Yog li yog tias koj xav piv arduinos nrog AVRs (Uno, Nano, Leonardo) thiab Arduinos nrog ARMs (Due, Zero, Teensy), qhov loj txawv yog li ntawd AVR yog 8-ntsis architecture, thiab cov ARM yog 32-ntsis architecture.

Hauv qhov no, AVR thiab ARM yog dab tsi?

ARM yog microprocessor lossis CPU architecture thaum AVR yog microcontroller. ARM tuaj yeem siv zoo ib yam li microcontroller thaum ua ke nrog ROM, RAM thiab lwm yam khoom siv peripheralsto ib lub nti xws li LPC2148. Yog li cov lus nug yog dab tsi yog qhov txawv ntawm microcontroller thiab microprocessor.

Kuj Paub, vim li cas AVR microcontroller siv? AVR yog ib tug thawj microcontroller cov tsev neeg siv on-chip flash nco rau cov kev pab cuam cia, asopposed rau ib zaug programmable ROM, EPROM, los yog EEPROM siv los ntawm lwm yam microcontrollers thaum lub sijhawm. AVR microcontrollers nrhiav tau ntau daim ntawv thov raws li embedded systems.

Hais txog qhov no, puas yog Arduino AVR lossis ARM?

Arduino feem ntau yog koj li AVR ATMEGA 328 microcontroller. Vim li no, AVR yog 8 ntsis RISC tshuab uas muaj 8M (megabytes) ntawm qhov chaw thauj khoom rau hauv ROM thiab 64K RAM. ARM CORTEX yog Advanced RISC Tshuab, lwm qhov kev txhim kho sai hauv kev ua lag luam.

Koj txhais li cas los ntawm AVR?

1. luv rau tsis siv neeg voltage regulator, AVR isa hardware device siv los tswj qhov voltage rau cov khoom siv hluav taws xob.2. Luv luv rau lub suab tsis siv neeg paub, AVR yog lub peev xwm ntawm lub computer lossis lwm yam khoom siv hluav taws xob los txheeb xyuas thiab nkag siab tib neeg lub suab.
