What I am trying to do is this,· I am trying to figure out how to with BS2sx , boe, and eb500, hobbie servo, the other end hooked up to a computer for programming.

I·would like to turn my pot and move the servo on the other end.

Can any one point me in the right direction ?

    code snippets that I am fussing with.

    servo position code

    Pos VAR WORD
    HIGH 12
    PAUSE 1
    RCTIME 12,1,Pos
    DEBUG ?Pos

    this returns me a position or a result of where the Pot is.

    How would i get this to work with pulsout that gives me something i can transmit across the eb500 ?

    A quick web search revealed an instruction manual for the eb500. Do you have this manual... after setting up the eb500 you can send data via serout.

    After about three more hours of messing about I finaly hooked up a hard wire connect between my two BOE's and found that I am getting the same garbled data that was coming through the eb500.

    is there any thing special about the BS2sx ? and the serin and serout commands. ot the sx chip in general?

    Yes, the BS2sx uses different constants for the baud-rate selection.
    Check the manual -- sorry I can't be more helpful than that.

    ok new part of the question
    once I have transmitted my data accross the eb500 and have it stored in a varable how do I then send that data to a pin on the stamp?

    ok here is the code I finaly came up with.
    please look through and make sugestions comments or improvments please .


    send code
    ' {$STAMP BS2sx}
    ' {$PBASIC 2.5}
    ncount VAR Byte
    pos VAR Word
    INPUT 5
    PAUSE 1000
    SEROUT 1,240,[noparse][[/noparse]"con 00:0c:84:00:11:68",CR]
    SERIN 0,240,[noparse][[/noparse]WAIT("ACK",CR)]

    waitforconnection:
    IF IN5 = 0 THEN waitforconnection
    'DEBUG "connected",CR

    FOR ncount = 1 TO 1000
    HIGH 7
    PAUSE 1
    RCTIME 7,1,pos
    ' DEBUG ? pos
    SEROUT 1,240,[noparse][[/noparse]DEC pos,CR]
    PAUSE 25

    NEXT

    PAUSE 1000
    OUTPUT 6
    LOW 6
    SEROUT 1,240,[noparse][[/noparse]"dis",CR]
    SERIN 0,240,[noparse][[/noparse]WAIT(CR,">")]
    'DEBUG "disconnected",CR



    recive code
    '{$STAMP BS2sx}
    pos VAR Word
    'Wait for the eb500 radio to be ready
    PAUSE 1000
    Main:
    SERIN 0,240,[noparse][[/noparse]DEC pos]
    ' DEBUG DEC pos,CR
    PULSOUT 12, pos/5
    GOTO Main
