Portable Data Transfer

Abstract

Our project aims to design an embedded device that allows one USB pen drive to transfer file to another USB pen drive without using a Personal Computer. Now a day’s portability is most important. So to achieve this, we are designing such a system which can be carried out anywhere. Traditionally, we used to transfer data between two pen drives by using laptops or desktops. But it is not always possible to carry such a large size device to the particular location. So to solve this problem, we are designing a hardware which is more compact to carry anywhere. With the help of this project we can not only transfer the data but also we can see the transfer of the particular file which we want to send by using LCD TFT display interface. In our implementation, we are transferring the data between two pen drives without using any computers or laptops. We have designed a project which is known as “Portable Data Transfer”, in which we will be transferring the data between two pen drives using Raspberry Pi. Raspberry Pi uses its ARM processor which is very powerful and capable of perform various tasks [4]. In the block diagram we can observe, Whenever we insert the pen drive into the USB port then a signal will be sent to the ARM processor indicating that sender’s pen drive is inserted so now ARM processor will start fetching the data from the sender’s pen drive into the buffer and it will perform any selected operations like Copy, Paste Delete and thus after that ARM processor waits for the signal from destination receiver’s pen drive. Whenever ARM processor gets the signal from the destination pen drive then ARM processor is ready to transfer the data between those. Thereafter the ARM processor should get the input from the user externally, once the user gives the input then the ARM processor gets the information to transfer the data between two pen drives [2][4].
