Wow, this is a large program listing and it is all jumbled together. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/blink.gif I tried looking at the code you are writing, however, I couldn&#39;t find anything too obvious.  

 

Can you provide us with what comes on the line just before line# 32 in the code display? This would help to zero in on the problem. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wink.gif  

 

Tnx.

No line number in your codes, So I cannot find which line is missing ";" or something else.

You could try removing the ";" from you# define statements e.g. 

# define ccomm 0x00# define cdata 0x01 

 

Hope this helps

You HAVe to remove the ";" from your defines. I had the same problem and got almost mad, until i found a "," after define. 

After a# never use a semicolon.
