Hi All
this is related to an old reply i had from steve_in_nevada about the
buffer.txt info in the files section.
i have tried to use the BS2 to configure the PIC18F252 as a serial
FIFO buffer but i am running into difficulties as i constantly get the
DEBUG "Incorrect device ID, quitting" but i cant see what i'm doing
wrong. what does this actually mean and can you tell me if there are
any silly things that are easily overlooked.
i believed i have followed the instructions properly but obviously
there is something i missed
please help
steve

'identify' string being returned from the
18F252 is incorrect. What string IS being
returned?
This can happen because you don't have the
18F252 wired correctly, it's not running,
or you don't have an 18F252 chip.

Sorry to hear this is giving you problems. The purpose of the
device ID test is twofold. First, it verifies that communication
exists between your Stamp and the PIC by performing a simple
exchange. Second, it ensures that only a PIC suitable for the
program code is the target.
The Stamp program should be displaying the returned device ID on the
debug screen. Please relate what is being reported.
If all else fails, if you send me your PIC I'll either program it and
send it back or or trade you another PIC with the buffer program
loaded.
