Hello, looking into the USBUART example firmware the interrupt endpoint is configured like this into the cyfxusbuart.c:
/* Interrupt endpoint configuration */
epCfg.epType = CY_U3P_USB_EP_INTR;
epCfg.pcktSize = 64;
epCfg.isoPkts = 1; <<---- IS THIS WROHG ?!?!?
apiRetStatus = CyU3PSetEpConfig(CY_FX_EP_INTERRUPT, &epCfg);
if (apiRetStatus != CY_U3P_SUCCESS)
{
CyFxAppErrorHandler(apiRetStatus);
}
As isoPkts option is only documented for isochronos endpoints, theoreticvally it should have no influence on the interrupt endpoints, somebody could please confirm that this is an error and eventually if something else nned to be done for a proper configuration of an interrupt endpoint.
Best regards,
MC

question1 :as following picture : Data is uping to the bus ,why the fifo addr is the same ? (where ?2 in the picture.)
2 in the article An65974 page22 : 5. sets up the DMA channels
a. For loopback transfers, short packet, and ZLP transfer, two DMA channels are created: why the buffer =1kB ? (for usb 3.0)
b. For streaming, two DMA channels are created: the buffer =16KB? (for usb 3.0) what is difference between the 1kB and 16 kB?
Hi:
The data is transferred from 3014 to pc. The configuration of 3014 is below:
1. DMAChannel with 1 producers(CY_U3P_CPU_SOCKET_PROD) and 1 consumer (CY_U3P_UIB_SOCKET_CONS_3);
2. 16KB buffer size in a DMA channel;
3. burst size is 16
FX3 transfers 16K data followed by 4B data continually using “CyU3PDmaChannelCommitBuffer”.
Two blocks(16K each block) allocated from USB host side to receive data from FX3.
I test it in Intel and Renesas controller, the result is pefect.but in Asmedia host I get 16K data, 4 data and a zlp,it is so wired, why receive a zlp ? how to solve it?
Show LessHello all:
I'm currently using FX3 receiver front-end transmission of data and the data transmission to the host computer. I use test data transmission speed streamer. Front-end FPGA data transmission is not continuous, therefore the data collected in the streamer timeout occurs frequently. Once streamer timeout, FPGA data can not be written to and loss of data, no matter how I set the streamer parameters, it will timeout! When this situation what should I do, how to set up? Thanks!

Show LessHello,
Am able to send a 4096 bytes to PC through Cy7C68013A from C8051f060. But i don't know how to use the control pins . I got the readings from microcontroller without connecting RDY pin and CTL pin , how can i send data according to CTL and RDY

Show LessHi, Sir
I'm a CyUSB.Net user. I use USBDeviceList and CyUSBDevice to Control my Devices. But i have a problem.
If i have a new device plug in, i can get a CyUSBDevice instance by:
CyUSBDevice mydevice = USBDeviceList[USBDeviceList.count-1] as CyUSBDevice.
if i go 4 mydevice, when i romved one from computer, how can i know which one was removed?

I have a FX3 DVK REV3 board. It gets supply from VUSB & J53 jumper is in place .PMODE signal setting is USB Boot (F11). I also edit cyusb3.ini file with VID=04B4 & PID=00F3, but it is not detecting on my pc which has winxp sp3 os.It pops up westbridge
every time I connect the board but enable to install its driver. Could someone help me, what went wrong?
Show LessAll,
There is an issue in the FX3 SDK 1.3.1 install which can cause a failure to launch eclipse, unless you have Java installed on your machines.
The workaround to this issue is to download and install the latest 32-Bit Java7 version from the Java website http://java.com/getjava/.
We are working on fixing the Java issue without needing to install Java separately and will have a release out by next week or so with the fix rolled in.
Thanks,
Sai Krishna.
