Looking for DMX512 schematics

[RussMartin]

I am looking for some generic DMX512 encoding and decoding circuits. Any suggestions?

Look for RS485 instead, to get a circuit.

The decoding is done in software. (well for a PIC it is).

i think not so eassy, (250kb11bit/specialstart-stop timing)....

give as some links if this is so easy....

I'm verry interested...

... googling you can find only asm stuf, with wery reserved explanation..
i think transmit is posible with asm-software sending routine combined with basic logic....

but for reciving, if someone know technics for capture (firstline bracket)
this shud be interesting post...

Thanks, Darrel!

I can handle RS485 with a Maxim product. I should have put the question differently.

Can someone point me to some generic software?

If you do a search of this forum you will find some snips of code. Beyond that there is ASM code if you google. Keep in mind that there is more than one way to successfully decode DMX. Each method has its pros and cons. Make sure you have an in-depth understanding of the protocol before you begin.

Thanks, ShoKre. I already have an ENTTEC open USB interface for the transmit side, so I'm looking for ways to do the receiving.
