Projects and Designs of Wolfgang Wieser

Digital circuits, programmable logic devices and microcontrollers, Boards which connect to a PC via the USB port (USB8bit, USB-FX2) which supersede my very old parallel port card (Latch16bit).

4 Channel Servo Controller - This is a small and leight-weight controller for up to 4 RC peripherals (such as servos) with a digital I2C interface.

USB-AtmelPrg: Wolfgang's Universal Interface Cable

USB-FX2 Interface Board (USB-2.0) - A small microcontroller-steered 16bit parallel IO interface board connecting external devices to a computer applying USB-2.0 (high-speed).

ELektronik Kompendium

Two new circuits with AVR: Universal timer and frequency clock, in addition new software for the ATTiny11-Programmer, in order to be able to program also Tiny12 and Tiny15.

ELektronik Kompendium

Two new circuits with AVR: the fluorescence indicator control with HD44780-Emulation and the simple radio clock with various indicator options. In addition a Perl Script for the RS232-zu-LCD-Konverter for the use with XMMS.

Second update: Transmitter circuit for the RS232-Interface without Microcontroller with 8 entrances, in addition the texts somewhat revises and restructures.

16-bit to seven-segment

16-bit to seven-segment 
 
"This circuit is used to represent a binary word (up to) 16-bit to seven-segment displays. Changes the binary word, the display is updated immediately. If fewer than 16 bits are displayed, the unused inputs can be connected to ground easily. A switch between six different display modes can be switched"

Rogers Embedded Microcontrollers

This page is intended to be a source of information for those interested in Motorola MC68HC05, MC68HC08, MC68HC11 and MC68HC12 Microcontrollers.

Rogers Embedded Microcontrollers

Six Digit LED Clock Display - The board is driven by a Maxim MAX7219 which has a serial interface; it can be controlled by a any microcomputer with a SPI or three output lines. The board is 2.75 inches by 6.5 inches in size; mounting four .8 inch LED displays and two .56 inch displays as well as six individual LEDs, a 7805, the MAX7219, and a five pin header.

Sleeping Beauty - Arduino Compatible ATmega1284p board

Sleeping Beauty - Arduino Compatible ATmega1284p board

The Sleeping Beauty is an Arduino Compatible board using an ATmega1284p.  The board was designed by Wayne Chu.  The size and function are the same as an Arduino UNO r3.

It has all the necessary components of an Arduino compatible UNO board but adds several devices useful for software development and education. These are briefly described below:
