Tus tuav lub vijtsam LCD siv ntawm tus xov tooj sib txuas lus, tus qauv microprocessor thiab tus LCD kov tshuaj ntsuam lub npog tswj. Daim duab thaiv txheej txheem ntawm daim duab yog qhia hauv daim duab 1.

Kev sib txuas lus module feem ntau muaj xws li peripherals interface xws li lub npav caij nplooj ntoos hlav (USB) thiab Ethernet, uas tsim kev sib txuas lus ntawm microprocessors thiab lwm cov khoom siv.


Microprocessor module, raws li lub tsev tswj lub ntsiab lus tseem ceeb, feem ntau suav cov txheej txheem ntawm phab ntsa, tsav tsheb txheej thiab daim ntawv txheej txheem. Nws tuaj yeem tswj cov tswv yim thiab cov zis ntawm LCD kov npo. Cov txheej txheem Radion pom cov STM32F407 hom micro xws li, uas pom cov khoom kho vajtse hauv kev sib txuas ntawm cov kev tswj microprocessor.

Cov tsav tsheb muaj xws li FSMC npav tsav tsheb, USB tsav tsheb, Ethernet tsav tsheb thiab cov neeg tsav tsheb, yuav tsav tau lub tshuab hluav taws xob nrog cov kev sib txuas lus sab nraud thiab cov ntaub ntawv ntim ntawm cov ntaub ntawv siab. Cov txheej txheem daim ntawv thov tsuas yog hloov cov software software package emWin5.22, uas muaj peev xwm paub qhov tsim ntawm tib neeg-lub computer kev sib cuam tshuam thiab cov tswv yim thiab cov kev tawm tswv yim ntawm cov ntaub ntawv.


Lub koob ntim LCD touch screen module muaj xws li ib cov qauv nruab nrab ntawm cov qauv nruab nrab, lub tshuab cim xeeb, tus qauv module thiab tus tswj kev kov, tus neeg tsav tsheb thiab cov tsav tsheb tuaj yeem ua tau kov LCD. Ntawm lawv, cov ntaub ntawv txauv ntawm cov ntaub ntawv thiab cov ntaub ntawv teeb meem yog ua raws li FSMC lub npav, paub cov ntaub ntawv txauv ntawm ARM thiab FPGA; lub cim xeeb module yog siv los ua kua crystal display zaub cia; kua Crystal display module ua tiag pom txog kev tswj cov kua tshuaj tua kua hluav taws xob, ua kua dej ua kua teeb; kov tswj module yog siv los tsav ADS7843 LCD kov nti, LCD kov muaj nuj nqi.


LCD kov npo tswj qhov system workflow: microprocessor module los ntawm kev sib txuas lus module mus sau cov ntaub ntawv thiab xa cov ntaub ntawv mus rau cov ntaub ntawv txauv ntawm cov ntaub ntawv, cov ntaub ntawv txauv rau cov ntaub ntawv ua lag luam thiab sau cov cim xeeb hauv cov kua hluav taws xob ua qauv hauv qab ntawm kev tswj ntawm cov ntaub ntawv los ntawm lub cim xeeb module nyeem thiab ua kom tiav cov lus; nyob rau tib lub sij hawm, tus tswj cov cai tswj tus kov kov nti tsis tu ncua tas nrho tus nqi thiab hloov cov nqi ntawm tus nqi siab, lub microprocessor module timing mus rau lub LCD kov tshuaj ntsuam tswj module xa ib cov lus hais kom ua, ncaj qha nyeem cov hauj lwm ntawm qhov kov ua tiav.
