16F1827 Changed INC File by Microchip?

[Ioannis]

Thanks both for the replies.

OK, now I can confirm that I am not hallucinated. I was sure that my file compiled fine before.

Now as Phil confirmed that specific line is omitted from the new version of the MPLAB 8.91.

Henrik, I have removed the & _BORV_25 from my configuration and all are fine, as I am sure, not specifing it is the same as having the old _BORV_25.

Just was annoyed by this things Microchip is doing now and then.

Hi,
Yes, I'd assume (which is NEVER a good thing but I can't actually find it in the datasheet) that all CONFIG bits are zero by default so since the HI threshold requires the BORV bit to be zero simply not setting it would be the same as specifically clearing it. Personally I'd change my CONFIG to match the new name, ie BORV_HI instead of BORV_25.

I suspect Microchip found out that the thresholds may not have been as close to 1.9V and 2.5V to warrant having the voltage as part of the the constant names so they changed it to high and low instead. Or it might have caused users to assume (see, never a good a thing) that they could set the threshold to any arbitrary voltage by simply changing 19 to 33 or whatever - I don't know.

Anyway, glad you're back up and running. I'm currently playing with a 16F1825 for the first time, what a nice, cheap little chip it is.

/Henrik.

Just like other flash memory in the chip, the config bits are all 1's when the chip is erased.
By not putting a BORV option in the code, it defaults to 1.9V.

Just change it to _BORV_HI

OK, thanks alot.

I still don't like that kind of surprises without warning.

Anyway, yes these chips are great! And they work from 1.8 to 5.5 Volts! Incredible!

And a lots of peripherals. I love them.
