Personal Stuff (in German)

• Long, long years ago, i had the time to play a lot with semiconductors and microcontrollers. Here is a copy of my microcontroller-page which describes how to interface an Atmel 89Cx051, and how to connect peripherals like I2C bus devices, LC displays, stepper motors etc. Die Microcontroller-Seite (in German). Please note that the page is a little out of date. I do not have the time to update it, or to answer questions regarding microcontrollers.
