Electronics
Today, electronics are inseparable connected with computer technology.
Even simple applications are making use of microcontrollers, GALs,
CPLDs or FPGAs. And thats good in my opinion, because the use of such devices
makes it possible to make cost effective, but very powerful designs of such apps.
On this page, you can have a look on some of my hardware-projects.
It is often not possible for me to put a more detailed description of every
project in here, because of the complexity and the lack of time I have.
If you are interested in getting more information on a special project,
you can send an eMail to me.

BDMDebug V1.00 released
This is a powerful Windows based (sorry for this!!!) BDM Debug Tool for Motorola ColdFire CPUs. If you're a developer of hardware designs using this type of CPU, this tool is a "must-have"... :)

Now I can program my ppQBox in C!!
My brother Christian succeeded in making a GNU C ColdFire cross compiler for my SUN.
But this is only the halve thing. The output' ELF-file is not a directly runnable executable
file. The platform using it needs a loader for it.
After about 2 days of searching for ELF-manuals, analyzing the output and programming the
loader I'm now happy to tell you, that I now have no problems to run C-programs on my
ppQBox. Now it should be much more easy to go on with developing the QOS... my own Operating System for the (pp)Qbox... :)
After finishing the network-hardware and adding a small speaker to the board (for some noisy output... :) ),
I'm now working on the network software between my Amiga and the ppQBox. It's development state is about 75%, I think.
I already have packet transmission between both computers and looking forward to finish the whole thing in some days.

BDMDebug finished
|
This my ColdFire BDM-Debug interface control program. I had to program it for Wind*ws because I get
the needed DLL-file for controlling the interface only there.
I'm sure I will make later an Amiga-port of this.
I will release this tool it in the next days.
More about it you find here.

The ppQBox mainboard!!
|
Jippieh!! :) 3 weeks after creating the CPU-board, I successfully finished the
mainboard for my ColdFire computer!
|
The Board has a lot of interesting features: 256kB
buffered (GoldCap) high-speed SRAM, 1-64MB PS/2 DRAM, network interface for
data exchanges between my Amiga and the ppQBox, programmed GAL's for some IO, two
proprietary expansion slots for additional hardware (HardDisk, Sound, IO, GFX, PCI-Slots).

Fantastic ColdFire results: The first working CPU-board!
This picture is a photo of the soldered and
finished board!
You can read a detailed description of the development process
of it here.
