I'm doing above project in which i've to interface the pen drive to the microcontroller(PIC). I want to read the data from one pendrive and write it to another one. So can anybody tell me how should i interface a pendrive to PIC microcontroller..???
If anyone has this information for other controllers than PIC then they are also welcome..!!!!
Also help me about the file systems (FAT 32 or like that) to access the data in the pen drive..!!!!!
There are two methods that u can follow.
1) You have to use two microcontrollers 1 for read and another one for write in two different pendrives. The read data is transfered to another pendrive using serial communication TXD,RXD.
2) Another method is you can use a RAM. This method is usedfull in bulk data transfer. It is very fast. For this we have to use DMA concept. Once pendrive is connected read data first wait until it completes reading, then write on another one.
Thanx Paramaivan..!! I'm concentrating on the ur 2nd option as i've also thought of the same. can u please tell me how should i access the 2GB pendrive or of even lager memory than that? I mean to say that how should i access the externally connected memory in the form of pendrive..?? how would i know on which memeory location the data is stored in the PD..?
And one more thing..which controller would be the best if i've to configure it as a host and should also have the large enough Program Counter to access the memories ranging in GBs..??
if anybody can provide me the circuit diagram for the PIC 32 controller to be configured as the USB host...!!! please...!!
plaese give me circuit diagram of data tranfer between two pen drive without pc
Hi Mayur,
I hope the following link will help you a lot.

Hi Mayur,
You can try using SRAM from CYPRESS Semiconductors which are available in high density.
Hi Mayur,
Please note that both your pen drive and pic can act only as usb slaves. As far as I know, a slave can be interfaced only with a host and also there is no way of communication between two slaves without a host like your PC.
Plz help me in this project
Idea of the project is
pic microcontroller based circuit which read names of files from pen drive connected to USB to RS-232 converter. Display names on LCD connected to microcontroller.
keypad to scroll between nemes of files & to select a file on LCD. the selected file is send through RN-42
bluetooth module.
I want to use microcontroller kit/AVR kit as the circuit.
If anyone has code or any relevent info plz tell me
Thanks
Sunny
i am also want do project as same pls help me
