Very nice for third countries but... | | 01/01/70 00:00 |
My Advice | | 01/01/70 00:00 |
Today's top award for Stating The Blindingly Obvious... | | 01/01/70 00:00 |
Doesn't make sense | | 01/01/70 00:00 |
A microcontroller is a nice logic-chip tester | | 01/01/70 00:00 |
device in question is not for identifying unknown chips | | 01/01/70 00:00 |
Wasn't talking about linked device | | 01/01/70 00:00 |
IC logic still popular here(used) | | 01/01/70 00:00 |
sure, but | | 01/01/70 00:00 |
sure, but, but | | 01/01/70 00:00 |
sure, but, but, but | | 01/01/70 00:00 |
Limitations | | 01/01/70 00:00 |
Areas of Doubt and Uncertainty | | 01/01/70 00:00 |
I can imagine one case | | 01/01/70 00:00 |
That would have different pinout | | 01/01/70 00:00 |
what is all this about identifying chips | | 01/01/70 00:00 |
See Richard's post | | 01/01/70 00:00 |
Brute Force - The IC pins would curl up before finish | | 01/01/70 00:00 |
Actually not too ahrd/expensive to detect chips | | 01/01/70 00:00 |
But | | 01/01/70 00:00 |
Of course | | 01/01/70 00:00 |
Again, it depends on your goals | | 01/01/70 00:00 |
Scope of project is important | | 01/01/70 00:00 |
It's more interesting | | 01/01/70 00:00 |
both of my old portable programmers do this | | 01/01/70 00:00 |
Is there codes? | | 01/01/70 00:00 |
What, exactly, are you looking for? | | 01/01/70 00:00 |
unknown is hard....known is easy? | | 01/01/70 00:00 |
it's possible, but not reliable to check for unknowns | | 01/01/70 00:00 |
xeltex superpro | | 01/01/70 00:00 |
be careful ... that was several revisions ago ... | | 01/01/70 00:00 |
RE: known IC logic for test is easy? | | 01/01/70 00:00 |
unknown.... | | 01/01/70 00:00 |
Pardon?? | | 01/01/70 00:00 |
IF you can't recognize the part, THEN discard it! | | 01/01/70 00:00 |
The most likely reason you'd want to do that ... | | 01/01/70 00:00 |
The code was compiled and in a library | | 01/01/70 00:00 |
Place..The code was compiled and in a library | | 01/01/70 00:00 |
Will that help? | | 01/01/70 00:00 |
in the future... | | 01/01/70 00:00 |
It's just a small-C compiler with intrinsics for SuperPro | | 01/01/70 00:00 |
help?? | | 01/01/70 00:00 |
Can't you just go from first principles? | | 01/01/70 00:00 |
If you want that software, you should contact XELTEK | | 01/01/70 00:00 |
The code was compiled and in a library??? | | 01/01/70 00:00 |
Well, obvisouly! | | 01/01/70 00:00 |
The hardware for this sort of thing is not rocket science | | 01/01/70 00:00 |
library binary | | 01/01/70 00:00 |
I can't purchase the expensive SuperPro | | 01/01/70 00:00 |
homemade | | 01/01/70 00:00 |
this makes no sense | | 01/01/70 00:00 |
missing?? | | 01/01/70 00:00 |
no, I am not | | 01/01/70 00:00 |
not so fast ... | | 01/01/70 00:00 |
while all that is valid - to an extent | | 01/01/70 00:00 |
kitchen table... | | 01/01/70 00:00 |
Kitchen-table = home built with lacking tools/knowledge | | 01/01/70 00:00 |
understand.... | | 01/01/70 00:00 |
Can often be solder problems | | 01/01/70 00:00 |
multiply | | 01/01/70 00:00 |
if you use that many .... | | 01/01/70 00:00 |
work's | | 01/01/70 00:00 |
because | | 01/01/70 00:00 |
You're right in large part, but ... | | 01/01/70 00:00 |
did NOT bring this up for any other reason | | 01/01/70 00:00 |
back... | | 01/01/70 00:00 |
Can have uC or PC as master - just different advantages | | 01/01/70 00:00 |
You'll need lots of storage. | | 01/01/70 00:00 |
For what? | | 01/01/70 00:00 |
You need storage for the 250K test vector sets | | 01/01/70 00:00 |
Yes, you have to do the work | | 01/01/70 00:00 |
"works (sic) flawlessly (sic)" | | 01/01/70 00:00 |
You haven't the means to determine that it works flawlessly | | 01/01/70 00:00 |
XOR normally easier than trying high-end drive + sampling | | 01/01/70 00:00 |
That does work if you have one functional part for "seed" | | 01/01/70 00:00 |
Can perform time calibrations without specific seed | | 01/01/70 00:00 |
None of this works with just an XOR | | 01/01/70 00:00 |
Just an XOR? | | 01/01/70 00:00 |
These assertions look entirely wrong to me. | | 01/01/70 00:00 |
Read up on phase detectors and separate from lgic detect | | 01/01/70 00:00 |
Yes, I know about phase detectors, and in this case... | | 01/01/70 00:00 |
Learn, and it will not be irrelevant anymoer | | 01/01/70 00:00 |
This stuff is still irrelevant until you know the type | | 01/01/70 00:00 |
And the type covered again and again | | 01/01/70 00:00 |
For the purposes described by the O/P it's not relevant | | 01/01/70 00:00 |
Already covered | | 01/01/70 00:00 |
Until you have a way of ascertaining the ins and outs ... | | 01/01/70 00:00 |
Obvious, but _you_ singled out propagation delay | | 01/01/70 00:00 |
various but still MCS-51 | | 01/01/70 00:00 |
Difference hobby or commercial use | | 01/01/70 00:00 |
you caught a VERY important issue - and did not know | | 01/01/70 00:00 |
avoid kicthen table | | 01/01/70 00:00 |
there is no way in hades .... | | 01/01/70 00:00 |
Not even commercial testers are really commercial grade | | 01/01/70 00:00 |
emphasizing the above good post | | 01/01/70 00:00 |
I'd guess the application is a bit different | | 01/01/70 00:00 |
ah ... | | 01/01/70 00:00 |
Yes ... | | 01/01/70 00:00 |
It's always a tradeoff between time and money | | 01/01/70 00:00 |
e-bay?? | | 01/01/70 00:00 |
If you find one and buy it ... | | 01/01/70 00:00 |
If you REALLY want one of these ... but one that works ... | | 01/01/70 00:00 |
not a defective chip, but ... | | 01/01/70 00:00 |
