I don't have the SX Tool Kit yet, So please don't think that I'm trying to get someone to solve a problem for me, but could someone please attach a snippet of assembly code that blinks a LED twice a second?

    What clock speed will you run the SX at?





    <SNIP>

    bugg

    setb ra.0··· ;make pin ra.0 high

    call delay

    clrb· ra.0··· ;make ra.0 low

    call delay

    jmp bugg··· ;do it again

    at www.sxlist.com there is a cool delay code generator. You enter the clock frequency, delay amount and it spits out the code as shown below.

    http://www.sxlist.com/cgi-bin/delay.exe

    The 5 uS delay shown below is running the SX at 4MHz

    del_5uS
    ·jmp·$+1
    ·jmp·$+1
    ·jmp·$+1
    ·jmp·$+1
    ·nop
    ·nop
    ·ret

    If you DO get an SX-Tech kit then you get the SX/B compiler at no charge and you can write your programs in BASIC -- SX/B is very close to PBASIC so what you've been doing with BASIC Stamps will be helpful.

    Bugg, you can download the SX-key software and compile SX/B programs and look at the source code generated, without having the SX-Key.

    Jon- could you please post a part#, I couldn't find where it says that you get the SX/B free. I'm looking at the SX Tool Tech kit PLUS.

    Go to our downloads section and get the SX-Key software -- it's part of that package.
