Uxwebhu okanye u-dashit: yintoni na, phi na ukufumana kunye nendlela yokuyisebenzisa

Kwintetho yabantu abasebenzisana nekhompyutheni, kukho ibinzana: "Sidinga ukujonga i datashit". Yintoni eyayisetyenziswe kwaye yintoni ekufumaneni i datasheet eyaziwayo?

Igama libolekekwe kwisiNgesi kwaye okokuqala kubhaliwe njenge datasheet. Ukuba uguqulela kwisiRashiya, ngokuqinisekileyo ufumane "ishidi ngolwazi." Olu xwebhu lenziwe ngamacebo ahlukeneyo kunye nezixhobo zombane. Ngako oko, kuchanekile ukutsho ukuba idatha ye-datasheet yimibhalo yobugcisa elungiselelwe ngumenzi.

Khangela izixhobo zombane

Mhlawumbi kuya kucaca ukuba i-datasheet ye-chip emva kokuba ivuliwe. Kodwa umbuzo: "Ndingayifumana phi na?"

KwiSoviet Union, amaxwebhu ayemisiwe. Ukuba kwakudingeka ukuba ufumane ulwazi malunga nomtshintshi okanye i-microchip, kwakufuneka ukuba uthathe ukhokelo olufanelekileyo. Namhlanje isidingo solawulo sele sinyamalale. Batshintshwa ngeenjini zokukhangela - ngokwaneleyo ukuqhuba igama elithi datasheet kwaye ucacise igama lefowuni oyifunayo. Inketho yesibini kukufumana i-datasheet-ukuya kwindawo apho amaxwebhu eqokelelwa khona, kwaye kukho ukuqhuba uphando.

Iinkcukacha zeenxalenye zinikezelwa njengeifayile ze-PDF. Ungawavula ngokukhawuleza kwisiphequluli.

Ikhasi lokuqala le datasheet

Emva kokuba uxwebhu lukhutshwe kwikhompyutheni, kufuneka uvule i datasheet. Yintoni equlethe, yintoni eyokujonga kuqala?

Kufuneka uqale ukusuka kwiphepha lokuqala. Inika ulwazi olugxininisa ukuchaneka kwesicaciso esithile, njengoluhlu olubanzi lwamanqanaba, ukusetyenziswa kwamandla amancinci, ukukhanya okumanzi okuphantsi.

Ikhasi lokuqala leenkcukacha zobugcisa liqulethe:

• Iipropati zendawo;
• Inkcazelo (inkcazelo / inkcazo jikelele) ;
• Qinisekisa ukucwangcisa

Kufuneka kuqatshelwe ukuba ulwazi olunikeziwe aluhlali lwaneleyo, ngoko akufanele ukulithemba ngokupheleleyo. Izimpendulo kwimiba evelayo kufuneka ifunwe kumacandelo afanelekileyo oxwebhu. Injongo yephepha lokuqala kukunika ingcamango yalo, oko kukuthi, ukuxelela oko.

I-datasheet ye-transistor encinci ifaniswa nombhalo ofanayo kunye ne-microcircuits, ngoko iphepha lokuqala libonisa ngokukhawuleza ulwazi malunga neerameters kunye nokuxhamla.

Umxholo wexwebhu

Ngokuqhelekileyo, abasebenzisi babuza malunga ne datasheet: "Yintoni na indlela yokuyifunda?" Ukuba ukukhishwa kokuqala kwaqwalaselwa, ngoko ke okwesibini akukafuneka ifundwe.

Iinjineli zee-elektroniki ziqwalasela ezi candelo zilandelayo zolu xwebhu.

• Ukucoca.

Uchaza injongo yepini nganye ye-microchip okanye i-transistor. Umyili ubeka izigqibo phantsi kweempawu zeVcc kunye ne-GND. Iyokuqala yazo yenzelwe ukubonelela ngexabiso lonikezelo (ngokuqhelekileyo +5 V), okwesibini - ukuxhuma "umhlaba". Abalawuli be-microcontrollers bangaba nezigqibo ezinjalo. Indawo yabo incike kwihlobo lezindlu (PDIP / TQFP / MLF).

• Umzobo weDivaysi (i-Block Diagram).

Ubonisa umxholo wangaphakathi kwecandelo. Umzekelo, i-microcontroller ibonisa imemori yayo, i-generator yewashi, ii-O / O.

• Isekethi yeSekethi.

Icacisa isixhobo soxhumano lwefowuni. Ngokwenza oko, amaqhinga ahluke kwalawo anikwe amaxwebhu, kuba kwimeko nganye ethile i-chip okanye i-transistor yinxalenye yesicatshulwa esiyinkimbinkimbi esicacisiweyo apho zonke izixhobo zayo kufuneka ziqwalaselwe.

• Ukushisa kunye neerameter parameters.

Ezi zithethe zinikezelwa ngefayile ezibonisa ukuxhomekeka kweramitha enye kwenye.

Iingcebiso zokugqibela

Umqhubi we-novice wezixhobo zeekhompyutheni akahlali eqonda indlela yokufunda i datasheet, yintoni isakhiwo socwangciso kunye nesizathu sokuba ipinki iyadingeka. Nangona kunjalo, kucetyiswa ukuba ufunde izixhobo zokufunda xa uhlahlela isitsha esitsha okanye ulungisa izixhobo zokusebenza.
