I am very new to SX chips and SX/B.  I am trying to interface to a MAX3100 UART chip and I am having some difficulties.

 

I found some BS2 code to do this in the BS2 forum, and I am trying to adapt this program to SX/B.  I am attaching both programs (the older BS2 that someone else wrote and the new SX/B that I have attempted to write).  After I get past this challenge, I want to use the MAX3100 for a IRDA interface to an old Palm keyboard that I have, but first I need to be able to communicate between the SX and the MAX3100.

 

So far the code I created only tries to send the MAX3100 a configuration command and then immediately read back the MAX3100 configuration registers.  From what the BS2 code says, I should be getting back the exact same bit settings, but I am not even close.

 

I am sending "command1" and "command2" to the MAX3100 and I am reading out "commandIn1" and "commandIn2":

I will attach the two programs on this posting.  Anything anyone can do to help me get past this challenge would be great.

 

Thanks a lot in advance.
