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 character… |
Excel offers painless LCD initialization: 09/20/2001 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. Alternatively, you

Seven segment LCD uses two wire interface : 09/04/03 EDN-Design
Ideas / You can connect seven-segment LCDs using only a two-wire
interface (Figure 1). The two-wire interface may be at the
field-effect, direct-drive LCD or at a serial interface (such as
I2C) that uses an eight-pin microcontroller. The design in
Figure 1 uses an Atmel (www.atmel.com) ATtiny12 microcontroller,
IC1....
