hamster Posted December 20, 2012 Report Share Posted December 20, 2012 I'm thinking of implementing the V-USB stack on an FPGA. It is only USB 1.0, so OK for joysticks and keyboard emulation. If it can fit into an Arduino, how hard can it be to implement in an FPGA eh? I am hoping to get it to the point where it can be used for implementing MAME controllers or flightsim add-ons, but no further...Mike Link to comment Share on other sites More sharing options...

jbb Posted December 21, 2012 Report Share Posted December 21, 2012 Sounds good!Is it possible for FPGAs to self-program in some way?Just wondering if it would be possible to use this to program an fpga so it didn't need an external microcontroller or usb chip or JTAG programmer... I guess it would be possible to use it to program SPI flash containing a fpga program at least. Link to comment Share on other sites More sharing options...
Jack Gassett Posted December 21, 2012 Report Share Posted December 21, 2012 The Spartan 6 has a multi-boot feature that could be used in this manner. Link to comment Share on other sites More sharing options...
alvieboy Posted December 22, 2012 Report Share Posted December 22, 2012 hamster: but you plan do write an "hardware" version of it, right ?Alvie Link to comment Share on other sites More sharing options...
dpavlin Posted July 24, 2013 Report Share Posted July 24, 2013 Any progress on this topic? There is something similar for XESS board at http://www.xess.com/projects/FPGA-USB-V2/readmeusb-v2.php VHDL seems understandable to my newbie eyes, and I plan to try making primitive USB switcher out of it. It includes SDRAM, but as far as I can see it's not used anywhere so it should be applicable to all Papilios (since XESS is Spartan 3). Link to comment Share on other sites More sharing options...
