EB062 RS485 and DMX

[rene]

Hi boys and girlss,

Question about the RS485 EB062 board.

1: Will it be possible to use this as DMX slave ..
2: Does anyone have an example program of a DMX slave, to help me understand how to use it.

Strange, nothing in this forum about DMX slave's.
Given DMX is approximately equal to RS485 and a widely used protocol there most be someone out there with a solution.
Or is a DMX slave too complex for flowcode to handle.

What I want to do:

Receive DMX signal from master at hardcoded slave addresses.
Controlling stepper motor CW adress byte => 10 <50 and CCW adress byte> 60 <100
Simple right?
I use the 16F628a 20mHz xtal or the 16F877

 
I love to hear from you,

René

Hi Rene,

Yes you should be able to use this board for a DMX slave application. You may need quite a fast micro eg a 18F PIC running a 48MHz or maybe a dsPIC depending on what you need the slave to be capable of doing. Start out with the 16F and see what you are able to achieve. The RS232 component and the RX interrupt may help to make things work a bit more reliably.
