how did you check the osc freq?
Hey Charles,
Nice work answering your own question;)
Would you please explain how you tested the osc freq? Could you share your test code?
I would like to learn more about this.
I usually base my projects around the following 3 PIC's, as they share the same basic pinout...
8pin - 12F683
14pin - 16F688
20pin - 16F690
I would like to learn how to set/test the osctune register. I would also like to know how to read a new chip to view the osctune register as set from the factory.
Thanks
Dwight
Now it's starting to make sense!!
Thanks Languer,
That helps alot!! So the fact is that the chips that I am using are actually later generation chips with the OSCTUNE (and better quality internal oscillators).
I do have the datasheets and did do a search for both OSCCAL and OSCTUNE. I obviously found the latter not the former. I did not realize that OSCTUNE and OSCCAL were not the same thing, just stated differently, now I do.
Quote:
Older chips or lower end chips (10Fs) have the OSCCAL reg. You would much prefer the OSCTUNE register to the OSCCAL one (if given the choice).
This one statement helps a bunch.
If there has been one thing I have had to learn over the past year or so is to always check the datasheets. Then come here for more experienced help.
Thanks to all for your assistance.

These PICS are like intricate puzzles just waiting for one to discover their secrets and MASTER their capabilities.
