PSoC black magic

[nathanww]

So, today the programming team took a braek from actually programming in order to design our control board. This included an in-depth test of the Cypress PSoC device, which exhibited some strage behavior.

The default configured analog inputs on the PSoC, when not connected to anything, seemed to be showing us data like an accelerometer would if mounted with its axis perpendicular to the board. In other words, the voltage that the Classmate reads varies depending on the number of Gs the board is experiencing.

When a jumper is placed along the analog input, it stops showing accelerometer data and jumps up. However, any analog input with a higher number than it also shows the same value. In other words, any analog inputs with a higher number behave as if they were reading from the same input.

The PSoC does this both when it is in "compatible" mode and "advanced" mode. Does anyone know what's going on, or how to fix it? I'm hoping we don't have to have it replaced/exorcised.
