Raspberry Pi LED Screen: Kev Xaiv, Teeb & Kev Qhia Txog Kev Ua Haujlwm
Kev sib koom ua ke ntawm Raspberry Pi nrog lub vijtsam LED qhib ntau yam ntawm cov tswv yim thiab cov tswv yim zoo - los ntawm cov ntaub ntawv scrolling dashboards mus rau cov xwm txheej kev cai. Tab sis lo lus "LED screen" suav nrog ntau hom khoom sib txawv, txhua qhov sib txawv ntawm kev sib txuas, software yuav tsum tau ua, thiab muaj peev xwm. Paub tias hom twg haum rau koj qhov project ua ntej koj yuav txuag lub sijhawm thiab zam kev ntxhov siab ntawm cov khoom siv tsis sib xws. Phau ntawv qhia no npog cov kev xaiv tseem ceeb kom meej.
Ob lub ntsiab lus sib txawv ntawm "LED Screen" rau Raspberry Pi
Thaum tib neeg tshawb nrhiav qhov project coj lub vijtsam raspberry pi, lawv feem ntau txhais tau tias yog ib qho ntawm ob yam uas txawv heev hauv kev xyaum:
HUB75 LED matrix vaj huam sib luag- modular ncaj qha- saib LED vaj huam sib luag siv hauv kev lag luam kos npe, muaj nyob rau hauv cov hom xws li 64 × 32 lossis 64 × 64 pixels, tsav ncaj qha los ntawm Raspberry Pi's GPIO pins ntawm matrix HAT (Hardware Txuas rau saum - ib qho ntxiv- ntawm lub rooj tsavxwm uas txuas ncaj qha mus rau lub teeb liab rau ib lub teeb liab txias rau LED panels).
LED-backlit LCD saib lossis HDMI cov duab- cov ntxaij vab tshaus txheem uas txuas rau Raspberry Pi ntawm HDMI lossis DSI (Display Serial Interface - ib qho kev sib txuas rau cov vaj huam sib luag me me), uas qhia cov zis tawm los ntawm Pi's operating system lossis daim ntawv thov ib yam li lawv xav tau los ntawm ib lub computer.
Thawj qeb yog dab tsi cov neeg tsim khoom feem ntau txhais tau tias thaum lawv piav qhia txog raspberry pi coj qhov project. Qhov thib ob yog tsuas yog siv Pi raws li lub computer txuas nrog tus qauv saib. Cov seem ntawm phau ntawv qhia no tsom feem ntau ntawm HUB75 matrix vaj huam sib luag mus kom ze, uas yog qhov tshwj xeeb tshaj plaws thiab nthuav dav.
HUB75 LED Matrix Panels: Tus Tsim Qauv
HUB75 yog tus qauv siv dav dav rau LED matrix zaub vaj huam sib luag, siv 16-pin connector kom tau txais cov cim scan los ntawm tus maub los. Cov vaj huam sib luag no tau tsim nyob rau hauv cov qauv ntau thiab tsawg thiab muaj dav los ntawm cov khoom siv hluav taws xob ntawm cov nqi nkag tau, ua rau lawv qhov kev xaiv de facto rau coj cov duab raspberry pi tej yaam num hauv lub tuam txhab tsim thiab kev kawm hauv zej zog.
Ib lub vaj huam sib luag HUB75 muaj tus lej tas li ntawm RGB pixels - cov hom muaj xws li 64 × 32 (2,048 pixels) thiab 64 × 64 (4,096 pixels). Ntau lub vaj huam sib luag tuaj yeem sib txuas ua ke - cov ntaub ntawv tawm ntawm ib lub vaj huam sib luag txuas mus rau cov tswv yim ntawm - tom ntej uas tso cai rau cov rooj sib tham loj dua los ntawm cov qauv.
Lub Raspberry Pi tsav lub vaj huam sib luag los ntawm kev tsim lub sijhawm thiab cov ntaub ntawv cov cim xav tau los tswj txhua lub xeev LED. Vim tias cov teeb liab no yog lub sijhawm-sensitive, ib qho kev mob siab rau RGB matrix HAT feem ntau pom zoo los ntawm GPIO txuas ncaj qha, vim nws muab cov buffering xav tau rau kev ua haujlwm txhim khu kev qha, tshwj xeeb tshaj yog thaum tsav tsheb ntau lub vaj huam sib luag ib txhij.
