Display bit-map images on small-graphic LCDs - 11/19/98 EDN-Design Ideas NOTE
: File contain several designs. Scroll to find this one. Combining a high-level language, such as Microsoft Windows, with low-level assembly code or C++ code allows you to display perfect bit-map pictures on your small-graphic LCD screen. You can use Microsoft Paint or any other bit-map-generating program to define and edit the picture. Unlike segmented and alphanumeric LCDs, small-graphic LCDs are fully graphical and can display logos, graphs, or any other image in addition to numbers and characters. The main hurdle to upgrading to this type of display is the software necessary to display the bit-map pictures.__ Circuit Design by Todd Fitzsimmons, Densitron Corp, Santa Fe Springs, CA

DVI/HDMI Decoder - From the day i received my beagleboard rev. B7 i was missing an easy way to use the digital video interface with a small LCD screen. Many people seem to have the same problem and often end up with big and expensive adaptors. Further indication that this is a common problem comes from the fact that the latest incarnation of the beagleboard includes a way to directly interface to the OMAPs parallel video interface. Unfortunatately this only provides 1.8v signals and still needs a converter to interface to the 3.3v signals most raw LCD use. __ Designed by Till Harbaum <Till @ Harbaum.org>

EE 491 Senior Project Digital Oscilloscope Cornell University 2000 - My senior project is to design and build a digital oscilloscope for Professor Land. This project involves a number of design challenges. On the analog side, I need a fast, low noise A/D converter. In addition, the circuit requires a -20V bias from a 5V supply. In the realm of digital, it involves interfacing two micro-controllers with each other, an LCD display, and an analog to digital converter. With such a broad range of challenges, I searched for help from my professors and contacts I made on the web. I was successful in getting __ Designed by Reid Gurnee
Embedded Processor Directly Drives LCD - 01/09/03 EDN-Design Ideas Driving a bare LCD does not necessarily require specialized interface circuitry or peripherals. This design idea describes an alternative drive scheme, which you can easily implement using the general-purpose outputs of a microcontroller. Many embedded-system applications need to interact with a user by displaying simple numeric or alphanumeric characters__ Circuit Design by Daniel Malik, Motorola, Czech Republic
ErICsson Cell Phone Display GA628 - The GA628 display provides a 12 character alphanumeric display , some icons in the second line and power consumption of some 100 uA. It can easily be connected to the hardware, simply by soldering some wires. The only disadvantage is , it needs a 3.3 V power supply and something around 5.6V. However, this code and the MSP430 provides a clock for a simple charge pump, realized with 3 diodes __ Designed by Robert Tyrakowski
Excel offers painless LCD initialization - 09/20/01 EDN-Design Ideas To display a font or a symbol on an LCD, you need to convert the desired character into numerical data. Creating the data for an entire font set requires specialized tools; even with these tools, the task can be daunting. Alternati__ Circuit Design by Alberto Bitti, Eptar, Lugo, Italy
Fourth Generation of LCD Backlight Technology - AN65 Linear Technology This publication, LTC's fourth effort devoted to LCD backlighting in as many years, treatssubject comprehensively. The text considers lamps, display and layout induced losses, circuitry, efficiency related issues, optimization and measurement techniques. Twelve appended sections cover lamp types, mechanical design, electrical and photometric measurement, layout, circuitry and related topics. __ Linear Technology/Analog Devices
GPS LCD Display Project - This is a project that I started back late 2003 when I just starting to learn PIC programming. I wanted to building something that actually did somthing useful. This project is based on a PIC16F84. I actually came up with this idea and then after doing some searching I found that a few people had the same idea. But, I wanted to build my own that I could call mine, developed by me. The whole idea is, I have several GPS units with no display __ Designed by Jason KE4NYV from Roanoke, Virginia

Interface LCD with ease - 04/27/00 EDN-Design Ideas Alphanumeric LCDs find use in various embedded systems. In these systems,µCs often lack I/O resources, so you must make optimum use of the available resources. LCDs have a bus-oriented interfacing structure, which consumes 11 I/O lines (eight data lines and three control lines). You cannot always afford to spare this many I/O lines. __ Circuit Design by Bharat Mehta, Space Applications Center, Ahmedabad, India
