I. Gusobanura "Ikarita ya elegitoroniki"
"Ikarita ya elegitoroniki" ntabwo ari igikoresho cyo kubika umubiri ahubwo ni nini - igipimo e - umusomyi cyangwa terefone yo gusoma. Intego yacyo yibanze nukwigana imicungire yibitabo hamwe nuburambe bwo gusoma bwibitabo gakondo cyangwa ububiko bwibitabo muburyo bwa digitale.
II. Ibyingenzi byingenzi nibikorwa bya elegitoroniki yibitabo
1. Ibikoresho byibyuma ninshingano zabo
Kinini E Ink Kugaragaza: Uhereye kuri santimetero 7,8 kugeza kuri santimetero 13.3 cyangwa nini (nini cyane kuruta 6-7 cm e - abasomyi), itanga ahantu ho gusoma hasa nibitabo cyangwa ibinyamakuru. Benshi bakoresha tekinoroji ya E Ink muburyo bwo guhumuriza amaso no gukoresha ingufu.
Ibikorwa nyamukuru: Bishingiye kuri ARM Cortex - A cyangwa Cortex - M ikurikirana rya porogaramu (AP) cyangwa microcontrollers (MCU), ikora ibikorwa bya sisitemu, gutanga, gucunga dosiye, no gutumanaho imiyoboro.
Kwibuka: Harimo RAM (kubikorwa nyabyo - igihe) na Flash / ROM (kubikwa).
Umuyoboro udafite insinga: Wi - Fi ni bisanzwe; hejuru - moderi yanyuma irashobora kongeramo 4G / 5G cyangwa Bluetooth.
Batteri: Kinini - ubushobozi bwo gushyigikira amasomo yagutse yo gusoma.
Uburyo bwinjiza: Inkunga ya Touchscreen, hamwe na moderi zimwe zigumana page yumubiri - guhinduranya buto.
Isohora: USB - C (yo kwishyuza no kohereza amakuru), kandi birashoboka ko ikarita ya MicroSD.
Ibiranga amajwi: Abavuga na mikoro (kuri moderi zatoranijwe) zo gukinisha amajwi cyangwa kwinjiza amajwi.
2. Porogaramu & Ibikorwa Byibanze
E {0}
Gucunga Isomero: Gutegura ibyegeranyo binini nk'isomero ry'umubiri, rifasha gushyira mu byiciro, gushakisha, gutondeka, no gushyira akamenyetso.
Kwinjira Ibirimo: Ihuza binyuze kuri Wi - Fi kububiko bwibitabo byo kumurongo (byubatswe - cyangwa mugice cya gatatu -, nka JD Soma, WeChat Soma, Kindle) kugirango ukuremo kandi uhuze iterambere ryo gusoma.
Icyitonderwa & Ibisobanuro: Emerera inyandiko - gufata, kumurika, no gutangaza ukoresheje stylus cyangwa clavier.
Gukoresha Inyandiko: Yibanze ku gusoma PDF, ibisobanuro, no kwerekana; bimwe bifasha Office kureba inyandiko (nibyiza kumurimo / kwiga).
Kwagura porogaramu: Fungura sisitemu (urugero, Android) reka abakoresha bashireho - isoma rya gatatu cyangwa porogaramu zingirakamaro.
III. Crystal Oscillators mubitabo bya elegitoroniki: Amapaki, Inshuro, nibisobanuro
Ububiko bwibitabo bya elegitoronike, nkibintu byinjizwamo sisitemu, bisaba amasoko atandukanye kumasomo atandukanye. Hasi ni ugusenyuka kwa kristu ya oscillator isanzwe:

IV. Impamvu aba Oscillator ya Crystal ari ngombwa
Gutanga Igihe Cyuzuye "Umutima"
Ibice bya digitale nkibitunganya, module yitumanaho, hamwe ninteruro bishingiye kubimenyetso byamasaha bihamye kugirango bihuze ibikorwa. Bitabaye ibyo, sisitemu yakora nabi cyangwa igakora nabi.
Module y'Inama - Ibikenewe byihariye
Imikorere ya Processor: Hejuru - inshuro nyinshi, isaha nyamukuru ihamye (binyuze muri kugwiza PLL) itanga imikorere ya CPU neza.
Ubwiza bwa Wireless: Hejuru - ubunyangamugayo, hasi - icyiciro - kristu y’urusaku (urugero, 26 / 40MHz) ni ingenzi cyane kuri trans {transvers ya Wi - Fi / BT, bigira ingaruka ku buryo butaziguye guhuza imiyoboro, igipimo cyamakuru, hamwe n’ubuziranenge bwibimenyetso.
Igihe gikwiye: 32.768kHz RTC kristal ikomeza igihe nyacyo hamwe na ultra - imbaraga nke, ndetse no mugihe cyo gusinzira.
Guhuza imikorere: Gukoraho icyitegererezo, kwerekana kugarura, no gukina amajwi buri kimwe gikeneye amasaha yihariye kugirango uhuze ibikorwa.
Gushyigikira Miniaturisation
Ubuso - kwishyiriraho (SMD) kristu (3225, 2520, 2016, 1612) ikwiranye na PCB yoroheje, yujuje imbogamizi za elegitoroniki zigezweho.
Kwemeza gushikama no kwizerwa
Crystal igomba kwihanganira ihinduka ryubushyuhe no kunyeganyega, hamwe numurongo ukomeye - ihindagurika ryubushyuhe hamwe nigihe kirekire - igihe kirekire.
Kugenzura Imikoreshereze Yingufu
Hasi - imbaraga za kirisiti ya RTC yongerera igihe cyo guhagarara, mugihe imicungire myiza yizindi kristu igabanya gukoresha ingufu muri rusange.
Kuringaniza Igiciro n'imikorere
Ababikora bahitamo kristu zujuje ubuhanga bwa tekinike ku giciro cyiza, urebye itandukaniro mubunini bwa paki, ubunyangamugayo, nibirango.
V. Umwanzuro
Ububiko bwibitabo bya elegitoronike busaba ibintu bitandukanye, hejuru - imikorere ya kristu oscillator. Gusobanukirwa igishushanyo mbonera cya sisitemu na buri module ibisabwa byihariye (paki, inshuro, ubushobozi bwo gutwara ibintu, ibipimo byerekana) ni urufunguzo. Kuva kubitunganya kugeza kuri modules idafite simusiga na RTCs, ibi bice byigihe bigira ingaruka zitaziguye imikorere yimikorere, ituze, hamwe nuburambe bwabakoresha - bigatuma biba ingenzi kubitabo byibitabo bya elegitoroniki.
