Sunungura Simba reATMEL MCU Mabhodhi
Details
Yakaiswa yemhando yepamusoro Flash program memory
Yepamusoro-mhando Flash iri nyore kudzima nekunyora, inotsigira ISP neIAP, uye yakanakira kugadzirisa chigadzirwa, kusimudzira, kugadzira, uye kugadzirisa.Iyo yakavakirwa-mukati-refu yehupenyu EEPROM inogona kuchengetedza kiyi data kwenguva yakareba kudzivirira kurasikirwa kana magetsi akadzimwa.Iyo yakakura-yakakura RAM mune chip haigone kuzadzisa zvinodiwa zvenguva dzese, asi zvakare zvinobudirira kutsigira kushandiswa kwepamusoro-level mutauro kugadzira zvirongwa zvehurongwa, uye inogona kuwedzera RAM yekunze seMCS-51 single-chip microcomputer.
Mapini ese eI/O ane zvinogadziriswa zvekudhonza-up resistors
Nenzira iyi, inogona kuiswa yega seyokupinza / kubuda, inogona kusetwa (yekutanga) yakakwirira-impedance yekuisa, uye ine yakasimba drive kugona (simba redhiraivha madhiraivha anogona kusiiwa), zvichiita kuti I / O zviwanikwa zvechiteshi zvichinjike, zvine simba, uye inoshanda zvizere.use.
On-chip akawanda akazvimirira wachi dividers
Inogona kushandiswa URAT, I2C, SPI zvichiteerana.Pakati pavo, iyo 8/16-bit timer ine kusvika ku10-bit prescaler, uye frequency division coefficient inogona kusetwa nesoftware kuti ipe mazinga akasiyana enguva yenguva.
Yakakwidziridzwa yepamusoro-soro UART
Iyo ine mabasa ekugadzirwa kwehardware cheki kodhi, kucherechedzwa kwehardware nekusimbisa, maviri-level kugamuchira buffer, otomatiki kugadzirisa uye chinzvimbo chebaud rate, kudzivirira data data, nezvimwewo, izvo zvinovandudza kuvimbika kwekutaurirana, kufambisa kunyora chirongwa, uye kuiita. zviri nyore kuumba network yakagoverwa uye kuona Nekuda kwekushandiswa kwakaoma kweakawanda-kombuta yekutaurirana system, iyo serial port basa rinopfuura zvakanyanya serial port yeMCS-51 single-chip microcomputer, uye nekuti iyo AVR single-chip microcomputer inokurumidza uye inovhiringidza. nguva yebasa ipfupi, inogona kuona yakakwira baud rate kutaurirana.
Yakagadzikana System Kuvimbika
AVR MCU ine automatic power-on reset circuit, yakazvimirira watchdog circuit, low voltage yekuona circuit BOD, multiple reset sources (otomatiki simba-pakugadzirisa, kunze reset, watchdog reset, BOD reset), configurable kutanga kunonoka Mhanyai purogiramu chero nguva, iyo inowedzera kuvimbika kweiyo yakamisikidzwa system.
2. Nhanganyaya kune AVR microcontroller series
Iyo yakatevedzana yeAVR single-chip microcomputers yakakwana, iyo inogona kuiswa kune zvinodiwa zvezviitiko zvakasiyana.Kune 3 mamakisi pamwero, ayo ari:
Low-giredhi Tiny akatevedzana: kunyanya Tiny11/12/13/15/26/28 etc.;
Mid-range AT90S akatevedzana: kunyanya AT90S1200/2313/8515/8535, nezvimwewo;(kubviswa kana kushandurwa kuita Mega)
High-giredhi ATmega: kunyanya ATmega8/16/32/64/128 (simba rekuchengetedza 8/16/32/64/128KB) uye ATmega8515/8535, nezvimwewo.
AVR mudziyo mapini anotangira pa8 mapini kusvika pa64 mapini, uye kune akasiyana mapakeji evashandisi kusarudza zvinoenderana nemamiriro chaiwo.
3. Zvakanakira AVR MCU
Harvard chimiro, ine 1MIPS/MHz yakakwirira-kumhanya kugadzirisa kugona;
Super-functional yakaderedzwa instruction set (RISC), ine 32 general-chinangwa marejista ekushanda, inokunda iyo bottleneck phenomenon inokonzerwa neiyo imwechete ACC processing ye8051 MCU;
Kukurumidza kuwana kunyoresa mapoka uye imwechete-kutenderera yekuraira sisitimu inogonesa zvakanyanya saizi uye nekuita mashandiro eiyo kodhi kodhi.Mimwe mienzaniso ine FLASH yakakura kwazvo, iyo inonyanya kukodzera kusimudzira uchishandisa mitauro yepamusoro;
Kana ichishandiswa sechinhu chinobuda, chakafanana nePIC's HI/LOW, uye inogona kuburitsa 40mA.Kana ichishandiswa sechipo, inogona kuiswa seye tri-state yakakwirira-impedance yekupinda kana yekuisa ine yekudhonza-up resistor, uye inokwanisa kunyura ikozvino kubva ku10mA kusvika 20mA;
Iyo chip inobatanidza RC oscillators neakawanda mafrequencies, simba-pane otomatiki reset, watchdog, kutanga-up kunonoka uye mamwe mabasa, peripheral circuit iri nyore, uye sisitimu yakanyanya kugadzikana uye yakavimbika;
MaAVR mazhinji ane hupfumi pa-chip zviwanikwa: neE2PROM, PWM, RTC, SPI, UART, TWI, ISP, AD, Analog Comparator, WDT, nezvimwewo;
Pamusoro peiyo ISP basa, maAVR mazhinji zvakare ane IAP basa, iri nyore kusimudzira kana kuparadza maapplication.
4. Kushandiswa kweAVR MCU
Zvichienderana nekuita kwakanaka kweiyo AVR single-chip microcomputer uye hunhu huri pamusoro, zvinogona kuoneka kuti iyo AVR single-chip microcomputer inogona kuiswa kune yakawanda yakamisikidzwa maficha ekushandisa parizvino.
Iyo ATMEL MCU bhodhi chishandiso chakavimbika uye chinogoneka chekusimudzira chakagadzirirwa akamisikidzwa masisitimu.Inopa huwandu hwakawanda hwezvinhu uye mabasa kune akasiyana siyana ekushandisa kubva kumagetsi evatengi kusvika kumaindasitiri otomatiki.Pamwoyo weiyi MCU bhodhi pane ATMEL microcontroller inozivikanwa nekuita kwayo kwepamusoro uye kuderera kwesimba rekushandisa.Zvichienderana neiyo AVR dhizaini, iyo microcontroller inopa inoshanda uye yakasimba kodhi dhizaini uye isina musono kusanganisa nemaperipheral uye ekunze zvishandiso.Bhodhi racho rakashongedzerwa neakasiyana-siyana epaboard peripherals, anosanganisira GPIO mapini, UART, SPI, I2C, uye ADC, inogonesa kubatanidza isina musono uye kutaurirana nekunze sensors, actuators, uye zvimwe zvishandiso.Kuvepo kweaya maperipheral kunopa vanogadzira kuchinjika kukuru mukuvaka maapplication.Uye zvakare, iyo ATMEL MCU bhodhi ine yakakura flash memory uye RAM, ichipa yakakwana nzvimbo yekuchengetedza kodhi uye data.Izvi zvinovimbisa kuti zvikumbiro zvakaomarara zvine hombe ndangariro zvinodiwa zvinogona kugadziriswa nyore.Chinhu chakakosha chebhodhi ndeye yakakura ecosystem yematurusi ekuvandudza maturusi.ATMEL Studio IDE inopa mushandisi-ane hushamwari uye intuitive chikuva chekunyora, kuunganidza uye kugadzirisa kodhi.Iyo IDE inopawo raibhurari yakakura yezvikamu zvesoftware, vatyairi uye middleware kurerutsa maitiro ekusimudzira uye nekumhanyisa nguva yekutengesa.ATMEL MCU mabhodhi anotsigira akasiyana maprotocol ekutaurirana anosanganisira USB, Ethernet neCAN, achiita kuti ave akakodzera kune zvakasiyana siyana zvekushandisa zvinosanganisira IoT, marobhoti uye otomatiki.Inopawo zvakasiyana-siyana zvemagetsi emagetsi sarudzo, zvichibvumira vanogadzira kuti vasarudze yakanyanya kukodzera magetsi zvichienderana nezvinodiwa zvekushandisa.Pamusoro pezvo, bhodhi rakagadzirwa kuti rienderane neakasiyana siyana ekuwedzera mabhodhi uye peripherals, ichipa vanogadzira kuchinjika kwekusimudzira mamodule aripo uye kuwedzera mashandiro sezvinodiwa.Uku kuenderana kunovimbisa kukurumidza prototyping uye nyore kubatanidzwa kwemamwe maficha.Kubatsira vanogadzira, mabhodhi eATMEL MCU anouya nemagwaro akakwana anosanganisira madheti, zvinyorwa zvevashandisi uye zvinyorwa zvekushandisa.Pamusoro pezvo, nharaunda ine simba yevagadziri uye vanofarira inopa zvakakosha zviwanikwa, rutsigiro, uye ruzivo-kugovana mikana.Muchidimbu, iyo ATMEL MCU bhodhi ndeye yakavimbika uye inoshanda zvakasiyana-siyana yakadzamirirwa system yekuvandudza chishandiso.Iine ine simba microcontroller, yakakura ndangariro zviwanikwa, akasiyana onboard peripherals, uye yakasimba yekusimudzira ecosystem, iyo bhodhi inopa yakanakira chikuva chekugadzira uye kuyedza maapplication munzvimbo dzakasiyana siyana, kuunza hunyanzvi mukuvandudza maitiro uye kushanda nesimba.
