Device Driver-LKM ( Loadable Kernel Module ) - Kernel Driver

This repo includes 3 projects.

  • simple_module: Hello world project.
  • char_drvr1: character device null driver which needs manually created /dev file.
  • char_drvr2: character device null driver which creates /dev file automatically thanks to udev.

All projects are tested on RapsberryPi. To test IO functionality, $echo and $cat commands can be used.
