No, not in the Designer Environment per se. You have to write C code to create that

capability and address the device drivers needed to communicate to the file server. Or

use the SDCARD library and modify it to handle your specific file device.

Dana,

Device Drivers means,For this am using USB Interfacing with CY8C20666A to the System,Can you send me the sample code or any document Please..

I am not aware of any drivers to do this, other than the SDCARD code to implement a

FAT file system, and that will not run on the part you are using do to its RAM / ROM limitations.



Maybe someone else knows of something.

Bhupati,

so not to misunderstand you:

You want to open a file in the "System". What do you understand under "System"?

You have got a PSoC1 and... ? A PC?

Then the PSoC1 will be connected to the PC-Host and there is no way for the PSoC to "open a file". Only the host can do that and then send the data to the PSoC via USB interface . USBUART could be an easy-to-use component, but I'm not quite aware whether available on your chip.

Edit: No, there is no USBUART on your target chip, only a USBFS (FS = Full Speed), so you'll have to implement the protocol yourself.

Or send the file via whatever method (UART, I2C USB bridge, SPI) to PSOC and its SDCARD interface, then open

the file under the SDCARD FAT APIs.

Bob,

Thank you for reply, System means PC sir.

Am using USBFS only for this interfacing CY8C20666A to PC-Host.

Now am trying to write a code for my own protocol like sending some of the commands to open a files in the PC by using the part CY8C20666A with USBFS,

have you any idea give me a good suggestion sir.



Thanking you,

Bhupati.

So you will have to program an interface on your PC for sending the file contents to the PSoC.

What are the data you send and what are you going to do with them on the PSoC side? When you tell us a bit more about the project we will be better able to advise you.

Python for PC side or VB probably fastest way to do this.
