In the mean time I found something I think I did wrong. The RX line from the 233 to the sx48 has no pull up 10 K. As for the sx48 it is an input(serin) , don't you think I need to add it. All my other inputs have them. The output has no need of it (serout) and that one is working. Second I had an compile error that thier is no memory space left for declaring variables. I seached the manual but could not emediat find how many var thier can be in 1 sx48. I'm using Byte and word . Can you give me a amount?. thanks Stef ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=193796#m193875 Need assistance?
