data transfer between two pen-drives using microcontroller……!!!

[jignesh]

i m making project of “DATA TRANSFER BETWEEN TWO USB FLASH DRIVES USING MICROCONTROLLER AND WITHOUT USING PC” .

if anyone has idea for this like : which controller i have to choose for it,how controller acknowledge about pendrive detection and data transfering then please do respond.

please friends help me for this project.

plz respond me on my email id : [email protected]

nice project jignesh… till now i had done intercaing b/w the host as pc and decive as microcontroller, pendrive, etc….
upto my knowledge you have to write own descriptor request which is send by pc when the device get pludged in… so that atlest the device will send you all the device descriptors…
what is the processing unit you using to interface two USB device..???
will be a bit complex… but really nice one
all d bst…

 i have search a lot but i m confused and at last i select max3421 and tusb2136 ,but later on i came to know that it is not useful for this.
i know i must have to use processing unit that has RISK architecture(atmel etc.) but i m only familiar to 8051 till now so it is difficult for me to use that .

if u have any idea about RISC and chip that is useful for this usb project then plz give me link of documents or mail me .

Thanking you.

it will not be a issue…. if you are well verse with 8051 you can easly switch over AVR
just refer to the link for avr tutorials

you can use 8051 too just refer to the link for 80512 usb interfacing it might be useful for you

hello…

 we are doing a project on pendrive to pendrive data transfer without using a pc..

 can u please give a code for it..

Hi all,

The PC has a USB controller chip and a program driving that chip (low level driver), also it has another kind of programs (high level driver) for accessing any particular kind of usb device and an application which make use of these drivers. You need all these things in your project.

You can make the task a lot more easy if you select any controller that has built in usb interface, like ARM9, ARM11 etc.
