Can you post a schematic and perhaps a picture of your setup? It sounds like the SX28 is supposed to be a slave device. What device is the master and what are you trying to send to it. How are they connected? Are you trying to send data to a pin configured as a output instead of an input? ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=435619#m435624 Need assistance?
