Hello

I find UART on S1-Port in FX3S but I can't find how to configure S1-port.

Could you tell me some advice?? I use custom board based on FS3S EVM. Only way to Communicate UART is S1 Port.

Regards

Hi,

I am building an application that would transfer data via SPI to a device connected on SPI. To start, I am trying to transfer data between host and CX3. I am using CyU3PDebugPrint to print data from CX3 to the hyperterminal. Is there a way I can transfer data from hypterterminal to CX3? 

Also, I have to build the host application from scratch to talk to SPI slave. Are there any docs/tutorials that will be useful?

Thanks.

How do I integrate the GPIF II Designer app into EZ-USB-Suite under Windows: there is a button (and menu item) for it in the IDE, but it's grey-ed out.

In preferences, there is a way to supply the GPIF II Designer path, but that appears to only be for Linux/MAC (apparently when the designer runs on a virtual machine).

Dear sir,
we are working with FX3 board.In that we use c# for application with CYusb.dll library.
we always get the device as NULL when using “CyUSBDevice MyDevice = usbDevices[0] as CyUSBDevice,If we not create single other endpoint (interrupt or bulk or iso).
we always get the device as not NULL(device is detected ) when using “CyUSBDevice MyDevice = usbDevices[0] as CyUSBDevice,If we  create other one endpoint(interrupt or bulk or iso).
we want to access the device with out creating the other endpoints(interrupt or bulk or iso),is it possible or not.we want to transfer data only with controle endpoint.
please give your suggestion

After rebooting a PC, I can't get a device count. 

But I can see the device name at windows device manager.

How can I prevent this problem? 

I've read through AN65974 regarding the Synchronous Slave FIFO mode, and the associated FPGA example design.  It seems like the examples cover the GPIF cases where there is a full DMA buffer transfer, then a partial or zero-length transfer.  What about the case where the host is sending a partial packet to the FX3, like 128 bytes?  Is it possible to notify the FPGA there is data to be read from the FX3?  It seems like FlagC does not go high until the DMA buffer is completely full?  Is that correct?

Thanks,

 I found that when I downloaded a new firmware to RAM by control center, there will be a vendor request 0xA0 sent to the firmware. If I process the request and return handled flag as true, the new device is recognized in control center with a delay of about 3s. But if I do not handle this request, the new device will be recognized immediately. Why?

Thanks,

I have the CY4701 GX3 reference design kit.  After downloading and installing the drivers it appears to work with USB 3.0 ports only.  When plugged into a USB 2.0 port it doesn't power up at all.  Is this supposed to work on a USB 2.0 port?

Thanks,

Mike

Dear Sir,

The FX3 support 32 bit GPIF II interface.we are using GPIF Designer 1.0 to Draw interface and state machine diagram.in interface there are only 8,16,24,32 selection for GPIF data bus width.but i need 12 GPIF data bus.please help for selection 12 Bit GPIF data bus.

Thanking you

Hi, is there a Streamer application for Linux available like the one that is provided for Windows with the SDK 1.3 to test continuous throughput ? Any help as highly appreciated!
