hello,

I am trying to write a program for the game boy camera chip,
there are several web sites that explain how to do this, but
I need remedial help

If any of you can help to decipher the data sheet for the
image processor chip, I would be greatly appreciative.

html site with the datasheet

I've never tried to communicate with a chip like this and I'm
stuck.

I'm doing this with a stamp for the time being, and I'm pretty
much confused between the description of how it describes how to
do a reset, for example, and between what the timing diagrams show
that you need to do.

for example in the reset, the data sheet tells you that 'the reset
sequence completes when both the Xrst and RESET signals are set low.'

This seems to be saying that you hold both of these signals low, and
this will reset the chip.

However, the timing diagram shows the Xrst and RESET signals as
begining high, then going low, with the clock (Xck) signal pulsing
above, then the Xrst and RESET resuming high again.

So, in other words it shows that the Xrst And RESET signals just need
to be pulsed low, to get a reset.

Which is it?  Am I getting wound up over the way this thing is worded?  Do
you most usually 'pulse' these type of signals?  And I'm not sure if
you have to send a pulse to the RESET pins while you clock the clock.

Any help is greatly appreciated.  Eventually, after I try everything each
possible way, I'll get this thing to work.  But your help would speed
me along.


thanks in advance
