USB low-full-high speed peripherals Forum Discussions

I used to make a product using CY7C63723C-SXC IC the program used was an assembly.

  its purpose is usb to ps/2 converter and it has a separate cpu on the output ans. so it drives the keyboard ans mouse.

  currently,the cy7c63723c-sxc is called the production stop.

It you want to use the cy7c63310 ic,  how should you use it.?

1. copy the existing data to the cy7c63310 without changing it.  do i have to change only i/o port from pcb.

2. or Should i re-programme to cy7c63310?

3. do you have a tool that converts automatically?

4. our company doesn't have enough people to do asm, is there another service company?

    ofcouse all have all  source problom

5. the best way is there is a way to get about 500pcs

Dear all,

Is there  USB to I2C configuration file of CY7C65215?

Also, are we able to update the F/W of CY7C65215 through USB?

Thank you，Shun Furusawa

Dear Technical team,

Please clarify the below issue.

CY7C68013A-56PVXI 6 CYPRES 18+  We sold this part to customer, but the end user said there isn't any output of the PCB board when test it with pluging in the USB. PC failed to read the chips when connect to PC with USB. The end user is asking if it need any configuration to connect via USB to computer. The end user configured VID, PID via C51, but failed as well. He downloaded the chip's keyboard driver program as well, but failed. Is there any port which needs to be set up in the configuration of C51?

The end user checked the soldering of the goods, the Peripheral circuits, the PCB board and the USD connector as well, but all of them are fine.

Your Support is Greatly appreciated.

Regards

Ravi

Hi Guys,

i'm new in using the EZ-USB FX3 SDK on an analog Device evaluation Board ADF4159. I want to develop a matlab Script that can be used to configure the board without a user intervention.

I find on others forum some codes that allows me to the CyUSB library. Actually i can connect To the board with the following command matlab script

:

try

  CyUSBdll = NET.addAssembly('C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\application\c_sharp\streamer\bin\Release\CyUSB.dll');

catch error

     error.message

     if(isa(error,'NET.NetException'))

        e.ExceptionObject

     else

        disp('CyUSB.dll already loaded');

     return;

     end

end

% Create a list of USB devices

usbDevices = CyUSB.USBDeviceList(CyUSB.CyConst.DEVICES_CYUSB);

% USB Device Count

num_usbDevices = usbDevices.Count;  % <=== returned 1 when the device is plugged in, 0 when it's not.  

usbDevice = usbDevices.Item(0)     

Firmware_Path = 'C:\Program Files (x86)\Analog Devices\ADF4158-9\adf4xxx_usb_fw_2_0.hex';

if (~isempty(usbDevice))

    disp('Device Connected succefully !')

   % Load the firmware of the device ADF4159

    FirmwareLoaded = usbDevice.LoadExternalRam(Firmware_Path);

    % usbDevice.Reset();

    % usbDevice.Dispose();

end

My question is how can i write to the register of the ADF4159 (https://www.analog.com/media/en/technical-documentation/data-sheets/ADF4159.pdf).

i tried this example in Matlab, but nothing seems to happen. Have you some idea of how i can shape data and send it to the component?

for ii = 1:4

    buffer(ii) = uint8(0);

    usbDevice.ControlEndPt.Target = CyUSB.CyConst.TGT_DEVICE;

    usbDevice.ControlEndPt.ReqType = CyUSB.CyConst.REQ_VENDOR;

    usbDevice.ControlEndPt.Direction = CyUSB.CyConst.DIR_TO_DEVICE;

    usbDevice.ControlEndPt.ReqCode = uint8(hex2dec('DD'));                      %% DD references the function in the firmware ADF_uwave_2.hex to write to the chip

    usbDevice.ControlEndPt.Value = 0;

    usbDevice.ControlEndPt.Index = 0;

    buffer(5) = uint8(32);

    buffer_length = 5;

    XferSuccess = usbDevice.ControlEndPt.XferData(buffer, buffer_length);

end

Hope somebody can help.

Best regards !

Hello,

    How to change the exposure in FX2LP by using SET command from GUI? (is this only when AEC disable)? what all registers i must change?

Thanks&Regards

Hello..

We are working with FX2LP in this I am considering 3endpoints 2IN and 1OUT Endpoints i.e 6 and 2 as IN endpoints and 02 as OUT endpoint,it is working fine only for control center side,the fx2lp receive the data at the end point 2 it gives the OUT data at control center in this case in GUI side the image is not going to display instead of this it showing a black screen when I am considering the endpoint 04 as OUT it display the image what it captured by sensor but in control center it is not giving OUT data instead of this it showing an 997 error.

what is reason for this?

Thanks & Regards

I would like to get a documentation on I2C communication as I am trying to know how the data is stored in EEPROM in EVAL-AD5933 evaluation board.

Link to the datasheet of EVAL-AD5933:

https://www.analog.com/media/en/technical-documentation/data-sheets/AD5933.pdf

Or the source code of the above mentioned.

The cy7c68013 chip I used cannot work in isochronous transmission mode, but it can work in block transmission mode. Computer software I cannot obtain data with CyConsole.exe and the software I designed, nor can I obtain data with Bus Hound software. Now you can provide me KEIL's ISO mode routine for my reference. There seems to be something wrong with the CyStreamer routine you gave.

I have got a FX3S RAID-on-Chip USB Dongle and I'm using FT232H from adafruit to debug via UART but I don't know why debug messages doesn't appear on TeraTerm I also tried displaying using Putty but still didn't work. I did the following:

1- I installed necessary uart to usb bridge adafruit driver and did a loopback test and it worked.

2- I double checked the connections between the RAID-on-Chip USB Dongle and adafruit UART to usb converter(Tx, Rx and gnd) and they are ok.

3- I used the following setting to display debug messages using TerraTerm (baud rate 115200, 1 stop bit, Data 8 bit, no stop bit, no flow control)

But debug messages never displayed!

Any helpful reply would be appreciated
