yamathuluzi okuthuthukisa isofthiwe.I-ATMEL Studio IDE inikeza inkundla esebenziseka kalula futhi enembile yokubhala, ukuhlanganisa nokulungisa amakhodi.I-IDE iphinde ihlinzeke ngomtapo wolwazi obanzi wezingxenye zesoftware, abashayeli kanye ne-middleware ukwenza lula inqubo yokuthuthukisa futhi kusheshiswe isikhathi sokumaketha.Amabhodi e-ATMEL MCU asekela izinqubo zokuxhumana ezahlukahlukene ezihlanganisa i-USB, i-Ethernet ne-CAN, azenze zifanelekele uhla olubanzi lwezinhlelo zokusebenza ezihlanganisa i-IoT, amarobhothi kanye ne-automation.Iphinde inikeze ngezinketho zokuphakelwa kwamandla okuhlukahlukene, okuvumela abathuthukisi ukuthi bakhethe ukunikezwa kwamandla ofaneleka kakhulu ngokusekelwe kuzidingo zabo zohlelo lokusebenza.Ukwengeza, ibhodi yakhelwe ukuthi ihambisane nohlu olubanzi lwamabhodi okunweba nama-peripherals, inikeze abathuthukisi amandla okusebenzisa amamojula akhona kanye nokwengeza ukusebenza njengoba kudingeka.Lokhu kuhambisana kuqinisekisa ukwenziwa kwe-prototyping okusheshayo nokuhlanganiswa okulula kwezici ezengeziwe.Ukusiza abathuthukisi, amabhodi e-ATMEL MCU eza nemibhalo ephelele ehlanganisa imininingwane yolwazi, izincwadi zabasebenzisi namanothi ohlelo.Ukwengeza, umphakathi ophilayo wabathuthukisi nabashisekayo uhlinzeka ngezinsiza ezibalulekile, ukwesekwa, namathuba okwabelana ngolwazi.Kafushane, ibhodi ye-ATMEL MCU iyithuluzi elinokwethenjelwa nelisebenza ngezindlela eziningi lokuthuthukisa uhlelo olushumekiwe.Nge-microcontroller yayo enamandla, izinsiza zenkumbulo ezibanzi, okuzungezile okuhlukahlukene okungaphakathi kwebhodi, kanye ne-ecosystem yentuthuko eqinile, ibhodi lihlinzeka ngendawo ekahle yokudala nokuhlola izinhlelo zokusebenza emikhakheni eyahlukene, iletha ubuhlakani benqubo yokuthuthukiswa nokusebenza kahle.
