Mô Đun Màn Hình Lcd Xanh Lá Iic / I2C 1602 Cho Arduino 1602 Lcd R3 Mega2560 Vn

Supply voltage: 2.5-6V
Support I2C protocol
The power control with backlight can be set via jumpers backlight power supply is connected
The contrast can be adjusted by turn the blue potentionmeter clockwish enhanced counterclockwish weakened.potentionmeter design on the front and the convenience of constomers anytime,anywhere free adjustment
The module can cascade up to eight cascade./A1/A2 modify the device address via short circuit A0. The default address is 0x27
The standard 16X2 LCD character module (backlit / blue screen)
1602 using a standard 16-pin interface, including:
1 foot: VSS ground power
2 feet: VDD of 5V positive power
Pin 3: V0 LCD display contrast adjustment end connected to the positive power supply contrast weakest grounded power, highest contrast, the contrast is too high will produce "ghosting", by using a 10K potentiometer to adjust the contrast
4-pin: RS register select the data register, select, high and low, select the instruction register.
Pin 5: R / W for read and write signal line, a high read operation, write operation is low. When the RS and RW can write low instruction or display address when RS is high when the low RW can read busy signal when RS is high RW can write low data.
: E end of the first 6 feet to enable end, When E Duanyou high jump goes low, the LCD module execute command.
7 to 14 feet: D0 ~ D7 8-bit bi-directional data line.
15 feet: backlight power supply positive
16 feet: backlit negative supply
1602 LCD module within the character occurred memory (CGROM), has been stored in a 160 dot matrix characters graphics, as shown in Table 1, these characters: Arabic numerals, the case of the letters of the alphabet, commonly used symbols, and Japanese kana each character has a fixed code, such as the code of the uppercase letters "A" is 01000001B (41H), display module address 41H dot matrix character graphics show up, we will be able to see the letter "A . "
