CSX ke khetho ea chip ea makhoba, 'me chip e tla lumelloa feela ha CSX e le maemong a tlase a matla. D/CX ke phini ea taolo ea data/taelo ea chip. Ha DCX e ngola litaelo maemong a tlase, data e ngotsoe maemong a phahameng SCL ke oache ea libese ea SPI, e nang le moeli o mong le o mong o ntseng o phahama o fetisang 1 bit ea data; SDA ke data e fetisoang ke SPI, e fetisang likotoana tse 8 tsa data hang. Sebopeho sa data se bontšoa setšoantšong se latelang:
Phahamisa hanyane pele, fetisetsa pele. Bakeng sa puisano ea SPI, data e na le nako ea phetisetso, e kopantseng karolo ea nako ea sebele ea oache (CPHA) le polarity ea nako (CPOL): Boemo ba CPOL bo lekanya boemo ba boemo bo sa sebetseng ba nako ea serial synchronous, le CPOL=0, e bontšang boemo bo tlase. CPOL pair transmission protocol Puisano e ne e se na tšusumetso e ngata; Bophahamo ba CPHA bo etsa qeto ea hore na oache ea serial synchronous e bokella lintlha ka lehlakoreng la pele kapa la bobeli la ho tlola, Ha CPHL=0, etsa pokello ea data pheletsong ea pele ea phetoho; Motsoako oa mefuta ena e 'meli ea mekhoa e mene ea puisano ea SPI, le SPI0 e sebelisoa hangata Chaena, moo CPHL=0 le CPOL=0
Tlhaloso ea Hardware
6P capacitive touch screen interface FPC
P1 ke sets'oants'o sa FPC se nang le sebaka sa 6P 0.5mm, se sebelisetsoang ho hokahanya thapo ea 6P FPC ea capacitive touch screen le ho hokahanya matšoao.
Phepelo ea motlakase voltage tsitsisa potoloho
Potoloho ena e sebelisetsoa ho tsitsisa phallo ea voltage ea mojule, moo VCC e leng voltage, VCC3.3V ke mojule oa ho kenya voltage, 'me C1 ke "bypass filter capacitor". VCC e ka kopanngoa le 5V kapa 3.3V, 'me e kgothaletswa ho hokela 5V hobane feela ka ho hokela 5V ho ka VCC3.3 tlhahiso 3.3V. Haeba e hokahane le 3.3V, VCC3.3 output voltage tla ba ka tlase ho 3.3V, e leng se tla etsa hore khanya ea backlight ea skrine ea LCD e fifale.
Pokello ea sekotjana sa karete ea SD
SD_ CARD1 ke sekotjana sa karete ea Micro SD bakeng sa ho kenya likarete tsa Micro SD, ho nolofalletsa ho sebelisa mesebetsi ea katoloso ea karete ea SD. Bese ea SPI le LCD tse sebelisitsoeng lia arolelanoa.
Backlight control circuit
R1 e boloketsoe ho lumellana le potoloho ea taolo ea J3Y, ka ho toba e sebelisa 0 ohm resistor.
