i have seen your profile
01/01/70 00:00
It seems to have changed

Erik by god it is recently changed!
01/01/70 00:00
I think Neil is asking
01/01/70 00:00
Isn't this a 'C' problem rather than a RAM problem
01/01/70 00:00
Really?
01/01/70 00:00
code tested at simulator
01/01/70 00:00
So it's a hardware fault
01/01/70 00:00
Hardware tested
01/01/70 00:00
answer to "why":
01/01/70 00:00
but dont forget to put pull ups its port 0!
01/01/70 00:00
for the test - yes, sure, sorry, I forgot
01/01/70 00:00
"Hardware tested" and who gives a hoot
01/01/70 00:00
Tested?!
01/01/70 00:00
it's the HW then
01/01/70 00:00
Yes, it looks like that.
01/01/70 00:00
Oh no it doesn't!
01/01/70 00:00

01/01/70 00:00
