Hello,
I want to design FPGA-based PC oscilloscope controlled by a user of the PC. I am not sure how to provide communication between PC based application (a main program on PC; this will be written either in C or Visual Basic) and FPGA-board. A port for communication will be RS232 and I want to get my scope working under Windows XP. What you think, is writing a driver necessary for such system? (Unfortunately, I have no experience with writing drivers.)
