Adding a LCD to any project immediately kicks it up a notch. This tutorial explains how to connect a inexpensive HDD44780 compatible LCD to the raspberry pi using 6 GPIOs. While there are other ways to connect using I2C or the UART this is the most direct method that get right down to the bare metal.
This technique:
- allows for inexpensive LCDs to be used
- does not require any i2c drivers
- won't steal the only serial port on the Pi.
The example python code sends date, time and the ip address to the display. If you are running a Pi in headless mode being able to determine the IP address at a glance is really handy.
To Follow This Tutorial You Will Need
- Standard LCD 16x2 + extras
- Adafruit Pi Cobbler - follow the tutorial to assemble it
- Half or Full-size breadboard
- Hook-up Wire
- A Raspberry Pi
 |
You can use nearly any character LCD with this tutorial - it will work with 16x1, 16x2, 20x2, 20x4 LCDs. It will not work with 40x4 LCDs |
