USB Controller on Spartan 3A 3400

hi,

    I am a newbie in FPGAz, so please dont mind my question.

>

    I am using Spartan 3A 3400 board which has a Cypress CY7C67300 USB controller on it. I am using XPS 10.1.03 .

>

  1. I want to know that if i want to use usb port for the output , will I need a USB IP core from IP catalog i.e (USB 2.0 Device) to connect this IC with microblaze   or    i have to develop some controller myself ? and how?

>

2.  Please tell me if there is some reference design related to this?

Re: USB Controller on Spartan 3A 3400

Hi,

 

There is a reference system which connects to Cypress USB controller chip on ML505.

 

This is connected using XPS_EPC and not XPS_USB2 core.

 

 ml505_bsb_std_ip_usb.zip

Thnx

Re: USB Controller on Spartan 3A 3400

Thanx for the help ,

         that example is for connecting keyboard to the FPGA , but still i didn't found any example where USB port is utilized for outputting the data.

        Please tell me if i want to use the example of usb for outputting the data, will i only have to create my own user application using the API documentation of XPS_EPC core  and add it in softwares in application tab ??

   OR

      I have to do something else?

                                                                                                            please help!!

You might wish to read up on how USB actually works.

You need to define a device class for your design. The device class then determines how data are formatted for transfer over the bus. Further, you may need a host device driver if your operating system doesn't have one for the chosen device class.

----------------------------Yes, I do this for a living.
