Interface Definition:

Standard 16X4 LCD character module, 1604 uses a standard 16 pin interface, among which:

● Pin 1: VSS is the ground power supply

● Pin 2: VDD connected to 5V positive power supply

● Pin 3: V0 is the LCD contrast adjustment terminal. The contrast is weak when connected to the positive power supply, and the contrast is weak when connected to the grounding power supply. If the contrast is too high, "ghost" will be generated. When used, the contrast can be adjusted through a 10K potentiometer

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

● Pin 5: R/W is the reading and writing signal line, which is used for reading operations at high power levels and writing operations at low power levels. 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 high level to low level, the LCD module executes commands.

● The 7th to 14th pins: D0 to D7 are 8-bit bidirectional data cables.

● 5 pins: positive pole of backlight power supply

● 6 pins: negative pole of backlight power supply
