Hi all
I have pre loaded beam effects loaded on my laser machine It comes on when no lap top is connected.
Is there any way I can Chage the Beams to pictures or is it some kind of pre factory test or somthing>
Any ideas???

You probably have the same DMX / ILDA controller that everyone else has that came with the scanners. That's a ROM chip. I don't think you can change it. You might be able to replace it with some other set of pre-defined graphics.
James. :)
If you have a programming board, and the source code for the chips, you _may_ be able to modify it. I have been thinking the same thing, but not sure hows it works.

After a little researching, it appears this will actually be quite easy to do. I am thinking about doing a little reverse engineering along with Dave to try figure this thing out. It seems its just a simple CMOS flash chip ....

They are probably nothing more that tables of points so I think you are right it should be 'easy' to do for some folks. Good luck, consider releasing an app that is able to load ilda files into the ROM binary file, and then another app that came with the ROM programmer can re-flash the ROM.
Maybe there is even a way to re-flash the ROM in-circuit? :D
i have a few of these if it would help i can send you one to hack
what microprocessor is it? It may have a bootloader, if that is the case, it may not have the security bits set and it would not be hard to pull the code out and hack it. THe frame data files would be obvious.Quote:

^^
And I vaugley remember a member talking about hacking the firmware(very well written assembler BTW!!!) to add DMX capability to the ELM Chan circuit
the ones i have now use an stc chip but i have seen them with an atmega chip
ATMEGA I can read and decompile. I dont have a SDK for ST :-(Quote:

as long as the rom is readable, as you said decompilation isn't necessary. But is it worth it? These things probably can't hold more than a few hundred frames and there are DACs out the that can hold many full shows on an SD card.
This is the chip that needs to be programed Im guessing though:confused:
What you think? its huge
Yeah thats more than likely the memory chip.
Thats a standard microcontroller, your looking at the whole control computer and memory on a single chip.Quote:

If the security bits are not set, I'll see what I can do.

having used one a few weeks ago, the effects on them are not that great. Its the challenge of it. Maybe we need to do a group run of Elm Chan boards?Quote:

Something like a RIYA DAC device might be better. They support SD memory, I think up to 2 gigs and can run standalone. They also have some sort of DMX support.
