Andy, thanks. My rep says the samples should be here soon but no
idea on what rev... I'll ask Carl to send the B024 update. Did you
have any problems with the 16F8xx and B024 firmware other than EEPROM?
The reason I've held back on both the samples and the firmware update
is that I need to move some 16C77 code to the 16F877 and it's 12-Bit
A/Ds for use in a DAQ system and I want to store calibration data in
EEPROM. It looks like I'll have plenty of time for my garden until I
get my `paws' on updated silicon...

   BTW, have you used the 16F877's 12-Bit A/D? I'm replacing an existing
design that used an external 12-Bit A/D and a precision 4.096V reference
with a pot to provide a 1mv resolution. I'm tempted to go back to a MAX186
A/D with it's internal reference and the data book `reference adjust'
circuit. I used that in my weather station several years ago and it's been
very accurate. That's my concern with the 16F877. Given a precision
reference, I wonder if I can get a similar accuracy. However, it would be
nice to eliminate the pot, external A/D, and allow the user to enter
calibration data to EEPROM.
