/********************************************************************
  How to make a driver for LCDproc

  Note: Insert the name of your driver in place of the phrase "new_driver".
  
  1. Copy drv_base.c and drv_base.h to new_driver.c and new_driver.h.

  2. Remove all functions which you *don't* need to override.
     lcd.h tells which ones you probably don't need to change, but use
     your judgement about which ones you need.

  3. Rename all functions from "drv_base_*" to "new_driver_*".

  4. Write the new driver functions.
     Be sure to call drv_base_close() in your new_driver_close(), to
     free memory used by the frame buffer.

  5. Add the driver to lcd.c, in the physical drivers section, protected
     by an #ifdef like the rest of the drivers are.

  6. Add your driver to the Makefile, in the same style as the existing ones.
