Documentation Getting Started

Install Instructions:

The following assumes a 2.6 Linux kernel build 
from source. The following reference describes the
build process:

http://osdn.dl.sourceforge.net/sourceforge/souptonuts/README_26.txt


STEP 1:

 Edit the Makefile inserting the correct location of the 2.6
 source. Double check "/lib/modules/$(shell uname -r)/build". 
 
 KDIR    := /lib/modules/$(shell uname -r)/build

 If the above is not the correct location for the source,
 make the necessary adjustments.
 
 
 
STEP 2:

  $ make



STEP 3:

 Load the module as root.

  $ su -
  $ /sbin/insmod delcom806006.ko
	


STEP 4:

 Verify the module was loaded correctly,  
 "delcom806006 6656 0 - Live .." should appear in the
 following directory:

   $ cat /proc/modules

And "delcom806006" should also be listed after the following:

   $ ls /sys/bus/usb/drivers/



STEP 5:

  Commands to turn on the USB device:

   $ echo 80 > /sys/bus/usb/drivers/delcom806006/3-2\:1.0/minor
   $ echo 1 > /sys/bus/usb/drivers/delcom806006/3-2\:1.0/lsb

  Note, "3-2\:1.0" is the particular USB port my
  device is plugged into (Bus 3). You're probably using (Bus 1)
  or (Bus 2).

  For a listing of all active devices,

   $ cat /proc/bus/usb/devices 



STEP 6:

   After making changes to the "mybus" variable, the following
   programs should display the time on the USB device:	


   See "./user_land/bash/time"
   See "./user_land/C/prog1.cc"
   See "./user_land/perl/time.pl"
	
   

   Also checkout programming the device in raw mode


    Raw mode setting for the display
    
          ***(1)***
          *       *
         (32)    (2)
          *       *
          *==(64)=*
          *       *
        (16)     (4)
          *       *
          ***(8)***
                    * (128)
     
    To display an "A" .. (change 3-2:1.0 to location of device). 
   
    echo "1+2+4+16+32+64  "|bc > /sys/bus/usb/drivers/delcom806006/3-2:1.0/zero 



STEP 7: (Programming your own kernel modules)

  Sometimes it's nice to write to the active tty device. For a simple example
  of this checkout the latest version of procreadwrite:
    http://sourceforge.net/project/showfiles.php?group_id=79066&package_id=80379     

  special note: "current->tty" was replaced with  "current->signal->tty" in 
  the 2.6.6 and greater  kernels. Fedora Core 2 uses 2.6.6+. Downloading the
  above will demonstrate and further explain this.
