Martin Thomas shows us how to interface Atmel AVR witg graphic LCDs:

This is a C-library for avr-gcc/avr-libc to access SED1520-based graphics-LCDs. The modules used to develop the library only support “write to LCD”, read-modify- write on the display RAM is not possible. So this Library uses a “framebuffer” which holds the display-content in the AVR’s SRAM. For a 122*32 pixel display around 500 Bytes of SRAM are occupied by the buffer. The library does of cause support modules which can be read in “write-only-mode” (tie the R/W-Pin to GND).

SerialMonitor

ARPix has posted this instructable on constructing an external serial monitor device using the Atmega328 MCU and a graphic LCD. It allows a user interface to set the serial baud rate and start/stop functions using tact switches.

Sometimes I needed an external serial monitor like the Serial Monitor in the Arduino Editor, to see what is going on. So I made one. For the ESM I used an Atmel Atmega328 because it have an internal SRAM with 2KBytes. It’s necessary for the big data processing. So you need more than 1KByte SRAM.

This project consist of Arduino board, serial TFT LCD 128×160 display, DHT22 sensor and obviously bread board and jumpwires.

Project features:

  • Temperature measurements : -40 – 125° C, +/- 0.2° C
  • Humidity measurements : 0 – 100% , +/- 5 %
  • Update rate 2 s
  • Humidex(“describe how hot the weather feels to the average person, by combining the effect of heat and humidity.” ) is calculated based on measurements
  • Humidex digits color varies and represents affect on humans.
  • Black and white display themes.

hackshed.co.uk has a tutorial on how to interface a Nokia 5110 LCD to Arduino:

We purchased one of these very cheap, very cool 84×84 LCD backlit screens off of eBay a couple of weeks ago.

It’s a very nice product for adding visual elements to your projects at a very low price. We paid £3.89 for the screen and it was delivered a few days later.

Take a look below for connection instructions and example code from Adafruit on how to get this up and running with your Arduino.

4,3″ and 7,0″ LCD “Cape” connected to a BeagleBone module can transform this microcomputer to a standalone module with a graphic output. 

Microcomputers BeagleBone have earned a global popularity and the community of Linux and Android OS users know them well. Accessories (options) to these modules further enhance and simplify their usage in praxis. To these accessories also belong two new LCD modules form company 4D Systems – 4DCAPE-43T and 4DCAPE-70T. LCD modules are suitable for a newer version – BeagleBone Black (BBB) and they are not suitable for the BeagleBone white.

Connecting these LCD modules we gain a complete computer suitable for control of various devices. Color displays provide a quality picture, well legible even at a relatively strong ambient light. 4DCape-43T, 4DCape-70T as well as BeagleBone Black are our standard stock items. 7,0“ type offers besides a bigger display area also an access to BeagleBone pins thanks to additional connectors on the rear side of the display.

A tutorial on interfacing LCDs (liquid crystal displays) with Arduino. We take a look at libraries and the role they play…and the potential issues, errors and troubleshooting involved.
We look at several types of displays but concentrate on the 4×20 Sparkfun serial enabled LCD display.

This is the Nokia 5110 84X48 display that was used on millions of phones in the late 90′s. In this video, I show how to connect the Nokia 5110 LCD to an Arduino Uno, import the correct libraries to the Arduino IDE, and write code to generate text and graphics on the display.

Working on a project where you need to display something (like data/debugging info)? Why not use an LCD! In this video, I go through various aspects of controlling the device with an Arduino, including setting different types of cursors, toggling the display and even creating custom characters!

If you want to go to the heart of a thing, then LCD TFT displays Winstar are right for you.

It can be said, that nowadays in the most cases it´s cheaper and faster to use a ready-made graphic module. From this category we keep in stock for example eDIP TFT modules from company Electronic Assembly, intelligent modules from company 4D Systems or also a hot novelty from company FTDI – technology EVE.

Naturally, despite this, it´s possible, that simply a ready-made intelligent module which would meet all your demands simply doesn´t exist. For these cases we have for you color TFT LCD displays from company WinStar (Taiwan). In our standard stock offer can be found displays WF43GTIB (4.3“, 480×272), WF57ETIB (5.7“, 320×240) and WF70HTIF (7.0“, 800×480). Displays incorporate a modern display controller SSD1963 supporting various communication formats, that´s why they offer so to say a free hand and a full control at your design. An idea about possibilities of these displays will give you an application note SSD1963 as well as datasheets WF43GTIBEDBT0 WF57ETIBCDBT0 and WF70HTIFGDBT0.

Company Winstar produces a large amount of various versions of displays, also without controllers.
