With a CY7C65211 board and the example from the USB-Serial SDK spimaster, I am able to transfert 32k of data

from SPI EEPROM 25AA256 to the computer. But I only get 12Kbyte/s.

Should I get more at 3 Mhz ?

See attached code

 question1:

 What version of the software development environment does 63743 use? where to downoad? 

question2:

What simulator to programme 63743? like 68013?

question3:

which chip can perfectly replace 63743, our project is about  keyboard  mouse, so need  USB and PS / 2 port?

thanks.

Hi,

I am working with FX2LP. I have found examples relating to bulk and isochronous transfer, but not with interrupt transfer. Are there any examples with interrupt transfer, for windows side and FX2LP side?

Thanks,

Where can I see examples of CyUSB.dll call functions when programming in Visual Basic.NET?
Such examples are there?

The document "Cypress CyUSB .NET DLL Programmer's Reference" there are only examples for Visual C #
Thanks.

We are supplied by cypress with usb drivers ( inf, cat, sys). The desktop application I support is written with java so we use a install4j to create an app installer and we use a bat file to start dpinsta.exe to do the driver install. 

I  need some guidance on what is a better way to do this today?  I was poking around at Microsoft and the new windows 10 wdk. I also noticed that cypress  now provides a WdfCoinstaller01011.dll. How do we use this? How can i create a driver install package?

Thank you 

Hello!

The aplication note proposes to react to a flag within a single cycle.

When I take the Clock to FLAGS output propagation delay of 9.5/13.5 ns how am I supposed to react to it within one period of 20.83 ns without violating the 18.7/12.7 ns setup time of SLRD or 10.4/12.1 ns of SLWR? As this is clearly not possible and I have not found a single implementation caring, what would be the correct way to implement it?

Also I couldn't find any information weather it is legal to assert SLRD while the FIFO is empty or SLWR while full. Can anyone point me to that information?

best regards
Markus

If I have an instance of a CyUSBDevice from the .NET DLL, is there any way to pass this to a native DLL as a CCyUSBDevice?

I.e. can I convert a CyUSBDevice to a CCyUSBDevice?

i download the hex into fx2lp's ram ,but it can not function , so i use the oscillograph to view the waveform of  SDA pin.it shows that ,as long as i download the hex file into the ram using the control panel and click the reconnect button , the waveform is a endless square wave . after that, my control panel crashed. what should i do ???
