Finally started a migration from my old good home-brewed page to blogsum.

Since I have the intention to keep things in chronological order, as it was (more or less) on the old site, it will take a while. Sometimes it is difficult to track down exact dates of updates on the old page. But I hope the best.

DimOS RT is a preemtive real-time kernel with EDF-scheduling for Atmega microcontorllers It is inpired by the research paper from Dan Henriksson and Anton Cervin

RGB-LED

A test application for Atmega8 at 16MHz: cycle through HSV-values with 5 independent tasks:

• 1x heartbeat
• 1x hsv2rgb converter/feeder
• 3x PWM driver/reader for each color accordingly

The UART 9600,8n1 feeds current running task, although due to its speed limitation it's not in sync with real context switches.

The last release of OpenBSD (4.8) includes a new cool feature: a monitoring mode in its audio daemon aucat(1).

Thus, this little hack visualizes anything, what is being played using this new mode, no matter where the sound data came from.
