ATMega 64 Problems - diggins1980 - Jan 20 12:00:00 2004
Hi there
Any help with this matter would be greatly appreciated. I have a
CMOS camera VV6301 interfaced with an ATmega 64 on portf. JTAG Has
been disabled and the port configured as an input port.
When I try to read data off the port with the camera connected /
disconnected I appear to get spurious logic levels. I have tried
enabling the internal pull ups but had the same problem.
With the camera removed from the system and random logic levels
applied to the port only data changes would be apparent if a pin was
taken to ground. No changes were apparent with VCC.
Have I overlooked something here or do I have a port failure.
Many Thanks for any help given.
Regards
Simon Dinsmore

I have some working functions for the DS1307, suppose
it is not too different from the DS1302. Mail me if
you want a copy. --- Emerson Santos <emersonsantosrj@emer...> wrote:
