Honored Contributoraccess to usb device in serial way
I want to connect FPGA to PC with usb device, but most applications access devices by serial (COM port). Is that possible let usb device appear as an additional COM port? Thanks!

Honored Contributor --- Quote Start --- But I would like to know if I don't have USB-to-serial adapter cable, are there other ways to convert it in software ? sorry I am beginner in FPGA. --- Quote End --- Why don't you start by telling me what type of FPGA board you have. Most FPGA boards have a JTAG connector that you can use to program them with. If you have a sufficiently recent FPGA, then you can also use JTAG to communicate with logic inside the design. You can learn about that method here http://www.alterawiki.com/wiki/using_the_usb-blaster_as_an_sopc/qsys_avalon-mm_master_tutorial Cheers, Dave
