Hello.
I did test I2C/SPI interface with CYUSBS236 Kit.
I want to change dev type (I2C / SPI / UART) without cypress configuration util.
because new board will be made with CY7C65215 + Another chip and be controlled cfg/protocol with new MFC tool in Win OS.
(We not have plan to add ROM for CY7C65215)
So Is there any method to change dev type and protocol parameter value in code level?
Linux library have functions expected change it , for example , CySelectDeviceType / CySelectInterface .
But windows library not has symbol of that.
I did already search about this question.
Below ticket not have any solution for question.
Re: CY7C65215 - Programming the configuration flash
Please let me know how to set configuration in windows code level.
Thanks,
- Windows OS
- Control and Set CY7C65215 with new MFC tool.
- We can't reuse cypress cfg util.
- We need API (or lib) to change configuration value.
Show LessHello!
I'm working on a a project using the CY7C65211A as a CDC USB-I2C Bridge. This is something I actually have successfully done, but over a year ago, so with all the Cypress USB Drivers present on my system now, I think windows is installing the wrong one. What I'm finding is I can connect with no problems to the Vendor MFG interface to configure the device, but I'm unable to actually use it as a CDC interface. The Cypress USB Serial Test Utility shows the following:
The device is also not found by the Bootloader Host Utility in Creator 4.2, and attempting to write I2C with the cyusbserial.dll library in my .NET bootloader application gives me CY_ERROR_REQUEST_FAILED, which seems to point to it not being recognized as a proper CDC USB-Serial device.
In device manager, I can see the MFG device, as well as the USB-Serial device:
I had thought the driver at:
C:\Program Files (x86)\Cypress\USB-Serial SDK\Cypress USB-Serial Driver\DriverBinary\CDC_Driver\bin\win10\x64
was the one I should be using, but I still am unable to find the device in the test utility.
Would anyone be able to point me to the correct driver I should be installing for the CDC device?
Thanks!
[EDIT]
Something I forgot to mention, last time I was working on the CY7C65211A I was using Win7 x64 and now I am on Win10 x64.
Also, checking the event viewer I found this warning every time I try and change the driver. Possibly related?

Show LessHi,
I want to send the commands from GUI--->FX3--->ZYNQ(like $ZYNSAEC9945678#94!), in this FX3 will act as a 'master' and ZYNQ will act as a 'slave' and again i have to slip this ZYNQ to 'master' and FX3 as a 'slave' to getting the commands given form GUI side.
I getting the commands upto from GUI to ZYNQ, but i am not the getting the commands from ZYNQ to FX3. can you help to solve this problem?
Attached the FX3 file and ZYNQ file.

Show LessHi. cypress
customer use CY7C65642 to design in two ports HUB(current pending 2ports). according to newly datasheet, I will let customer modify R121 650R to 649R.customer use VUBS 5V to supply the IC, whether the SELPWR(Pin 22) to connect with VBUS or without any GND or VDD? do you have any other advice base on schematic.
thanks

Show LessHello,
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?

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!

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 !!
