The PCF8578 is a low power CMOS1 LCD row and column driver, designed to drive dotmatrix graphic DISPLAYs at multiplex rates of 1:8, 1:16, 1:24 or 1:32. The device has40 outputs, of which 24 are programmable and configurable for the following ratios ofrows/columns: 32¤8, 24¤16, 16¤24 or 8¤32. The PCF8578 can function as a stand-alone LCDcontroller and driver for use in small systems. For larger systems it can be used inconjunction with up to 32 PCF8579s for which it has been optimized. Together these twodevices form a general purpose LCD dot matrix driver chip set, capable of driving DISPLAYsof up to 40960 dots. The PCF8578 is compatible with most microcontrollers andcommunicates via a two-line bidirectional bus (I2C-bus). Communication overhead isminimized by a display RAM with auto-incremented addressing and display bankswitching.

This article is a very simple introduction writing a Windows Form application for the Microsoft.NET framework using C#. The sample application demonstrates how to create and layout controls on a simple form and the handling of mouse click events. The application DISPLAYs a form showing attributes of a file. This form is similar to the properties dialog box of a file (Right click on a file and Click on Properties menu item). Since attributes of a file will be shown, the sample will show how to use File IO operations in .NET framework.

The aim of this application note is to show to scan the 4x4 matrix keypad multiplexed with a four 7-segment display. The software attached to this application note scans the pressed key and DISPLAYs it on the multiplexed 7- segment LEDs. This application note makes obvious Interrupt capability of the STR710 device to offer a better key scan .

Magenta Systems Internet Packet Monitoring Components are a set of Delphi components designed to capture and monitor internet packets using either raw sockets or the WinPcap device driver. Hardware permitting, ethernet packets may be captured and interpreted, and statistics maintained about the traffic. Uses of packet monitoring include totalling internet traffic by IP address and service, monitoring external or internal IP addresses and services accessed, network diagnostics, and many other applications. The component includes two demonstration applications, one that DISPLAYs raw packets, the other that totals internet traffic. The components include various filters to reduce the number of packets that need to be processed, by allowing specific IP addresses to be ignored, LAN mask to ignore local traffic, and ignore non-IP traffic such as ARP.
