Kukho iintlobo ezininzi ze-LCD interfaces, kwaye ulwahlulo lulungile kakhulu.Ikakhulu ixhomekeke kwindlela yokuqhuba kunye nemo yolawulo yeLCD.Okwangoku, kukho iintlobo ezininzi zokudityaniswa kombala weLCD kwifowuni ephathwayo: imowudi ye-MCU, imo ye-RGB, imo ye-SPI, imo ye-VSYNC, imo ye-MDDI, kunye nemo ye-DSI.Imowudi ye-MCU (ikwabhalwa kwimo ye-MPU).Kuphela yimodyuli ye-TFT ene-interface ye-RGB.Nangona kunjalo, isicelo singaphezulu kwemodi ye-MUC kunye nemowudi ye-RGB, umahluko umi ngolu hlobo lulandelayo:
1. I-interface ye-MCU: Umyalelo uya kugqitywa, kwaye ijeneretha yexesha liya kuvelisa iimpawu zexesha lokuqhuba i-COM kunye ne-SEG abaqhubi.
Ujongano lweRGB: Xa ubhala useto lwerejista yeLCD, akukho mahluko phakathi kojongano lweMCU kunye nojongano lweMCU.Umahluko kuphela yindlela obhalwe ngayo umfanekiso.
2. Kwimo ye-MCU, ekubeni idatha ingagcinwa kwi-GRAM yangaphakathi ye-IC kwaye emva koko ibhalwe kwisikrini, le modi ye-LCD inokudibaniswa ngokuthe ngqo kwi-MEMORY ibhasi.
Yahlukile xa usebenzisa imowudi yeRGB.Ayinayo i-RAM yangaphakathi.HSYNC, VSYNC, ENABLE, CS, RESET, RS inokudityaniswa ngokuthe ngqo kwi-GPIO port ye-MEMORY, kwaye i-GPIO port isetyenziselwa ukulinganisa i-waveform.
3. Imodi yojongano lwe-MCU: Idatha yokubonisa ibhalwe kwi-DDRAM, ehlala isetyenziselwa ukubonisa umfanekiso.
Imowudi yojongano lweRGB: idatha yokubonisa ayibhalwanga kwiDDRAM, isikrini sokubhala ngokuthe ngqo, ngokukhawuleza, sihlala sisetyenziselwa ukubonisa ividiyo okanye oopopayi.
Imowudi ye-MCU
Ngenxa yokuba isetyenziswa kakhulu kwintsimi yee-microcomputers ze-single-chip, ithiywe ngegama layo.Isetyenziswa kakhulu kwiifowuni eziphathwayo ezikumgangatho ophantsi kunye nophakathi, kwaye eyona nto iphambili kukuba ayibizi kakhulu.Isigama esiqhelekileyo se-interface ye-MCU-LCD yi-Intel's 8080 yebhasi eqhelekileyo, ngoko i-I80 isetyenziselwa ukubhekisela kwisikrini se-MCU-LCD kumaxwebhu amaninzi.Ikakhulu inokwahlulwa ibe yimo ye-8080 kunye ne-6800 imowudi, umahluko omkhulu phakathi kwezi zibini lixesha.I-bit data transmission ina-8 bits, 9 bits, 16 bits, bits 18, kunye ne-24 bits.Umdibaniso wahlulwe: CS/, RS (register selection), RD/, WR/, kwaye emva koko ulayini wedatha.Inzuzo kukuba ulawulo lulula kwaye lufanelekile, kwaye akukho clock kunye neempawu zokuvumelanisa ezifunekayo.Ukungalungi kukuba kubiza i-GRAM, ngoko kunzima ukufezekisa isikrini esikhulu (3.8 okanye ngaphezulu).Kwi-LCM ye-interface ye-MCU, i-chip yangaphakathi ibizwa ngokuba ngumqhubi we-LCD.Umsebenzi ophambili kukuguqula idatha / umyalelo othunyelwe ngumninimzi kwidatha ye-RGB yepikseli nganye kwaye uyibonise kwisikrini.Le nkqubo ayifuni inqaku, umgca, okanye iiwotshi zesakhelo.
Imo ye-SPI
Isetyenziswe ngaphantsi, kukho imigca emi-3 kunye nemigca emi-4, kwaye uxhulumaniso luyi-CS /, i-SLK, i-SDI, i-SDO imigca emine, uxhulumaniso luncinci kodwa ulawulo lwesofthiwe luyinkimbinkimbi.
Imo yeDSI
Le mowudi ye-serial bidirectional high-speed command transmission mode, uxhumano lune-D0P, D0N, D1P, D1N, CLKP, CLKN.
Imo ye-MDDI (MobileDisplayDigitalInterface)
I-Qualcomm's interface MDDI, eyaziswa ngo-2004, iphucula ukuthembeka kwefowuni yeselula kunye nokunciphisa ukusetyenziswa kwamandla ngokunciphisa i-wiring, eya kuthatha indawo yemodi ye-SPI kwaye ibe yi-serial interface ye-serial ye-serial ye-mobile.Uqhagamshelo luyidatha yehosti, host_strobe, client_data, client_strobe, power, GND.
Imowudi yeRGB
Isikrini esikhulu sisebenzisa iindlela ezininzi, kwaye i-data bit transmission ine-bits eyi-6, i-16 bits kunye ne-18 bits, kunye ne-24 bits.Uqhagamshelo lubandakanya ngokubanzi: VSYNC, HSYNC, DOTCLK, CS, RESET, kwaye ezinye zifuna i-RS, kwaye enye yilayini yedatha.Izibonelelo zayo kunye nokungalunganga zichasene ngqo nemodi ye-MCU.
