Have you heard of Arduino ? I am sure you would have come across Arduino atleast once. Let me briefly tell you about Arduino. It is a platform which is considered to be the easiest embedded platform to work with. Programming an Arduino is child's play. The Arduino community makes what is called Arduino shield which can sit on top of any Arduino board and provide additional functionality such as XBEE, WIFI, Ethernet and so on.

A team at Michigan State University has now put together a PSoC5 board which will work with Arduino shield. The overall goal of this project is to have PSoC 5 be “Arduino-friendly”. In other words, one of the team at MSU is trying to have Arduino users purchase PSoC products. The overall goal of this project is to have a design that will prevent any technical difficulty when interacting Arduino shields with PSoC 5.

 I have heard of arduino boards. but arduino shields are relatively new to me. By "PSoC friendly arduino shields" do mean that those boards which provide additional functionality for an arduino based platform are being enhanced to be compatible with a PSoC based platform also?

 sorry there was a mistake, wanted to ask "arduino friendly PSoC shield" meaning. instead reversed.  

Arduino shields are additional daughter boards that sit on the existing Arduino board to prpvide funtionality such Ethernet and XBEE interface. I believe that the university is trying to make PSoC5 boards on to which the Arduino shileds can fit and provide the added functionality. This was you do not need additoinal shileds for PSoC5. The already available Arduino shileds can fit int to the custom PSoC5 board.

oh nice.so its the PSoC boards that are enhanced to be compatible with an arduino shield.
