Interfacing:
A 128x64 COG FSTN LCD can interface with microcontrollers through various methods, including parallel or serial (I2C/SPI) communication:
-
Parallel Interface: Involves multiple data pins to transfer the information, typically used in older or high-speed applications.
-
Serial Interface: A more modern approach where only a few pins (typically 2–4) are used for communication, making wiring easier and reducing complexity. I2C or SPI are commonly used.
Example Wiring (Using I2C for 128x64 COG FSTN LCD):
If the 128x64 COG FSTN LCD uses I2C, you can wire it as follows:
-
VCC → 5V (or 3.3V, depending on the display's voltage requirement)
-
GND → GND
-
SDA → A4 (on Arduino Uno)
-
SCL → A5 (on Arduino Uno)
