Pin 1: VSS is the ground power supply.

Pin 2: VDD is connected to a 5V positive power supply. ,

The third pin: VL is the contrast adjustment terminal of the liquid crystal display. The contrast is weak when connected to a positive power supply,

and the contrast is high when grounded. When the contrast is too high, "ghosts" will be produced. When in use, you can adjust the contrast

through a 10K potentiometer.

Pin 4: RS is the register selection, the data register is selected at high level, and the instruction register is selected at low level.

Pin 5: R/W is the read and write signal line, read operation at high level, and write operation at low level. When RS and R/W are low in common,

you can write instructions or display addresses. When RS is low and R/W is high, you can read the busy signal. When RS is high, R/W is low.

You can usually write data.

Pin 6: The E terminal is the enable terminal. When the E terminal changes from high level to low level, the LCD module executes the command.

Pin 7^14: DO^ D7 is an 8-bit bidirectional data line.

Pin 15: the positive pole of the backlight.

Pin 16: the negative pole of the backlight.

Adapter board

Power supply voltage: 2.5-6V

Support 12C protocol, with backlight, jumper caps available. Set whether i has a backlight.

Insert the jumper cap to bring the backlight, and remove the jumper cap to remove the backlight.

The contrast can be adjusted by the blue potentiometer. The magic hour hand is general strong, counterclockwise minus 5,

the potentiometer is set on it, which is convenient for customers to adjust for their own use.

Device address: It can be modified by short-circuiting A0IA1/A2, the default address is 0x27.

wiring

GND: negative system power supply

VCC: system power supply positive

SDA: IIC data cable

SCL: IIC clock line
