I have just gotten the sx tool kit and have begun to learn the chip. But I cannot seem to download a sample programm and run it. Every time I try to run the program it says, "SX Key not found on com1".

    Do you have and SX-Key or SX-Blitz? If the latter, you can only download a program to the SX, you can't run it. After downloading, remove power, remove the Blitz, plug in a resonator, then restore power.

    John,

    It is the SX key, but I found my problem. The power supply was only putting out 4 volts. I threw in another and it runs the sample program fine.

    However, I was under the impression that you could write in PBasic and compile to the sx. Is that true? Learning a whole new language will be a task.

    You cannot compile PBASIC to run on the SX, you'll write the program in SX/B. Don't worry, the switch from PBASIC to SX/B is not terribly dramatic and the horsepower gained is worth the small effort. I haven't written a PBASIC program for myself in ages; everything I've done the last 18 months has been on the SX, using SX/B and occasionally tossing in some Assembly when that makes sense to do.

    John,

    Again I spoke too soon. I got the books, "programming the SX Microcontroller" and "SX Key developement System manual" and in neither could I find anything about SX/B program set.

    Then I found an article called, "Practical SX/B" written by Jon Williams. It shows how to program in SX/B and it appears as straight forward as you said.

    Many thanks,

    Jon,

    This Lou of CT. If you remember my last name, you will know why I was called chick all my life.

    Call me when you get a chance.
