USB low-full-high speed peripherals Forum Discussions
Hello,
When RS485 is enabled in CY7C65213A, according to the timing chart of the data sheet, the TXDEN signal seems to be active low (low at transmitting).
However, most RS485 level shifter ICs appear to require active high (High when transmitting) logic for the RE # and DE signals.
Do I need an inverter IC to connect these ICs?
Or is there a setting to invert the signal output of CY7C65123A?
Regards,

Show LessHi,
I just detected the KBA89285 -> https://community.cypress.com/docs/DOC-10959 and use the unique serial number in my firmware for a DSO. However, I wonder why this important functionality is not mentioned in the TRM.

I found this link and download the utility.zip but I am unable to extract it due to password, is there anyway I can unzip it? Thanks!

[CY7C65215-32LTXI] Automatically Set Device Serial Number
Show LessHi,
I am using the FX2LP board to capturing the image in CYUSB_LINUX(like data are giving, that we should seen in 'infile' window). After giving data, how we should store that data in file). Is their any procedure to store the data in file. (In linux ).

Hi;
I've been tasked with determining the suitability of using the FX2LP as a platform for implementing the USBTMC "Test and Measurement" class for a wide variety of instruments we design. The FX2LP would interface with a spartan 6 FPGA, which seems straightforward, and we'd obviously have to develp custom firmware for the FX2LP to implement the requirements of USBTMC. At first glance the FX2LP seems to have more than enough configurable endpoints to imeplement the standard.
I have a question about develpment tools however. It seems the development board kit for the FX2LP comes with a crippled version of the tools which are limited to a 4k output file. The website for the provided tools doesn't even have prices, which in and of itself a red flag, but other posts on the board indicate that the price for the un-crippled toolset is on the order of 2k/seat/yr, which is ridiculous.
Are there other development environments available? there was some talk in another thread about an eclipse-based toolset due out Q213? Is there any movement on that front?
Also, is anyone aware of any reference design which would help in implementing USBTMC on an FX2LP?
Thanks in advance,
ajm

Whether CY7C65211-24LTXIT support Andriod Driver for USB to UART . Do you have any Document and sample code for reference , Thank !!
Hi,
I followed the KB Drivers for EZ-USB® FX1™ , FX2LP™ , and FX3™ - KBA94413 to download Drivers.zip.
When I update driver through browse my unzip driver, Windows prompted "Couldnot find the driver for your device"
My device is a simple logic analysis 24MHz with CY7C68013A chip.
When I study this KB, it claims no need to modify INF (Adding the VID/PID is already done in the attached .inf file , so you can skip "Step A : Add the device's Vendor ID and Product ID to the CYUSB3.INF file).
What else I should modify in order to install device driver on Windows 10 x64?
By the way, I use USB 2.0 to miniUSB cable to this device. Don't know if I need to use USB 3.0...
Thank you,
Show LessDear Sirs,
What should I do if i want to use CY68013 in Slave FIFO mode to transmit Real-time Data that would be generated evry 50ns or 500ns?
Is the Isochonous transmission the best choice?
With bulk mode, the USB FIFO would be full and the real-time data would be lost, because the data can not write into the USB FIFO when the USB FIFO is full.
How should I do if we want the USB FIFO full flags not to be active?
And do you have the Isochonous mode example code?
Waiting for your reply!
Thanks~
Show LessHello,
I'm about to implement a software (C# Windows Application) to communicate with my I2C Hardware via a CY7C68013a.
I started using the CYUSB.dll and was able to find the USB Device. Unfortunately I'm stocked now.
How can I implement a I2C transaction between my software and the hardware?
Do you have a example for this?
Thanks a lot
Best regards from germany
