Hi There Sailer;

If it's possible in SX/B to slow the SX down by many orders of magnitude, you might stick an LED on the SX transmit bit, rb.0, and observe what it is sending. You can make things slow (enough ??) by using the SX-Key as the clock source and setting its speed in the "clock" window, or in the program with a FREQ directive.

I'm not positive you can slow it down enough, but unless you have an oscilloscope, it's probably as good an indication as you can get.

Of course that does not help the Propeller end, but it might eliminate problems in half of the equipment.

Alternately use the SX-Key's "debug" facility and single step the compiled assembly equivalent program to see what it's up to.

Have you tried Guenther's simulator ?

Really, this task is not THAT tough!  I'll write you a variable speed assembly routine (not much good at SX/B yet) to output data from the SX if you wish.

I presume you do have an SX-Key ??  You're dead without one !

Cheers,

Peter (pjv)
