I have not heard of anyone needing more than one accelerometer, but I am assuming you are talking about a standard 3-axis chip.
If you want to use more than one 3-axis chip, then I am very curious about your application/idea.
Conceptually, all you need is enough A/D ports on your PSOC to do the basic interface. As I recall, there are at least twelve on the board, so you should be able to make it work.
Thank you for your answer. In this case, I want to show in PC about 8 direction movement (like direction of the wind, e.g: N, NE, E, SE, S, SW, W, NW) using two accelerometer
I can't see why you'd need two accelerometers for that... Please look into 2- or 3-axis accelerometers, they can give you 2-axis information in a single package!
