USB superspeed peripherals Forum Discussions

Hi, 

I would like to read/write from/to the differential SBU lines. Is there a component to translate the differential lines to a serial-type interface ? or do I need to configure it as GPIO and do SW bit banging ?

Thank you!

Hi,

I have a software built in C#. It bulks out a 16-byte data to an Fx3 device and the from start of Xfer() it measures the time until it returns true.
I measured it to be 600 us. The FX3 contains the firmware of Asynchronous Slave Fifo for GPIF II.

Next firmware is a loopback firmware from AN70983. I also used the same software to bulk out the 16-byte data and measure its time. The bulk out time is 50us-90us.

My question is as follows:
1. Why is the amount of bulk out from the Asynchronous Slave Fifo super slower than the loopback firmware?
2. What are the possible ways I could boost the bulk out speed of the Asynchronous Slave Fifo for GPIF II Firmware?

I recently got a the CYUSB3ACC-006(1) interconnect board.

The CYUSB3ACC-006 has 180 pins. But my Altera board (SocKIT) has a 160 pin HSMC connector. Are these compatible?

Hi,

I tried the USB audio example to work under Linux for 16kHZ sampling referring some other post in this forum.

I changed the descriptors and CY_FX3_ISO_XFER_LEN in the code for 16kHZ sampling and it started streaming the audio from SPI flash. But the audio is breaking and looks like elongated (may be because of multiple copies of same audio samples).

Do you have a working example for Linux platform for 16kHZ?

Hi

I added a new Product ID in cyusb3.inf file. and I should install modified win 10 driver. but modified driver is not loaded with hash error.

"The hash for the file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering "

Please let me know how to do I something. host is windows 10.

Regards

Shin.

When i am compiling fx3 dsk firmware i got follwing error 

eclipse  unrecognized command line option -std=gnu11 

how to solve problem

Is it possible to configure the GPIF II interface on the FX3 to act as a UART at 1 Mbps? How would that be accomplished?

Hi,

Can I have an infinite transfer AUTO DMA channel from SPI to USB end point. Is it possible to make the transmission happen only if fixed number of bytes got received from SPI each time?

Any example source code to evaluate?

I'm trying to build the example code for AN75779, but I get an error:

$ make arm-none-eabi-gcc -g -DTX_ENABLE_EVENT_TRACE -DDEBUG -DCYU3P_FX3=1 -D__CYU3P_TX__=1 -I. -I~/cypress/cyfx3sdk/fw_lib/1_3_3/inc  -O0 -Wall -mcpu=arm926ej-s -mthumb-interwork -ffunction-sections -fdata-sections -c -o uvc.o uvc.c uvc.c:56:24: fatal error: cyu3system.h: No such file or directory  #include <cyu3system.h>                         ^ compilation terminated. make: *** [makefile:55: uvc.o] Error 1

Is the cyu3system.h header file only included in a specific version of the SDK? I have 1.3.3.

Thanks!

Dear Cypress,

I would like to customize Slave FIFO project by adding a input control pin.

Is it possible to initiate data transmission through GPIF from external device to the End-point when the rising-edge on one of the GPIF pins is appeared? Besides I need to transmit a strictly defined amount  of data (probably I need to use counter in GPIF designer) and then I want to go back to waiting  for the rising-edge state.

Which pin of GPIF for such input I should use?

Thank you!
