Lean, efficient I2C LCD Arduino library

Sam from lincomatic has released his new I2C LCD Arduino library. Known as LiquidTWI2, its a lean, high speed I2C LCD Library representing an extension of the work done by FalconFour on his LiquidTWI library, with the addition of support for Arduino 1.0+ and for Adafruit RGB LED Shield (MCP23017-based). Via the contact form.

Earthmake debuts ArduinoLCD

Earthmake has announced the release of the ArduinoLCD, a combination Arduino UNO board and ezLCD into a single product capable of accepting all Arduino compatible shields. The ezLCD is a 3.5″ TFT color LCD with 320 x 240 resolution and 65k colors. The combo may be programmed using the Arduino IDE and the Arduino ezLCD […]

USB and serial enabled LCD backpack is back in stock at Seeed Studio. This board connects HD44780-compatible character LCD screens to your USB port. It works with apps like LCD Smartie to show news, system stats, and more on an external LCD. Get USB and serial enabled LCD backpack for $16.95.

PIC12F source shared for the one-wire HD44780 LCD controller

As a follow up to the “One wire control of HD44780 LCDs” post, McLaren shared the Assembly source code for his project. Pick up the source in the forum. Assembly language source file and hex file (for 12F683) attached… Allow approximately 60 msecs after power-up for LCD initialization before sending commands and/or data to the […]

One wire control of HD44780 LCDs

Does the minimum 6 pins needed to control an LCD give your little microcontroller a sad? In the forum we’re discussing low pin-count control methods for common HD44780 parallel displays. This one uses is a simple serial UART adapter similar to our USB and Serial LCD backpack: Here’s a reasonably economical 1-pin Serial interface solution. […]

ATTiny2313 controlling a HD44780 LCD via AVR-GCC

We came across Scott Harden’s brief article describing how to control an HD44780 LCD using an Attiny2313. After a number of unsuccessful attempts with other code he found this LCD library written by Martin Thomas for use with AVR-GCC. With a few mods to the code Scott produced the above results controlling his 2×20 LCD […]

WORKSHOP VIDEO #30: Bus Pirate LCD Adapter v3 overview and demo

EEVblog brought up the Bus Pirate LCD adapter this week, so we though it was a good time to talk about the latest v3 hardware revision and do a simple demo. This is a small board that has everything needed to control and test common HD44780 LCD character displays with the Bus Pirate. The latest […]

Bus Pirate on EEVblog and 2×8 connector support on LCD adapter

Dave over at EEVblog tested an HD44780 LCD, and he used the Bus Pirate and LCD adapter in his demo. In the video he works with an LCD that has a 2×8 header, but the LCD adapter only supports a 1×16 type. Here’s a prototype LCD adapter board updated with an optional 2×8 LCD header. […]

Video player using Nokia color LCD and 8 bit AVR

Vinod S. writes about his latest project, a video player using a Nokia color LCD, ATmega32 and SD card. “I am introducing my new video player made using an ATmega32 microcontroller and Nokia color LCD. I got a 65K color LCD from an old Nokia 6030 mobile phone. I directly soldered 10 thin enameled copper […]

AVR LCD name badge using ATtiny 2313

Erik Gregg (Hank) wanted a name badge using an 16×2 alphanumeric display for use at conferences, nerdfests, etc. He constructed this simple ATtiny2313 based badge which interfaces with the LCD with a minimum of components. This project is based upon this Instructable. He took the Instructable to the next level by moving from breadboard to […]

LCD touch and button Boosterpacks are available at 43oh

Lars designed and produced these LCD touch and button Boosterpacks for the MSP430. It’s an LCD breakout with 4 tactile buttons or 4 cap buttons, depending on the version. It sits on top of the 430 LaunchPad, but can also function independently if a microcontroller is soldered on. This pack is a good component if […]

DIY Arduino 6-channel temperature monitor

Johnathan Hottell wanted a way to monitor and display the temperature readings at various points around the engine on his LB7 Duramax diesel truck. He developed this project for a six channel temperature monitor employing a bank of thermistors to monitor various engine locations. They are read each second by the Arduino’s analog pins, with […]

New liquidCrystal Arduino library

Francisco Malpartida, an Arduino enthusiast from Spain, has posted a new liquidCrystal library for Arduino. The main differences are a claimed increase in speed of LCD operations and the ability to control the LCD display via an I2C bus expander or a Shift Register Extender in addition to the usual 4- and 8-bit modes. Via […]

Cheap 1.3” 96X68 monochrome LCDs with I2C interface

Greeeg tipped us of to some cheap $3 1.3” 96X68 monochrome LCDs. They have a solderable connector with a manageable pitch of 0.6mm. A simple I2C interface protocol is used to interface with these LCDs. These are Displays from ebay are small B/W displays from the nokia 1202 and a few other models. They do […]
