RE: streamDevice hex format input

["Tian, Yuke" <ytian@bnl.gov>]

Hi Gorka,

 

I found if you want to read raw byte, you need to use

 

in “%4.4r”

 

as the input format. Please give a try.  The Streamdeive document doesn’t clearly mention this.

Subject: streamDevice hex format input

 

Hi all,

 

I’m using streamDevice, attempting to communicate with a device sending and receiving in hex format. I achieve to make right the sending, but I have problems with the receiving. I write the following in the protocol file:

 

##################################################################

cmd1 = \xC0\x01\xFE\x00\x00\x00\x00\x00\x00%<xor>;

c1 {

    out "\$cmd1";

#    in "\xA0\x55\xAA\x5F";

#    in 0xA0 0x55 0xAA 0x5F

#    in "%s";

    in "%*4r";

}

###################################################################

 

 

Like you could see I try different options for input, but any of those and others I try work for me. I like to have an input in hex like, 0xA0 0x55 0xAA 0x5F or A0 55 AA 5F in my soft IOC. Instead, I have the following, which could be ASCII:

 

##############################################################

epics> 2010/09/13 15:20:08.440 /dev/ttyS0 read 1

\240

2010/09/13 15:20:08.442 /dev/ttyS0 read 3

U\252_

###############################################################

 

 

What I have to write exactly for the input?

 

This is the record I use for that command. What type of record should I use?

 

##########################################################

record(bi, "$(P)$(R)C1")

{

    field(DESC, "Comando 1")

    field(DTYP, "stream")

    field(INP,  "@devwbc6600.proto c1 $(PORT) $(A)")

}

This is the st.cmd file:
