Wiring and Communication:
To use a 128x64 LCD, you would typically connect it to a microcontroller (e.g., Arduino, ESP32, Raspberry Pi). Here's a typical wiring setup:
-
For I2C Interface: Only two data pins are required (SCL for clock and SDA for data), along with power (VCC) and ground (GND).
-
For SPI Interface: Additional pins are used (MOSI, SCK, CS), but communication is still efficient.
Libraries:
If you're using an Arduino to interface with a 128x64 LCD, there are several libraries you can use to simplify the coding:
-
Adafruit GFX Library: A graphics library that supports various displays, including 128x64 LCDs.
-
U8g2 Library: A popular library for working with monochrome graphical displays, which supports various resolutions and interfaces (I2C, SPI).
