pendrive interface with 18f2550...

[demetal]

Hi,

i want to interface PIC 18F2550 with pendrive ..... and i want to store the data received via UART to pendrive.... is there any possibility for doing this.... please help....

I don't think so. Accessing the pendrive requires the PIC to be the USB master (host), but I think it is only capable of being the USB slave.

is it possible to interface SD cards.....

Absolutely, here's an appnote discussing the use of Microchip's SD/MMC File Library:

Datasheet and Schematics for SD/MMC PICTail Board

You can use the schematic for the daughter board above as a template to inteface the SD to the PIC.

you can use the vinculum USB Host Slave Controller module for this, see link FTDI Products

Using this module even the 18F2550 can be used, but I think it will involve some amount of software programming.
