Hello!

 

Question: I am attempting to aquire data from an H48C using the SX28AC/DP and coding in SX/B.  This is my first time using the controller/language and I'm having a bit of trouble.  I've been using the sample code given on the site using BS2, but have had to modify it some...

 

I call to subroutine "get_h48c" from my main statement.  Subroutine "get_h48c" looks like this:

 

Get_H48C:
   RB = 0
                        CS = 0
                        SHIFTOUT         DIO, CLK, MSBFIRST, VRef\3
      INPUT RB.1   
                        SHIFTIN          DIO, CLK, MSBPOST, rvCount\8
                        SHIFTIN          DIO, CLK, MSBPOST, rvCount2\5
                        CS = 1
                        
   PAUSE            1
   
      RB = 0
                        CS = 0
                        SHIFTOUT         DIO, CLK, MSBFIRST, axis\3
     INPUT RB.1
                        SHIFTIN          DIO, CLK, MSBPOST, axCount\8
                        SHIFTIN          DIO, CLK, MSBPOST, axCount2\5
                        CS = 1
RETURN

 

I've verified with my scope that there is data flying around everywhere on my DIO line, but variables rvCount, rvCount2, axCount, axCount2 all stay zero.  I'm using SEROUT to send the data to an XBee, and I've verified that that operation is working correctly.  It seems that I'm not accessing the information correctly.

 

So here's the question...

 

Does anyone see anything obviously wrong with what I'm doing here?

 

any help would be greatly appreciated.
