USB superspeed peripherals Forum Discussions
Hi,
Can I improve the download speed via interrupt endpoint (I am using it to configure FPGA), the same way that is explained in
http://www.cypress.com/?app=forum&id=167&rID=59529 or http://72.3.161.91/?app=forum&rID=63024 ?
I have four endpoints in total. Two bulk (slave FIFO GPIF) and two interrupt, I would like to improve the download speed of the OUT interrupt edn point, but when I configure the cypress with the img file, windows cannot recognize the device anymore.
Thanks,
Nazila

Show LessHi,
I am using slave fifo GPIF II. I would like to be able to discard (delete) the content of the GPIF FIFOs from CYUSB3014. I am using the "CyU3PUsbFlushEp" for both the producer and consumer. But the FIFOs stay unempty! How can I do this?
Thanks,

Show LessLooking at the supply bypass recommendations there are discrepancies hopefully someone can address. On the AN70707 HW Design Guidelines & Schematic checklist, Section - Device Supply Decoupling, U3TXVDDQ & U3XXVDDQ call for 22uF caps. However in the DVK schematics they are 2.2uF. Which is the correct recommendation? Thanks
Show LessFor the USB connections in the DVK board schematic, in page 9, the pins from FX3 side: SS_RX_P and SS_RX_N are connected to MICRO_SSRX- and MICRO_SSRX+ on the USB microB side respectively. Is this a typo? Or they have to be swapped for the connection?
Thanks.
Show LessHi,
we use SlaveFifoSync this example,How to clear the DmaChannel Buffer and Endpoint memory,
I use CyFxSlFifoApplnStop () andCyFxSlFifoApplnStart() to do, Spend a long time.
LIAN,Thanks.
Show LessHi,
The FX3API Guide says when I de intialize the SPI, the SPI is disabled and the power to the SPI module is turned off. Are the SPI pins in tri-state when this is done?
