I/O Bus Emulates Multiplexed Address/Data Bus - 02/15/96 EDN-Design
Ideas / Adapting off-the-shelf, general-purpose single-board
computers for real-time and other special-purpose applications can require
additional peripheral chips. Most of the Intel-compatible ICs have a
multiplexed address/data bus, and thus you can't readily interface these
ICs with a single-board computer's general-purpose I/O bus. Chips with....EDN

I˛C interface connects CompactFlash card to microController -
Maxim Application Note 4418:This application note explains how to use an
I˛C I/O extender to connect a compact-flash (CF) card to the I˛C interface
of a microcontroller. The software commands for reading and writing data
are explained. The MAX7311 I/O port extender is featured in the design
circuit. This design idea appeared in the September 1, 2006 issue of
EDN magazine. |

IBM PC Keyboard to Palmpilot Interface - Why would you want to interface the
Keyboard? The IBM keyboard can be a cheap alternative to a keyboard on a
Microprocessor development system. Or maybe you want a remote terminal, just couple it
with a LCD Module. Maybe you have a RS-232 Barcode Scanner or other input devices,
which you want to use with existing software which only allows you to key in numbers
or letters. You could design yourself a little box to convert RS-232 into a Keyboard
Transmission, making it transparent to the software.... |

IC & Capacitor Improve Isolated Supply - 09/01/97 EDN-Design Ideas
Many isolated power supplies typically use an optocoupler and a reference to provide
feedback to a controller to maintain a constant output voltage. Alternatively, you can
use an isolated flyback regulator, IC1, to....[Design Idea added 11/05] EDN is

ICOM CI-V interface with RS232 RTS to PTT - This page describes my
home-built ICOM CI-V interface. In order to connect most all ICOM radios to a
computer, an additional interface is required. The interface bridges the gap between
the RS-232 electrical levels used by the computer serial port, and the open
collector shared bus used by the ICOM radios. The interface, therefore, is not much
more than a level converter....(diagram added 05/06/07) |

Image-capture system uses USB and LabView 24-Jun-10 Issue of EDN Capturing
and processing graphical images requires manipulating data into a form that you can
use. This Design Idea describes an imaging system using a USB (Universal Serial
Bus ) image-capturing system that uses OmniVision’s 640×480-pixel, 8-bit-color OV7660
image sensor. The CY7C68013A-128AXC from Cypress Semiconductor provides a USB
interface between a PC and the image sensor (Figure 1). The control software is
written in LabView from National Instruments.... [Design Idea by Chien-Hung Chen and

Implement a nine data-bit UART on a PC - 05-Jun-98 Issue of EDN Many
µCs, such as the 8051 and the 68HC11, can support a ninth data bit on the asynchronous
serial port. This bit is useful in multidrop applications in which you can use
it to denote an address on the serial bus, as opposed to data destined for a
particular address. The UART used in IBM PCs (and clones] does….Contains several
