Ref Prog guide: MSP430 USB API Stack for CDC/PHDC/HID/MSC On page 150 it says "open the workspace file (".eww") " The MSP430 software "says" .ewp. Can i conclude .eww is wrong? Questions: How do I open a .ewp file? Do you have a doc that tells me how to incorporate MSP430 API into a Visual C++ 6.0 workspace? Please advise this hardware person. npappasz@gmail.com
