USB low-full-high speed peripherals Forum Discussions

Hy everyone

I'm trying to send a signal from the ztex board USB-FPGA Module 2.13 using a USB 2.0 to the computer. From the side of the fpga, I'm using a fifo code, and from the computer side, I have a java code given by ZTex specific for communication with fpga. When I test if there is any informations received, i obtain this error that I don't really understand since this is the first time I test such programs:

Error: Error receiving data: Input/Output Error

Can you help me find a solution to this error so as I can send data from fpga to computer? Thanks in advance. Tell me if you need to see the java code and vhdl project. Thanks in advance

I have a folder driver for printer which is used for win 10 (intel) and they include 3 files: cyusb3.sys, cyusb3.cat, cyusb3.inf. I tried to install them on windows 11 arm-based but it says unable to find these driver. I have been searching long while and found out there is way to convert them to arm-based (I am not giving the link cuz this come from another site)

Can anyone please help me if there is a document or tutorial of this topic?

Kindly thanks for your support

Dear Friend

I want to build a data acquisition board with a FPGA sending data to PC via USB port.   I think CY7C68015A/CY7C68016A is a good choice for data transfer in between FPGA and PC.    But I never used this Cypress chip before,  Is there any direct reference design for me to have a quick adoption with minimum effort?

Thank you so much for your help.

Hello, I would like to ask what is the maximum sampling period for reading sensor data with cy7c65211A chip as the master and the corresponding sensor as the slave. Currently, while(1) the main cycle has been testing to read the data of a certain register of the sensor, the size is one byte, and check the pin waveform of MISO through the oscilloscope. It is found that the sampling period is only 400us-600us, is this already the highest sampling period? Please reply when you are free, thank you, and wish you a smooth work.

Hi, I'm using Cypress 68013 to transfer the data from Medical Device EEG amplifier to computer with high-speed USB.

When transferring, there is a high frequency knife working around the EEG device. The high-frequency electromagnet wave will interrupt the USB transfer.  

Would you please help to give some possible solutions to solve the USB working with the high frequency knife?

Thanks，

Hello,

While using a board using a cyusb3014 chip, I have a question about the debug interface in chapter 5.9, AN75779.

In general use,
When I download the firmware image to the I2C EEPROM, it appears on the FX3 on "other devices".
The update driver software changes the device to the Cypress FX3 USB Streamer Example and is available for normal use.

However,
If I change the device to the boot loader and download the same firmware back to I2C EEPROM,
the UVC camera retains the camera device, but the Cypress FX3 USB Streamer Example device is not maintained and is connected back to the FX3 on "other devices".

Is there a way to keep this as a Cypress FX3 USB Streamer Example? Even if firmware is downloaded again.

Thanks.
