USB superspeed peripherals Forum Discussions

Hi,

I downloaded the latest version 1.2.1 of FX3 SDK, and started usning.

When I click on "New" or on "Cypress provided Interfaces", it is getting hanged.

Is there any supporting software required for GPIF programmer?

There is no EZ-USB 3.0 Examples of HID interfacesin super speed?

Where I can find this Examples?

Hi,

I'm design a bridge to read/write 8080 type device through USB. But I have problem on the GPIF2 waveform design. For write operation, I can use DMA_RDY_CT to trigger write operation. But how to trigger read operation?

A sample project that uses GPIF2 as master to interface with a SRAM type device would be much appreciated.

Thanks!

Hello guys,

I am a beginner in working with Eclipse.

Can someone tell me how can I generate an elf file or .img file in sdk

Hello guys,

Can some one send me the slave fifo 2 bit address sample application from cypress. I have changed mine completely so can some one attach me this application.

now I'm looking at the connection between pc and usb3.0 .In the usb control center ,  Data Transfers  connect to usb3.0 by which functions ? if possible , can you tell me all functions when it  transfers ?

While implementing  a Windows 7 application to read data from IN endpoints I started by following closely “the letter of the law” and looped the CyAPI XferData call to the driver with a buffer length and length according to the documentation namely 512 bytes for high speed and 1024 for super speed. This resulted in very poor performance, as I was missing data. Next I decided to see if I used for the aforementioned call bigger buffer length, which immediately improved performance. However, the upper limit I hit was 32K size buffers, which is really good but for the fact that I still miss some data in between XferData calls. I would appreciate anybody on the forum that may have a solution for me, even if it means making changes to the device driver to handle much bigger buffer transfers.

I check most of example code know GPIF can input a clock as reference. Does GPIF have a PLL(phase lock loop) let user can program and output to other device as a reference clock?

Thanks.

Hi All,

I want FX3 generate digital video signal as video pattern generator. The signal I needed are pixel clock, horizontal reference(h-ref, someone says (data enable)DE signal), vertical sync(v-sync), and data. 

For example. we can see the signal like as application note AN75779 "Interfacing an Image Sensor to EZ-USB® FX3™ in a USB video class (UVC) Framework"  Figure2

In actually I want generate signal include "FV" , "LV" , "PCLK" , "DATA" whole signal in Figure2.  Does GPIF2 designer can support this type signal?

Thanks.

Anytime I call "CyU3PUsbGetDevProperty(CY_U3P_USB_PROP_FRAMECNT,&Frame);" I get "CY_U3P_ERROR_BAD_ARGUMENT" returned. I am succesfully firing a USB event callback on each SOF and I then need to detect the '0' frames whilst still in the event callback. I am using 1.2.3 libraries. How do I make this work?
