Hi

Anybody working with an MPLAB ICE system, have you ever had the following
happen?

environment:    standard breadboard with switchmode psu (5.1v) working on an
lcd project
pic simulated:  16f873 (16xko module)


And this is what's happening

1.Waveforms output on let's say portb viewed with a scope, the duty cycles
are perfectly seperated, but the horisontal lines are rippled really badly.
2.In other instances a pin should be kept at 5v or 0v, but it just floats
around with a very noise 2v p-p random noise wave.
3.Even the 5v line from the pod is full of noise.

This is so bad not even my lcd project wants to work properly and it just
draws black boxes and 1's on the first line. I thought I could have a power
problem and my AC power is at around 227v-230V moving around there. But my
worst fear is my ICE system being stuffed because I don't understand these
random waves being present at pins I expected to be constant at 0 or 1 . I
would expect the power supply of the ICE to be stable. But if the ICE is
damaged, how can I properly be sure, and even worse, what could have
happened to cause this, I didn't put terrible voltages on it at all. It was
working fine this morning and then I did some button inputs on porta, and
since then --- this noise all over the signals.

Anybody have a suggestion?
