Kauj Ruam 6: Txoj Cai V2 (software Debounce Nrog Timers)

Tom qab ib pliag ntawm kev ua si Kuv pom qee qhov teeb meem ob npaug nrog kev kho vajtse debounce. Qhov no tuaj yeem kho nrog qee lwm tus nqi tiv thaiv lossis cov khoom siv, tab sis raws li cov nyees khawm thiab lub hau tsis tuaj yeem tshem tawm Kuv xav tias software debouncing yuav yog ib qho kev daws teeb meem zoo. Kev tshaj tawm software yuav tsum ua haujlwm dua li kev kho vajtse debounce tau ua tiav lossis tsis yog. Hauv kuv qhov teeb tsa tam sim no kuv cound tsis tshem lub hau yog li kuv tsuas yog tso cov resistors thiab cov capacitors tso rau hauv qhov chaw.

Kuv yuav tsis piav qhia cov cai kom dav li yav dhau los vim tias nws nyuaj me ntsis los piav.

Yeej feem ntau ntawm cov cai ua haujlwm zoo ib yam thiab cov cai coj ua yog tsis muaj kev cuam tshuam. dab tsi hloov pauv yog kev cuam tshuam sab nraud tsis siv cov haujlwm arduino ntxiv lawm. Tam sim no nws ua haujlwm hauv C dawb huv. Thiab tam sim no dab tsi ntxiv yog software cuam tshuam. Txog qhov no kuv tau siv AVR lub sijhawm tos kom tau qee lub sijhawm kom txog rau thaum lub pob tau nres lawm. Vim tias cov timers cuam tshuam raws li lub sijhawm txiav txim siab tsis cuam tshuam los ntawm txhua yam tshwm sim hauv lub voj.

Tsuas yog qhov poob qis kuv tuaj yeem tuaj nrog yog qhov ua haujlwm qeeb ntawm arduino tsis tuaj yeem siv ntxiv lawm. Vim tias kev ua haujlwm qeeb siv Timer 0 thiab txoj haujlwm no siv Timer 0 los sib cav.

Hauv daim duab koj tuaj yeem pom tias txoj cai ua haujlwm li cas. Mem me ntsis qhia yog lub sijhawm ua haujlwm. Dab tsi tsis tau piav qhia yog rooj plaub uas thaum kawg ntawm lub pob nyem nias lub tswv yim qis. Hauv qhov no tsuas yog nias lub pob kom xa thaum lub pob twb tau tso tawm lawm. Qhov ntawd txhais tau tias tus yuam sij yuav raug tuav kom deb li deb tau ntawm lub computer. Txog qhov kev zam tsis tshua muaj no yuav muaj daim tshev ua ntej thaum lub sijhawm tas sijhawm. Yog tias qhov kawg ntawm lub sijhawm siv lub khawm tsis raug nias, yuav tsum xa cov lus txib tseem ceeb.

Kauj Ruam 7: Txoj Cai V3 (software Debounce With Vertical Counter) (pom zoo) (tsis muaj LED)

Txoj cai no tseem muaj qhov hloov pauv uas koj tsis xav tau rub cov neeg tawm tsam. Nco ntsoov tias koj txuas txhua lub pob rau lub tswv yim thiab GROUND! Kev tsim tawm hauv kev rub tawm yog siv

Kuv kuj tau ntsib qee qhov tsis tau sau npe hauv qhov chaws V2. Kuv xav tias txoj cai nyuam qhuav dhau los ua qhov nyuaj nrog nws lub sijhawm- thiab cuam tshuam sab nraud thiab kuv yuav tsis nco qee qhov tshwj xeeb. Vim li no kuv tau hais los ntawm kos nrog tshawb hauv is taws nem rau software debounce txoj kev.

(ua siab ncaj, tsawg kawg ib nrab ntawm txoj haujlwm no tau dhau los ua pob debouncing ntawm qhov no)

Tom qab qee qhov kev tshawb nrhiav kuv tau hla cov ntawv no:

www.compuphase.com/electronics/debouncing….

Yuav kom ncaj ncees, nws coj kuv qee lub sijhawm kom nkag siab zoo tias nws ua haujlwm zoo li cas. Nws cuam tshuam nrog qee qhov nyuaj me ntsis kev tswj hwm, tab sis kuv yuav sim ua kom yooj yim li sai tau. Txawm li cas los xij kuv cov lus piav qhia tsuas yog ntxiv rau hauv kab ntawv yog li koj yuav tsum tsawg kawg yog nyeem "cov ntawv ntsug", "kev piav qhia qhov ua tiav" thiab "txo qis qis".

Kuv piav qhia

Daim duab qhia sijhawm (ua hauv WaveDrom) Kuv ntxiv yuav tsum ua qhov nyuaj rau nkag siab lej lej tsawg kawg kom nkag siab me ntsis. Nco tseg daim duab muaj 2 qhov khoom me me, tab sis kuv tus lej muaj 3. Qhov no txhais tau tias yog lub sijhawm debounce ntev dua.
