I don't think it is SWINDUS interrest to support the ledwiz. As he sells his own hardware.... but i can be wrong, just a guess. ;)

It looks like you have done some extensive work with the hardware that mala sells as well as the led-wiz. I had a couple of questions for you.

FYI I don't have anything to do with sales of MaLa hardware. But I am a volunteer for MaLa and do Beta testing of hardware and software. MaLa's hardware/software creators live in Germany and I live in Australia.


--- Quote ---1. Is the Mala hardware a common-anode interface like the led-wiz?
--- End quote ---
Yep, But on the plug the anode is provided for each LED anyway (so you can wire it how you want)

--- Quote ---2. The IO-Warrior specs call for a 6MHz ceramic resonator across pins 21 and 22. I don't own an led-wiz just yet, but all I can see on the led-wiz board is what looks like a simple capacitor on the end of the controller chip. Is that all it is or is it a ceramic resonator?

They appear to be both a 6 reso

--- Quote ---3. Any idea what the driver chips are on the led-wiz?  Could they be 2803s like the mala hardware uses?

The chips on the Wiz are not labled. Any questions about the LedWiz really should be directed to RandyT (from GGG). Sorry

There is some truth in that, not really for financial reasons as I understand they make very little money from the hardware as it is hand made at the moment.
I get the distinct impression that the lack of incentive to support the Wiz is more to do with the fact that a lot of time of effort was spent to support their own hardware. The LedWiz is controlled differently so a lot of time would have to be spent again. So not much incentive really I guess.

Anyway when I discovered this 'Chip swap for $20' I thought I would tell the world as it could be a solution for a lot of users (be it temporary or permanent) as the software controll of the LEDS and LCD in MaLa works well and is easy to set up.

This worked out to be a perfect solution for me. Almost too easy! I am using it to control the 32 LEDs on my CP. The chip swap was a piece of cake and the modded LEDWiz was recognized by my XP system and the MaLa software with no problem. A true plug and play solution. Thanks for a great find. Here is a pic of the completed install.
