1602 siv tus qauv 16-pin interface, uas:
Pin 1: GND yog lub zog hauv av
Tus pin thib ob: VCC txuas nrog tus ncej zoo ntawm 5V fais fab mov
Tus pin thib peb: V0 yog qhov sib piv ntawm qhov hloov pauv ntawm LCD. Qhov sib piv yog qhov tsis muaj zog thaum lub zog zoo txuas nrog, thiab qhov sib txawv yog qhov siab tshaj plaws thaum lub zog yog hauv av (qhov sib piv yuav siab dhau thaum qhov sib txawv siab dhau lawm, thiab qhov sib txawv tuaj yeem hloov kho los ntawm 10K potentiometer).
Tus pin thib plaub: RS yog kev xaiv rau npe, thaum qib siab yog 1, cov ntaub ntawv sau npe raug xaiv, thiab thaum qib qis yog 0, cov ntawv qhia kev sau npe raug xaiv.
5 tus pin: RW yog qhov nyeem thiab sau cov kab teeb liab, nyeem cov haujlwm ntawm qib siab (1),
Daim duab schematic yooj yim nrog 51 ua piv txwv ua haujlwm sau ntawv ntawm qib qis (0).
6 tus pin: E (lossis EN) kawg yog pab (pab kom) kawg, nyeem cov ntaub ntawv thaum qib siab (1), tsis zoo dhia
Ua cov lus qhia thaum hloov.
Pins 7~14: D0~D7 yog 8-ntsis bidirectional data terminals. 15th ~ 16th ko taw: khoob ko taw lossis rov qab teeb
qhov chaw. 15 tus pin backlight yog qhov zoo, thiab 16 tus pin backlight yog qhov tsis zoo.
yam ntxwv

Kev tswj kev ua haujlwm
Nco tseg: Hais txog E{{0}}H pulse-- pib E rau 0 thaum pib, thiab tom qab ntawd teeb E rau 1.
