USB low-full-high speed peripherals Forum Discussions
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?
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.
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.
I'm using CY7C65215-32LTXI in our design.
I have changed the configuration like following by using USB-Serial Configuration Utility.
After this change, there have been no device detected by usb-serial configurariton utility. And also device manager could not detect com port.
Please tell me the way to back the configuration under this circumstance.
Hello, I would like to ask how many slaves can be connected when the cy7c65211a chip uses SPI mode as the MASTER. Some of the data taken by my channel is old and distorted, I would like to ask what the reason is, hope to reply when you are free, thank you.Show Less
