The freescale S08JS series is one of the lowest cost microcontrollers with a hardware USB implementation. The availability of free C development tools (SDCC and Codewarrior) make the S08JS a great candidate to develop all sorts of inexpensive USB gadgets. microJS is a fully functional S08JS minimal system on a PCB less than a square inch. The board headers can be plugged into a breadboard for prototyping or soldered to another PCB for a permanent placement.
After more than a year of development and 2 release candidates, the SDCC team has released the new 3.0.0 version of this great multi platform cross compiler for MCUs. This version supports: 8051, DS390, Z80, HC08, and PIC MCUs.
Besides the numerous bug fixes here is a list of the important changes since the release 2.9.0 (list taken from SDCC website):
The rewrite is based on an implementation of the AAN (Y. Arai, T. Agui, and M. Nakajima) IDCT algorithm plus some optimizations based on extra information on the coefficient matrices provided by the RLE decoder.
This patch will enhance the X.org 7.1 Matrox Millennium II driver to support the X video (Xv) extension (extremely useful for playing DVDs and other video formats). The extension is implemented as a CPU to Frame Buffer YUV scaling ILOAD. A true overlay was not used because of a Millennium II hardware limitation that would reduce the maximum usable frame buffer to only 4Mb.
