PIN Explanation:
Step 1: VSS is the ground power source
Pin 2: VDD connected to 5V positive power supply
Step 3: V0 is the contrast adjustment end of the LCD display
Step 4: RS is for register selection, select data register for high level, and select instruction register for low level.
Step 5: R/W is the reading and writing signal line, which is used for reading operations during high battery life and writing operations during low battery life. When RS and RW are both low level, instructions or display addresses can be written. When RS is low level, RW is high level, busy signals can be read. When RS is high level, RW is low level, data can be written.
Pin 6: The E end is the enable end. When the E end jumps from a high level to a low level, the LCD module executes the command.
Pins 7-14: D0-D7 are 8-bit bidirectional data cables.
Pin 15: Backlight power positive pole
Pin 16: Negative pole of backlight power supply
