TFT LCD LCD interface hom kev sib piv

Tam sim no, muaj ntau yam kev sib txuas lus tseem ceeb ntawm TFT LCD zaub: MCU interface, RGB interface, SPI interface, MIPI interface, QSPI interface, LVDS interface.

Muaj ntau daim ntawv thov yog MCU interface thiab RGB interface thiab SPI interface, feem ntau qhov sib txawv hauv qab no:

MCU interface: yuav txiav txim siab cov lus txib, lub tshuab hluav taws xob lub sijhawm los tsim cov cim lub sijhawm, tsav COM thiab SEG tsav.

RGB interface: Thaum sau LCD sau npe teeb tsa, tsis muaj qhov sib txawv nrog MCU interface. Qhov txawv tsuas yog nyob rau hauv yuav ua li cas daim duab sau.

SPI interface: SPI (Serial Peripheral Interfacce), serial peripheral interface, yog ib qho synchronous serial cov ntaub ntawv xa tawm tus qauv npaj los ntawm MOTOROLA.

SPI interface feem ntau hu ua 4-xaim serial tsheb npav, lossis nws tuaj yeem yog 3-xaim SPI interface, uas ua haujlwm hauv hom tswv / qhev, thiab cov txheej txheem hloov ntaub ntawv yog pib los ntawm tus tswv.

SPI CLK, SCLK: Serial moos, siv rau synchronous cov ntaub ntawv hloov tsheb, tso zis los ntawm tus tswv tsev

CS: Chip xaiv kab, nquag qis, tso tawm los ntawm tus tswv tsev

MOSI: master output, qhev input data line

MISO: Master input, qhev tso zis cov ntaub ntawv kab

Tsis muaj qhov hu ua qhov zoo tshaj plaws los yog phem tshaj ntawm kev sib cuam tshuam, tsuas yog tsim nyog thiab tsis siv rau cov khoom siv; Yog li ntawd, peb npaj cov ntaub ntawv los muab cov lus hauv qab no, rau ntau yam interfaces qhia hauv tsab xov xwm no, muab ntau qhov zoo thiab qhov tsis zoo tsom xam, yog li koj tuaj yeem txheeb xyuas thiab sib piv kom paub qhov tsim nyog tshaj plaws interface rau koj cov khoom. .
