Trumba's Electronic Page

Author: The electronics isn't my top field of interest so don't expect too much from this page.. However, designing electronic circuits based on digital devices is my specialty.

• Documents - mostly written by me
• Links - interesting stuff from all around world

Docs:

• Basic characteristic of digital integrated circuits (74xxx and 4xxx family)
• ISA bus (pin description)
• Parallel port by Kris Heidenstrom (pins and description of PS/2,EPP,ECP mode)
• How to make your own AT card (PIO & DMA data transfer,connecting IRQ lines,..)
• EPROM, EEPROM and GAL programmable logic devices(simple and high performance programming theory)

How to do

Tomi Engdahl page: very useful page at which you can find docs on various things such as:
electronic circuits (audio,video,computer,data communication circuits,..),
description of opamps (LMxxx), 555 timer chip,MAX232 chip for RSs232 communication, there is also description of PC-hardware: ISA,PCI bus, Plug'n Play technology...
Electrical Engineering Circuits Archive is very rich site with many electronic schemes
Circuit Cookbook WWW page: It contains a great variety of files of interest to Electrical Engineering students and electronics enthusiasts (various el. schemes).
