Hauv qhov haujlwm no kuv tau ua cascadable 8x16 rgb coj matrix thiab nws tus tswj. Microchip's 18F2550 tau siv rau nws qhov kev txhawb nqa USB. RGB leds tau tsav los ntawm 74hc595 hloov npe nrog cov tiv thaiv. Rau cov duab thiab cov ntaub ntawv teeb tsa; 24C512 sab nraud eeprom tau siv. Kev teeb tsa thiab cov ntaub ntawv cov duab yog tsim los ntawm cov neeg siv duab sib tham (gui) ntawm lub khoos phis tawj thiab hloov mus rau eeprom ntawm USB Kuv ua kuv rgb coj matrix modules 8x16 pixel loj. Thiab lawv tuaj yeem txuas nrog ua thaj chaw loj dua.

architecture Animation thiab teeb tsa cov ntaub ntawv yog tsim los ntawm lub computer los ntawm gui. tom qab ntawd nws tau muab tso rau tswj lub rooj tsavxwm ntawm usb. Chav tswj hwm micro (mcu) hloov cov ntaub ntawv no mus rau chav khaws khoom ntawm pawg thawj coj (eeprom). Thaum pawg thawj coj ua haujlwm, nws xub nyeem cov ntaub ntawv teeb tsa: lub sijhawm sib nrug ntawm cov thav duab ntawm cov yeeb yaj kiab, qhov ntev ntawm cov duab kom pom, ua haujlwm hom (ib leeg lossis cascaded) tom qab ntawd nws nyeem ib ntu ntawm cov ntaub ntawv ua yeeb yaj kiab thiab xa cov ntaub ntawv mus rau cov ntawv sau npe hloov tshiab cov xwm txheej ntawm leds Hom anode rgb leds tau siv. leds tau teeb tsa 8 kab, 16 kab. txhua qhov anodes txuas nrog ib leeg uake. Hloov cov npe sau tswj ib kab ib zaug. Los ntawm multiplexing; 8 kab tau hloov kho nrawm heev yog li cov duab txuas ntxiv yog tso tawm. rau 8 kab --------- ib qho 8bit hloov pauv npe yog siv rau kev sib txuam sib luag. rau 16 rgb leds kab 16*3 = 48 ------ rau rau 8bit hloov pauv npe tau siv. Ntawm tus kheej hom ib tus qauv ua haujlwm raws li tau piav qhia saum toj no. Ntawm cascade hom: Ib lub rooj tsav xwm tau dhau los ua tus tswv tswj hwm thiab xa cov teeb liab sib txuas mus rau lwm cov laug cam ntawm cov xov tooj sib txuas sib txuas (spi). tag nrho cov laug cam tso cov duab tso rau ntawm lawv lub cim xeeb. Thiab lub sijhawm tau teeb tsa raws li lub teeb liab sib txuas los ntawm tus thawj tswj hwm.
