If I make sychronous converter to asyncronous converter before the Databoy with the correct timing and Ram storage with right crystal clock and then send the information (data) to the Databoy scope as asyncronous signal why could I not read that signal as data on asynchronous datascope?
Yes you can do that but you would need to do it with a convertor in a CPLD because its not an off the shelf type application.That is not clear is what form the syncronous data takes is it i2c or USB because you mention both of these,are you trying to make a USB logic analyser out of a datascope? If you are then again it could be done but you need to use some custom logic to do that.
