For those who wish to use a pre-configured Quartus project, I have included two files;
|
|
usbhostslaveQuartusProj.qar - Quartus project archive
|
|
usbHostSlaveNiosIDEProj.zip - NIOS IDE project zip file. You can use NIOS IDE File>>import to open the file
|
|
|
|
|
|
If you wish to replicate the hardware setup, then you will need to replace
|
|
the standard 50MHz oscillator with a 48MHz oscillator (Digikey XC280-ND),
|
|
and you will need a add a Santa Cruz daughter card with two USB transceivers.
|
|
|
|
If there is enough interest, I will consider producing a Santa Cruz daughter card
|
|
with the hardware required to support this core.
|
|
Please email me at sfielding@base2designs.com if you are interested in this option.

// Version 0.6 - Feb 4th 2005. Fixed bit stuffing and de-stuffing. This version succesfully supports
|
control reads and writes to USB flash dongle
|
// control reads and writes to USB flash dongle
|
|
// Version 0.7 - Feb 24th 2005. Added support for isochronous transfers, fixed resume, connect and disconnect
|
|
// time outs, added low speed EOP keep alive. The TX bit rate is now controlled by
|
|
// SIETransmitter, and takes account of the requirement that SOF, and PREAMBLE are always full
|
|
// speed, and TX resume is always low speed.
|
|
// Fixed read clock recovery (readUSBWireData.v) issue which was resulting
|
|
// in missing receive packets.
|
|
// Fixed broken SOF Sync mode (where transacations are synchronized with the SOF transmission)
|
|
// by adding kludged delay to softranmit. This needs to be fixed properly.
|
|
// This version has undergone limited testing
|
|
// with full speed flash dongle, low speed keyboard, and a PC in full and low speed modes.
|
|
// Version 0.8 - June 24th 2005. Added bus access to the host SOFTimer. This version has been tested
|
|
// with uClinux, and is known to work with a full speed USB flash stick.
|
|
// Moving Opencores project status from Beta to done.
|
|
// TODO: Test isochronous mode, and low speed mode using uClinux driver
|
|
// Create a seperate clock domain for the bus interface
|
|
// Add frame period adjustment capability
|
|
// Add compilation flags for slave only and host only versions
|
|
// Create data bus width options beyond 8-bit
