Hi Gorka,

Please use the subject line. Otherwise your request may be ignored.

You can use protocol(param1,param2...) with up to 9 parameters (which must neither contain space nor comma at the moment, sorry). No space allowed before ( or inside ( and ).

The parameters appear as $1 ... $9 in the protocol. (Within quotes the $ must be escaped: "\$1" ... "\$9".)

I would write your example as follows:

field(INP, "@devwbc6600.proto c4(0x04,0x57) $(PORT) $(A)")

c4 {
  out 0xc0 0x04 0xfb $2 $1 0x00 0x00 0x00 0x00 "%<xor>";
...
}

You probably want to use macros for LO and HI:

field(INP, "@devwbc6600.proto c4($(LO),$(HI)) $(PORT) $(A)")

LO and HI may as well be specified in decimal here if you like.

By the way, instead of "c4" I would also give the protocol a name that someone who is not an expert in the wbc6600 (?) can understand.

Hello everyone,

Using streamDevice, How can I run the command dbtr like a function with parameters? Something like:

Function (parameter 1, parameter 2)

How do I have to write the protocol and record? There are currently as follows:

HI = \x04;

LO = \x57;

cmd4 = \xC0\x04\xFB${HI}${LO}\x00\x00\x00\x00%<xor>;



c4 {

out "\$cmd4";

in "%*4r";

}





record(bi, "$(P):$(R):C4")

{

field(DESC, "Command 4")

field(DTYP, "stream")

field(INP, "@devwbc6600.proto c4 $(PORT) $(A)")

}



What I want is not to specify the values of the variables HI and LO in the archive .proto. I want to give them values when I call the command dbtr (another command to process the records?), to give these variables the hexadecimal value I want, each time I run the command.

Thanks in advance,

Gorka
