DATA TRANSFER FOR USB STORAGE DEVICES USING MICROCONTROLLER

1. ‘USBee’
A bridge for USBs
“You want it???
Then just Cross it!”

2. Got a USB?

3. Usual Method of
transfer

4. Why you need it?
Do you always have a computer or a laptop around
to transfer your data from one USB to another?
Do you have a fear of loosing your data?
Do you have a fear of a Virus Transfer while
transferring your data?
Do you get to transfer your data from one USB
to another without facing the troubles of- “ACCESS DENIED!!”
as permission required??

5. Is transfer of data possible Without the pc ?

6. Solution to ‘your’ NEED
 Portable and eco-friendly(power supply-9v).
 Fast data transfer(512 kb/sec).
 Transparent transfer
 No access rights
 Custom user interface

7. General Architecture

9. NTFS FILE
SYSTEM
AND
IN SYSTEM
PROGRAMMING

10. FILE SYSTEM
• What is file system?
A file system is a method for storing
and organizing computer files.
• Why we require it?
The data they contain to make it
easy to find and access them.

11. FEATURES OF NTFS
FILE SYSTEM
• Increase reliability
• Increase security
• Support large volumes
• Allows long names

12. HOW NTFS WORKS?
Organization of an NTFS Volume

13. MASTER FILE TABLE
System File File Name MFT Record Purpose of the File
Master file table $Mft 0 Contains file record for
each file and folder
Master file table
mirror
$MftMirr 1 It is a duplicate image of
the first four records of the
MFT
Log file $LogFile 2 for faster recoverability

12–15 Reserved for future use.
17 Onwards for each file and directory

14. IN SYSTEM
PROGRAMMING
• In-System Programming allows
programming and reprogramming of any
microcontroller positioned inside the end
system
• A way to serially program your
microcontroller
• It save time and money

15. HOW PROGRAMMING TAKES
PLACE
3 SPI wires
1. Serial Clock (SCK)
2. Master Out- Slave In
(MOSI)
3. Master In – Slave Out
(MISO)
• Reset line-For serial
programming mode.
• VCC

16. BOOT LOADER
AND
UART SERIAL
PORT

17. BOOT LOADER

18. WORKING OF A BOOT
LOADER

19. STEPS TO BE CARRIED
OUT
STEP 1 :The bootloader gets programmed
in the program memory.
STEP 2: The incoming data is written in the
program memory.
STEP 3: The bootloader executes a jump at
the first instructions of the regular
program.

20. System Architecture

21. File system controller

22. USB Controller

23. User Interface Controller

24. Data Flow and Control Flow

26. Future Modifications
 Allow data transfer between pen drives in any memory format.
 Multi-Pen drive transfer.
 Bluetooth or other wireless technology.
 Allow file encryption.
 Multiple use.
