1602 uses a standard 16-pin interface
Pin 1: VSS is the ground power
Pin 2: VDD connects 5V positive power
Pin 3: V0 is the contrast adjustment terminal of the liquid crystal display. The contrast is the weakest when the
positive power is connected, and the contrast is the highest when the power is grounded. When the contrast is
too high, it will produce "ghosting". When using it, 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 RW are both low level, the command or display address can be written.
When RS is low level and RW is high level, the busy signal can be read.
When RS is high level and RW is low level, data can be written.
Pin 6: End E is the enable end. When end E changes from high level to low level,
the LCD module executes the command.
Pins 7 to 14: D0 to D7 are 8-bit bidirectional data lines.
Pin 15: Positive backlight power supply
Pin 16: negative pole of backlight power supply
