Sensitivity of Cypress board

[SteveD]

I recently wired a cypress board to a single switch. I have good communications and everything, however the board seems to be really sensitive. If i am holding the board, all of the inputs will constantly flash on-off. On the switch that i wired, when i switch off, the light stays off on the digital display. but when i turn it on, it will constantly flash. Is this normal. I assume its just due to my poor wiring job. Anything to reduce this sensitivity, other than rewiring with solid core wires?

If you are using the extended mode, you may need to enable a pull up or pull down on the digital inputs. Each digital input can be configured to default to high, default to low, or default to nothing (aka flashy/jittery).

PS: I think this set-able pull up/down is the coolest thing since capacitive touch sensors and sliced bread.
