 Is the functions defined in CyUSB.dll the same with cyapi.lib?


Why I ask this question, because I want to realize functions like FMCFx3RefDesign in VBA, but I find the library used in this tool is static lib. The static cyapi.lib can't be used in VBA, so I think if I can use CyUSB.dll in VBA to realize read and write function as FMCFx3RefDesign. 


Any advice will be appreciated.

Yes, the functions you see in cyapi.lib and cyusb.dll are similar and have the same functionality.

You can use the dll to realize the same functionality as FMCFx3RefDesign.
