Subversion Repositories usbhostslave

USBHostSlave has been successfully compiled using Quartus 4.2

For some reason I have not been able to use SOPC Builder 4.2 to build the usb SOPC component

However, SOPC Builder 4.1 generates a usable SOPC component. This may be an error on my part, I need to

investigate further.

USBHostSlave has been tested in a SystemC simulation, and on a Altera Nios development kit Cyclone edition.

Release notes:

// Version 0.6 - Feb 4th 2005. Fixed bit stuffing and de-stuffing. This version succesfully supports

//             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.

// Version 1.0 - October 14th 2005. Seperated the bus clock from the usb logic clock

//               Modified RX and TX fifo status registers, and removed TX fifo data count

//               register. Added RESET_CORE bit to HOST_SLAVE_CONTROL_REG.

//               Fixed slave mode bug which caused receive fifo to

//               be filled with incoming data when the slave was

//               responding with a NAK, and the data should have been discarded.

//             TODO: Test isochronous mode, and low speed mode using uClinux driver

//                   Add frame period adjustment capability

//                   Add compilation flags for slave only and host only versions

//                   Create data bus width options beyond 8-bit
