Does anyone know how to use HSEROUT to talk to PLX-DAQ? I am getting a RX from PLX-DAQ
but apparently my format is wrong or maybe it just doesn't work with a PIC.
Thanks, Don

Hi Don,
I have not tried using that, but others have been successful. Here is one thread that talks a little about it.

Yea I tried that but couldn't get it to work.Quote:

Have you tested your hserout, to be sure you have the right baud rate, etc?
There really is no code just the defines and HSEROUT. Bare minimum. It connects and I can see the little green box with the "R" in it flash red when I reset the pic. I can receive no problem with hyperterminal and the terminal in Microcode Studio. I have used Debug and Hserout2 with those two with no problems. I think it might be a format issue.Quote:

BASIC Stamp Code
BASIC Stamp code is used to illustrate using the Simple Data with Plotting sheet of PLX-DAQ.
- This program sends the value of variable X and the BASIC Stamp SIN value of X.
SEROUT sPin,Baud,["DATA,TIME,TIMER,", DEC X, ",", SDEC SIN X, CR]- The current row is read, and when exceed, will reset the row back to 2.
SEROUT sPin,Baud,["ROW,GET",CR] ' Request Row
SERIN sPin, Baud,200,TimeOut,[DEC Row] ' Accept returning data with timeout
IF Row >= 300 THEN SEROUT sPin,Baud,["ROW,SET,2",CR] ' If Row is or exceeds 300, set row back to 2
- Note that SEROUT 16,84 (sPin and Baud values) is used to send data. This is equivalent to DEBUG but prevent the DEBUG window opening.
- SERIN 16,84 is used, which is equivalent to DEBUGIN, but provides for timeouts to be used so that the program does not lock up if there is a problem.
- When using the DATA directive to send multiple values, a combination of strings and values is needed to force commas between values.
I seen that and tried a 13 for the carriage return.......Quote:

Maybe they really mean CR ??Quote:

Yeah but typewriter are so hard to find theses days ;)
Not sure they have some SMD one?
so like this huh?Quote:

Hmmmm..... Maybe
SMD?? I think I have one of those in the garage......
I'll go get it and try it....be right back
I don't think hello is a directive.Quote:

HSEROUT ["DATA,","1,","2,","3",13]
or:
HSEROUT ["DATA,",DEC x,",",DEC y,",",DEC z,13]
Those will show in different columns. If you want more rows, then more like their basic stamp example.
Did the basic stamp send in True or Inverted mode?
Good point Dave,Quote:

Since Don said he could read it in hyperterminal, I assume he is using a max232 device. I also assume he meant he tested hyperterminal with hserout. So maybe it is just in the wrong format.
From another page in the help file:
So maybe this is the hang up?Quote:

It would be great to see a solution, and write up in the Wiki area (Hint, Hint).

Thanks Walter....
Code:HSEROUT ["LABEL",",","Don's",",","Test",13]
PAUSE 10
Loop:
FOR x = 1 to 5
HSEROUT ["DATA",",","Hello",",","World",",","Goodbye",13]
PAUSE 5000
NEXT x
PAUSE 10000
HSEROUT ["CLEARDATA",13]
GOTO Loop
