This project gives an entire view of how to create a Character_Device_Driver in Linux(Ubuntu). Create a Driver Module. Build the Driver Module using Makefile. Create user interface for the same(here it has been created via a C program). Insert the Driver Module. Take the concerned inputs via that interface and perform the read,write and close operations. Close the module and Remove it. One can use the same PC for the creation and application of the module . Suggestion :A test PC would be better for application.
