Thanks to one of our friends from new Zealand ... we can recover the OscTune Value !!!


This is for 12F675, but can be translated for other ... Flash memory devices ...

Hi, Sayzer

Interesting - really !

and Which is your programmer ??? How does it do that ???

mmm, interesting link but, sorry Alain, to me wasting my time (based on >50$/Hour) for a <2$ device is a real money waste... even with the recent things that happened...

If you lost your OSC calibration it might mean that you overlooked your PIC programmer options.. or simply it's a freeware. With any of the previous, the first sentence apply. BTW, if you don't need anything timing critical, even with a stupid RC osc, just don't recall it and it will work.

Ya know ...,

I think the first post was a perfectly valid way of regaining an OSCCAL value if it got overwritten or erased.

What's the Beef? :eek:

The one I use is local made.

I don not think you can find it in France, but if you like to import and trade, I can help you out.

Hi, Sayzer

If I try to understand Turkish ... I see "read","Ok","cancel" and "help" commands ( think to correct me if I'm wrong ... )

so, With that programmer, seems You could only read or modify the cal value ...

but, if overwritten ( by error ! ) ... you can't recover the initial value.

My Picstart also does read/modify ...

but I don't know any programmer in this small world able to recover a LOST value. ... would yours automatically retrieve that value ???


PS: By the way ... does " Oku " mean you got it wrong ???

- 27th November 2007, 18:11
Finally, I got it !!!

no Turkish product at all ... booooo !!!


and the "Microburn" program doesn't show any kind of auto-retrieving for the cal value ...

Program also FREELY available in English ...
