Thanks Good that the semiconductor Manufacturers
published the Algorithms
to write to their RAMs ... :-)
Be careful... I've come across ICs where the full data sheet, needed to
use the part in a normal circuit (and not, for example to program it
before using it) is covered by an NDA.
Sorry, but the above is Nonsense in my eyes.
And in mine.
If they publish the datasheets, thy could inform
companies that produced
the programmers anyways to reach the end users.
Ther isn't any benefit when they hold the algorithms secret.
If the hold the algorithm,s secret and soemthing doesn;t work (even if
you are usign an apporved programmer) then you have no way of knowing
what the problem is. And I am certain;y not happy with that.
Surely the thing to do is to publsijh the inforamtion but make it clear
it's not supported and that the IC is only gauranteed if you use the
apporved programmer, If you build a porgrammer you're on your own.
OK, some people will try to cheat. If it's a hbbyist with 1 or 2 ICs, the
simplest thing is to replace them -- the first time. It's peanuts to the
company to do that. The second time you start asking questions as to why
he's so unlucky wen nobody else has problems. If it's a company that's
progerammed afew thosand parts and is having problems, you send somebody
round to demonstrate what htey are doing. And if they're not using an
approved programmer, that;'s the end of it.
