Puas tau xav txog tias koj cov keyboard siv cov tswv yim li cas thiab cov ntaub ntawv khaws cia li cas! Qhov haujlwm no yog qhov me me ntawm cov ntaub ntawv nkag thiab khaws cia. Kev piav qhia ntxaws txog yuav ua li cas lub teeb liab los ntawm cov yuam sij, moos cuam tshuam lub cim xeeb (flip flops).
Kauj Ruam 1: Thaiv Daim Duab
1. Ntaus Ntaus
Asa binary 4 ntsis cov cuab yeej tawm tswv yim, tsuas muaj 2 lub laub khawm (ib qho rau npe 1 (siab) thiab lwm qhov rau 0 (qis) nrog lub suab nrov yuav tsum tsim kom muaj lub teeb liab nkag. yog nias lub teeb liab ib txwm hloov pauv mus rau qis).
2. Monostable Pulse Generator
Tom qab ntawv cov lus qhia nkag mus rau hauv lub tshuab hluav taws xob monostable tsim kom muaj cov mem tes uas muaj lub sijhawm ua haujlwm siab, nws tau ua los ntawm cov khoom siv me me mem tes.
3. Bi-ruaj khov Pulse Generator
Qhov mem tes no tseem tau tsav los ntawm cov kab teeb liab nkag mus, thaum tus lej (siab) raug nias lub teeb liab no tau teeb tsa thiab rov pib dua thaum tus yuam sij qis raug nias. Lub teeb liab tau pub raws li cov lus tso tawm sab laug rau qhov hloov pauv Sau npe.
4. Saib Sau Npe
4 qhov hloov pauv rau npe siv 4 flip-flops khaws cov ntaub ntawv. Nws yuav siv cov ntawv txuas nrog lub moos khaws cov ntaub ntawv los ntawm sab laug mus rau sab xis lossis sab xis mus rau sab laug. Hauv qhov haujlwm no cov ntaub ntawv xov xwm uas peb siv yog los ntawm Bi-stable pulse generator, thiab lub moos teeb liab los ntawm Monostable pulse generator.
5. Cov zis
LEDs qhia qhov tso tawm.
Kauj ruam 2: Sijhawm Daim Duab
Ib qho piv txwv Sijhawm Diagram uas yuav siv tus lej 0101. Lub tswv yim mem tes los ntawm khawm 1 thiab khawm 2 muaj qhov me me "sijhawm tsawg", qhov ntawd yog qhov laj thawj yog vim li cas nws thiaj pom zoo li qhov pom ntawm daim duab qhia sijhawm.
Kauj Ruam 3: Daim duab Circuit Court
Lub Sijhawm Siab rau mem tes monostable tuaj yeem hloov pauv los ntawm kev hloov RC tus nqi (kev tiv thaiv thiab tus nqi peev txheej). High sijhawm tau muab los ntawm t = 1.1*RC. Qhov siab lub sijhawm muaj qhov txwv qis dua uas nyob ntawm qhov kev hloov pauv tsis siv, txwv yog feem ntau 10-20ms. The lub sij hawm siab nyob rau hauv no Circuit Court tsim yog 1s (10k omh*100uf).
Qhov no los ntawm kev txo lub sijhawm no qhov nrawm ntawm lub cuab yeej tau nce.
Kauj Ruam 4: Fritzing Tsim Nrog BOM Cov Ntaub Ntawv
Rub tawm cov ntawv fritzing los kho qhov tsim thiab tsim koj tus kheej tsim.
Daim ntawv teev cov khoom siv xav tau muaj nyob hauv BOM cov ntaub ntawv.

PS4 Controller thiab Game Storage: 5 Kauj Ruam
PS4 Controller thiab Game Storage: Kuv tau tawm tsam nrog khaws kuv PS4 cov khoom siv rau lub sijhawm ntev tiag tiag. Kuv nyob hauv chav me me, thiab cov chaw uas kuv muaj feem ntau tau txais los ntawm ntau yam khoom, feem ntau yog txhua yam ntawm kuv lub thawv ntawv thiab cov tswj. Hauv ib ntawm kuv cov chav kawm hauv tsev kawm ntawv
