Ok... I think your getting pretty frustrated with me so I'll just make this as brief as possible...

I have been understanding how HFC works since about 5 minutes after you originally mentioned it. In fact, I had used something of a crude, inverted, form in my

original program I posted without even realizing it. My questions weren't related to how it works, more to the exact problems I was having with my applications of it.

I know I did something wrong... I was asking what.

 

I did verify several times that I had the connections correct... I will go into deftail now (and verify again as I do so):
BS2 Pin 15 (RTS) -----> SX pin RA.1 (CTS)
BS2 Pin 14 (TX) -------> SX pin RA.0 (RX)
BS2 Pin 13 (CTS) -----> SX pin RA.3 (RTS)
BS2 Pin 12 (RX) ------> SX pin RA.2 (TX)
LED -> 220ohm Resistor -> RC.7 (LED)
BS2 Vss -------> SX Vss
SX is powered by regulated 5.9volt wall-wart to barrel jack on SX Tech board
BS2 powered by 9volt battery

 

When I attempted to use the 50mhz resonator, I did have it changed to OSCHS2. I also changed the FREQ command accordingly.

 

When I said I didn't understand resonators, I meant more practical aspects... Are they polarized? How do you read the markings on them? Does static damage them?

Do magnetic fields damage them? Which is better, a crystal or a resonator? Can I underclock them to run at a slower speed(Use a lower FREQ?)? What speeds are best

for what applications? What is too fast for X? What is too slow for X? ect... I've answered some of those, but I just wanted to give an example of the information I

still wanted after reading and re-reading the sources you listed and many more.

 

I have directly downloaded your attached programs into my stamp and SX, I did not edit the programs at all except to change the clock of the SX, and I still get this

result:




[code]
Out: J    In: 8
Out: K    In: 8
Out: L    In: 8
Out: M    In: 8
Out: N    In: 8
Out: O    In: 8
Out: P    In: <?>
Out: Q    In: <?>
Out: R    In: <?>
Out: S    In: <?>
Out: T    In: <?>
Out: U    In: <?>
Out: V    In: <?>
Out: W    In: <?>
Out: X    In: 8
Out: Y    In: 8 
[/code]

 

I've attached both programs exactly as I ran them.

 

If its not in my wiring or your program, then it must be something else. I wish I knew what.

 

I'm sorry your frustrated with me. I will attempt to figure out things on my own from this point. Thank you for your help... I've learned a lot from you.
