• LCD Interfacing Reference Page - The most common type of LCD controller is the Hitatchi 44780 which provides a relatively simple interface between a processor and an LCD. Using this interface is often not attempted by inexperienced designers and programmers because it is difficult to find good documentation on the interface, initializing the interface can be a problem and the displays themselves are expensive. The purpose of this page is to give a brief tutorial on how to interface with Hitatchi 44780 based LCDs. It tries to provide the all the data necessary for successfully adding LCDs to your application.

• Parallel interface for SII G1226 LCD - G1226 is black&white dotmatrix LCD with 128x64 pixel resolution. Parallel port adaptor was implemented on "vero" board mostly with surface mount components (size 1206) but it can be implemented with throughole components also. Prototype was proven to be fully working with minimal test SW written for MSDOS.

• Why a Graphics LCD is the Best Choice for Many Text-only Applications - The benefits of a graphics display are obvious--it can show graphs, icons, and bitmapped pictures. What's not obvious is that the right graphics display is also the best choice for many text-only applications. This article will contrast standard alphanumeric LCDs with the new G12032 serial graphics display from Seetron (Scott Edwards Electronics Inc.).
• WinAmp Matrix Orbital/Crystalfontz/HD44780 LCD Plugin - This WinAmp plugin in combination with a Matrix Orbital LCD / VFD, Crystalfontz or a HD44780 display makes it possible to display the current song name and additional status information on the display. The LCD displays inerface to PC parallel or serial port depending on the LCD model.   
• Processor's PWM output controls LCD/LED driver - The PWM (pulse-width-modulation) output available from many microprocessors is based on an internal 8- or 16-bit counter and features a programmable duty cycle. It is suitable for adjusting the output of an LCD driver.

• Car Message Display - The purpose of this circuit is to display various symbols/messages to the car driver travelling behind you. It uses 1024 LEDs to form a 32 x 32 matrix display. A total of 12 symbols/messages can be displayed, 4 of them being user-definable by using a visual basic utility tool connected to the rs232 port of a PC.
