Параллельное подключение:

Pin 1 : VSS is the ground power supply

Pin 2 : VDD Positive power supply connected to 5V

Pin 3 : V0 LCD contrast adjustment for the end , connected to the positive power supply weakest contrast , when the power is grounded highest contrast

Pin 4 : RS for register selection , the selection of high data registers, low selection instruction register.

Pin 5 : R / W When the R / W and E are high , data is read DB0 ~ DB7; when R / W is low , E from high to low , DB0 ~ DB7 the data is written to IR or DR register .

Pin 6 : E enable signal

pin 7 to 14 : DB0 ~ DB7 is eight bidirectional data line.

pin 15 : PSB parallel / serial option. When the PSB is high in parallel mode ; when PSB is low, the serial mode. If your LCD screen 15 feet CS1, that is, non-character LCD screen KS0108 controller , restaurant for sale can contact the customer service staff

pin 16 : NC NC . If your LCD screen 16 feet CS2, that is, non-character LCD screen KS0108 controller , restaurant for sale can contact the customer service staff

pin 17 :/ RESET reset pin . Active low suburbs.

pin 18 : VOUT LCD driving voltage output , do not pick .

pin 19 : A backlight power supply positive, then 5 V.

pin 20 : K backlight negative power, ground.
