Open DMX USB

Linux Driver for ENTTEC Open DMX USB dongle

Open DMX USB is an open USB to DMX dongle hardware design developed by Enttec. The Open in Open DMX USB refers to the fact that everybody is free to use the design and produce its own USB DMX Dongle without paying any licenses. Since this fits the Linux philosophy I wrote a small Linux 2.6 kernel driver to make it possible to use the dongle under Linux. Getting the Source Code The source code of the driver is now hosted as dmx_usb_module on GitHub. [Read More]

RGB LED Display test

First test of a new RGB LED display for a train in Canada. The display has 16 x 144 high power RGB LED’s to make sure it is readable in bright sunlight.

MPC8XX BDM Debugging Library

Warning: This project is from the last century (round 1999) and is probably not useful anymore (who still has a PC with a lpt port?), but I keep it here for historic reasons. The MPC8XX Library is a library to control a Motorola PowerPC processor of type MPC8xx via its BDM debug port. It is based on the GDB patch written by Frank Przybylski of VAS GmbH. The main difference with the GDB patch by Frank Przybylski is that the BDM functionality is put in a shared library and so can also be used by other applications like, for example, a FLASH loader or an automated board test program.
