| Abstract: | For many digital product need an arbitrary sequence digital signal source when they are developing and debugging,a simple 16 bit digital signal source based on USB technology is designed and implemented.The arbitrary sequence is created by PC and are trans-mitted through USB interface.System hardware receive USB data and complete serial to parallel conversion.Finally,digital sequence is gotten,which could used as debug source.The design and implementation method is illustrated in hardware,firmware,device dr... |
