USB low-full-high speed peripherals Forum Discussions

Hello,

with the USB-Serial Configuration Utility is possible to set some string descriptors(1):

.Manufacturer
.Product
.Serial Number

The cyusbserial API, however, doesn't contain any function to set these strings.

Manually set the device serial number is adequate only during the prototyping phase.
Once in production, we will need to automatically generate and set a serial number for each device.

Could you please tell me how to do it?

Best regards,

Hi All,

  which Cypress Development kit will have features  for USB MP3 player   ,FM RADIO and cap sense? 
 

Hi-

  I'm new to using the Cypress chips (FX2), and I'm looking for some pointers on getting started with CyUSB.net ...

  I have the FX2LP set up in FIFO mode, bulk endpoint (IN) on EP6, which is connected to an FPGA that generates packets to send.  This is based on the AN61345 slave FIFO app note, but modified so it puts a data packet in the FIFO every 0.5 ms.  I can read this data using the Streamer C# application (AN4053), or the Control Center.  I can make a simple C# program of my own that reads packets, based on these examples.

   To this point, I've usually used RS232 (or CDC device class), for which the process typically is:

1. open a handle to the port (CreateHandle)

2. this causes the operating system to buffer data until read by the application; also, it grants exclusive access

3. read data

4. close the port when done

5. if the operating system's buffer overflowed, an error flag is set that the program can see

   Using CyUSB.net...

1. Is there an equivalent of "opening the endpoint"?  I don't see an equivalent way to signal to CyUSB, "hey, direct all incoming packets to my application!"

2. How do I guarantee that I get all packets in order, with none lost?

3. How do I guarantee exclusive access for my program?

For example, I can run 2 instances of the Streamer example side-by-side, and neither knows that it is losing half the data to the other program!

Thanks!

Dear All,

    I refer to the design("AN61345 - Slave FIFO Interface using fpga"), and have been able to get the data, but this is not I want, the packet is too large; I hope to get a packet just 20 bytes, after to send 20 bytes data the fpga will output(PA6) a end packet signal to 68013, but I have modified the 68013 code, always can't succeed, so hope to get your help, thank you!

Dear Experts,

I am using CY7C68013A-56pin + FPGA for camera data capture based on slave FIFO interface. My pipe plan: IN: video data; OUT:  cmd data takes only few bytes and will be sent from host pc to FPGA occasionally. I refer EZ-USB TRM 001-13670_OE.pdf (page 30, Fig.1-17) for the endpoint buffer configuration selection. My question is that based on Fig.1-17, which configuration is the best for my project. Actually I feel #11 maybe the selection but my OUT data is only few bytes which will be sent occasionally only. So is there any other better selection for the OUT pipe? Actually I considered EP1 OUT but finally I found it is not included in the slave fifo interface. So I need your advices on this issue. Thanks.
