Microchip Atmega328P: mea uma e te manaʻomia e iloa e uiga i lenei MCU

Microchip ATmega328P

O le isi Vaega eletise e tatau ona e iloa o le microcontroller, poʻo le MCU (MicroController Unit), ATmega328P. O se tasi o sili ona lauiloa chips e mafai ona e polokalama mo le tele o faʻaoga o soʻo se ituaiga, uma DIY galuega faʻatino, e oʻo lava i isi pisinisi galuega, ma isi

E mautinoa o lona igoa e te masani ai, ma o se tasi o microchips faʻaaogaina e papatusi Arduino ma isi laupapa atinae Tali tutusa O le mea moni, i se vaega tele, o lenei tatalaina masini komepiuta faʻavae na saofaga foi i lona lauiloa siitia.

Mai Atmel i Microchip

tagavai o le microchip

Atmel Corporation o se kamupani semiconductor faʻavaeina i le 1984. O le kamupani igoa faʻavaeina e George Perlegos o le faʻapuʻupuʻu mo Advanced Technology mo Memory ma Logic.

I le latou talafaʻasolopito atoa, na latou atiaʻe ai masini RF, WiMAX, ASICs, SoCs, EEPROM ma faʻamanatuga manatua, ma isi. Ae, aemaise lava, ua latou taulaʻi foʻi i microcontrollers. Faʻatasi ai ma i latou, na latou aofia ai ni mafuaʻaga o le Intel 8051, o faʻavae i luga o le AVR ma le AVR32 (o tusiata fale na fausia e Atmel lava ia) ma faʻavae foi i le ARM

Lau oloa Sa latou auauna atu uma mo faaeletonika tagata faatau, e pei o kamupani tau fesootaiga, faaeletonika alamanuia, masini faafomai, taavale, vaega aerospace, kata mautu, ma foi le militeli.

E uiga i Tekinolosi Microchip, o se isi tele Arizona-faʻavae semiconductor gaosi oloa. Faʻapitoa mo microcontrollers, manatua (EEPROM ma EPROM), RF, ma isi analog masini, faʻapea foi ma mea faigaluega polokalama mo polokalame ma atinaʻe. O ana microcontrollers tu iloga faʻapitoa, ma se aiga atiaeina e latou lava pei o PICs.

O le a le microcontroller poʻo le MCU?

Un microcontroller, µC, UC poʻo le MCU (Microcontroller Unit), poʻo le a lava le mea e te manaʻo ai e faʻaigoaina, o se polokalame e mafai ona faʻatinoina IC mafai ona faʻatinoina ni oka ua utaina i lona mafaufau. O le mea lea, o le microcontroller e toeititi lava o se komepiuta atoa i luga o se malamala. O loʻo iai uma vaega tuʻufaʻatasia, pei ole CPU, RAM, ROM faʻapea foʻi ma I / O peripherals (GPIO, timers poʻo counters, A / D liliu, SPI, I2C, USB, Ethernet, faʻatusatusaga, PWM, ma isi).

E mautinoa lava, faatinoga o nei komupiuta i luga o le malamala e le tutusa le maualuga ma PC o loʻo i ai nei. Ae ui i lea, latou te matua lelei ma e masani ona sili ona lalelei mo eseese galuega e le manaʻomia ai le maualuga o gaioiga, pei o le puleaina o pisinisi alamanuia, faʻatonutonuina nisi o galuega i taʻavale, atinaʻe laupapa, mea faigaluega a le aiga, ma isi.

O le a le ATmega328P?

Atmel ATmega328p

El ATmega328P O se microcontroller na faia e Atmel, e aofia ai le megaAVR series. O le taimi nei e ana ia Microchip. E tusa ai ma ona faʻataʻitaʻiga ma sili ona maoaʻe uiga faʻapitoa o:

  • 8-bit AVR tusiata fale
  • 32 KB emo
  • 1 KB EEPROM
  • 2 KB SRAM
  • 23 lautele mafuaʻaga I / Le laina
  • 32 lesitala faʻamoemoe lautele
  • 3 timers / counters ma faʻatusatusaga faiga
  • Faʻalavelave i Totonu / Fafo (24)
  • Polokalame polokalama UART
  • Faʻasologa serial
  • SPI
  • 8-auala 10-bit A / D liliu
  • 6 PWM alaata
  • O le polokalame e mafai ona vaʻai ma le oscillator i totonu
  • 5 polokalama selectable mana faʻaola auala
  • 1.8v i le 5.5v paoa sapalai.
  • E mauaina le 1 MIPS o faʻatinoga, o lona uiga, tasi miliona faʻatonuga faʻataunuʻuina i sekone uma.
  • 20 Mhz uati masani
  • Afifi, e mafai ona avea fufui poʻo PLCC. Ma 28 pine.

A o lona pinout ma pepa faʻamaumauga, mafai download i latou mai ii.

O le a le AVR?

Afai e te mafaufau o le a le AVR, o se 8-bit RISC-ituaiga ata na fausia e Ateml mo lana laina o microcontrollers. Na muamua faʻapogai e ni tamaiti aʻoga se lua mai le Norwegian Institute of Technology, ma mulimuli ane faʻamamaina ma atiaʻe e Atmel Norway. Ua faʻaaogaina nei e laina ATmega, ATxmega, ATtiny, ma AT90.

E i ai le tusiata fale ua taʻua o le AVR32, o le 32-bit RISC ma le lagolago mo le DSP ma le SIMD. Faʻaaogaina mo sili atu masini alualu i luma e manaʻomia sili atu gaioiga ma faʻatinoga.

I se faʻaopopoga, e mulimuli a Harvard polokalame, e i ai le 32 8-bit resitara, ma sa masani ona fuafuaina ma tuʻufaʻatasia C faʻataunuʻuina i le mafaufau i se auala sili ona lelei.
