We are trying to upgrade our ezusb device(cy64613) to ezusb fx1(cy64713) for 64bit windows.
Our windows app has been developed using CBuilder2007.
1. Previously
For this old device control,
First got handle for device using CreateFile windows API
and used deviceIOcontrol API with taken handle.
In our case for devicename \\\\.\\ezusb-0 is used
i.e.
Handle=CreateFile("\\\\.\\ezusb-0",.....) for getting handle.
Then
what name has to be used for new device ezusb fx1 or fx2?
2. Referring to TRM
for getting device handle using CyAPI
USBDevice= new CCyUSBDevice( );
can be used.
But
When trying to above using CyAPI.lib(for BC6)( taken from installed Cypress Suite USB 3.4.7)
Alaways access vilation error happened!!
Please help me!!!

Hello,
Please use the CyAPI.lib from the FX3 SDK which contains the latest library files.
Once the FX3 SDK is installed you can find the library files in the path: <installation directory>\Cypress\EZ-USB FX3 SDK\1.3\library
The API document "CyAPI.pdf" is present in folder path: <installation directory>\Cypress\EZ-USB FX3 SDK\1.3\doc\SuiteUSB
Note: for the CyAPI.lib to be used, the device should be bound to the cypress cyusb3 driver.
Using the CyAPI library:
A device instance should be created using the CCyUSBDevice class.
example: CCyUSBDevice *FX2 = new CCyUSBDevice();
This will not return a handle to the device yet.
To get the handle to the device you can either use the Open() method with the device number as an argument. If only one cypress device is connected to the host then you can direct pass 0 as an argument.
example:
if (!FX2->Open(0))
{
printf("open failed\n");
//exit(0);
}
printf("device opened\n");
Once the device is opened you can use the DeviceHandle() function to get an handle to the device opened.
example:
HANDLE handle = FX2->DeviceHandle();
Please refer to the attached host appication, which detects number of devices bound to the cyusb3 driver and opens device 0, prints the VID, PID in decimal and the number of endpoints, of the device connected.
