So if you wanted 3 LCDs, for example, they would all have the same data and clock pins, but the latch pin would be different, for 5 pins total. This library does not use the Hardware SPI library, which means you can use any 3 pins! However, if you are using the hardware SPI port (such as for Ethernet, WiFi, an LCD, etc. etc) you cannot share those pins with this LCD! The first thing you will. A 16×2 character LCD, for example, has an LED backlight and can display 32 ASCII characters in two rows with 16 characters on each row. If you look closely, you can actually see the little rectangles for each character on the display and the pixels that make up a character. Each of these rectangles is a grid of 5×8 pixels.

Why I2C (IIC) Type LCD? If you plan to add a simple readable interface in your next project. alphanumeric LCD may be the most preferred one due to various factors such as low cost, easily programmable, having no limitation of displaying special & even custom characters.. But to use it directly with a microcontroller, you would need atleast 6 pins - RS, EN, D7, D6, D5, and D4 (with R/W pin. If you have a datasheet or sample code that uses 8 bit address, you'll want to drop the low bit (i.e. shift the value one bit to the right), yielding an address between 0 and 127. Applications. I2C is common in segment LCDs and different types of sensors. I2C is lower speed than some other protocols but is still very effective in communicating with multiple devices on one bus. Popular.
