PFAVR - FORTH for AVR microcontroller
8. August 2008 - 13:39 — adminPFAVR is a 16-bit implementation of the Forth programming language for Atmel AVR microcontrollers. 13Kwords of FLASH and 32Kbytes of external RAM are required, thus the ATmega64 and ATmega128 are really the only devices supported as of this writing.

Flickr images on a Nokia 6110 Color LCD
14. June 2008 - 14:01 — adminMost used are these green character displays with two or more rows to display menus, status or debug messages. With mass production of mobile phones, color LCDs get that cheap, that they can be used as replacement. To test the display, I hacked a kind of small digital picture frame, that fetches pictures from Flickr.
