| 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 |
