What OSC are you running the PIC at?
Look at the electrical specifications in the PICs data sheet to see what speeds work with different voltages.

Hi,
Which inputs do you use for Xbee ???

************************************************** ***********************
Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...
************************************************** ***********************
IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

It looks like the 16F88 needs a minimum of 4V to operate. The 16LF88 needs only 2V. Try the LF part, use 3.3V for both and turn off Brownout Detect.

for this project, i have "DEFINE OSC 8"
>>Look at the electrical specifications in the PICs data sheet to see what speeds work with different voltages.
i've missed something there, thx for the reminder

>Which inputs do you use for Xbee ???
pin 1 for 3.3Vcc
pin 3 for input from RB5(tx) from pic

actually i didn't see that in the datasheet i have but i'll look again. in the meantime i'll pick up some 16LF88's which are better suited to this particular prototype session.
thx

Bad way of asking the Question ... ( I think )

I think I didn't write it correctly ...
Which inputs of the PIC do you use for Xbee reading ...

no problem, i read backwards randomly at times, so maybe i mis-read the question.Originally Posted by Acetronics
i use pin RB2(rx) is the only reading from the xbee currently.

Hi,
RB2 is then a Schmitt trigger Input ... if used for RX ...
Can a 5v Powered schmitt Trigger input read 3v3 levels ??? ...
Good Question !!!

indeed, great question and prompts me to research more:
via p#11 of the datasheet from http://ww1.microchip.com/downloads/e...doc/30487c.pdf ...
i'm using pin RB2 as [I]nput and not using the buffer as a Schmitt trigger input. Pin RB2 as [I]nput is for ausart.
the Schmitt trigger input would be for serial programming ICD or low voltage ICSP programming but not on pin RB2, unless for SPI data out, which in my case it is not.
is that how you read it?
thx

on another board with a pic16f88 with RB2 reading from pin2 on the xbee sitting on a xbib-r-dev board, the data is read just fine. yes, RB2 can read 3.3v levels.
|
via the data sheet for the PIC16LF88-I/P on mouser's site i do now, see the pic16f88 listed at 4V.
thanks
