Another problem...
The BS2_TO_SX.BS2 and SX_TO_BS2.SXB programs don't seem to work for me.

 

I connected the pins according to the programs, linked the two grounds together and didn't alter anything except the SX's clock...

Here's a sample of my result:



[code]
Out: N    In: &lt;?&gt;
Out: O    In: &lt;?&gt;
Out: P    In: 8
Out: Q    In: 8
Out: R    In: &lt;
Out: S    In: &lt;
Out: T    In: &lt;
Out: U    In: &lt;
Out: V    In: &lt;
Out: W    In: 8
Out: X    In: &lt;
Out: Y    In: 8
Out: Z    In: &lt;
Out: A    In: &lt;?&gt;
Out: B    In: &lt;?&gt;
Out: C    In: &lt;?&gt;
Out: D    In: &lt;?&gt; 
[/code]

I did alter the clock of the SX, if that makes a difference. I don't have a 20mhz resonator (Just the 4mhz and 50mhz that come with the tech toolkit) so I set it to 50mhz with no improved response, then set it to 4mhz with the same result.

I understand I can simulate a 20mhz clock with the SX-key but that would make it impossible for me to read the debug screen on the BS2 side (I've only got one com port).

I have a request for your book... can you please go into detail about resonators and crystals and the like? There's next to no information out there explaining such things to a total newbie of microprocessors. I'm still extremely vague on many issues related to them after studying every single source parallax provides. It seems that most of the material just simply assumes you know how they work, or that your going to use the internal RC clock.

I'm sorry for being such a trouble with all this. I really am attempting to learn all this on my own without bugging you... I use this forum as an absolute last resort and as a result spend a lot of time re-reading things I've already read, and experimenting for hours with nothing to show for it.

I'm not trying to be an annoying newbie... I'm just born that way I guess.
