[Sdcc-user] SDCC and receiving DMX512

[DD <d2...@xn...>]

Hi,

I want to wrote a receiver for DMX512 packets (it is an strange serial =
comunication).
Does anybody has some experience with this ?
I found some directions at =
http://www.8052.com/users/dmx512/recieve.phtml and those are wrotten =
below.
Can somebody give me a sugestion how would look this in SDCC C ?

"Receiving DMX 512 is very easy. The basic Idea is to set the UART in 9 =
bit mode, and look at the ninth bit. If it is a "0" we are still in the =
"Make before break" if it is "1" we have a valid data byte. "


Thanks.
Daniel
