I have compiled the module myself because there was no package available for the openwrt kamikaze 8.09 release, if you need it you can download it here so you don’t need to install the buildroot etc.or you can install the package directly.

opkg install http://blog.export.be/downloads/kmod-k8055d_0.1.2_2.4.35.4-brcm-2.4-1_mipsel.ipk
opkg install kmod-usb-uhci-iv

Like you can see I also installed the kmod-usb-uhci-iv package which was needed for the module to work. If all went well you now a /proc/k8055/0 directory with a file for every input and output. By reading or writing to these files you can read or write values to the board.
Next I wrote some misterhouse code to create misterhouse items for all the IO and the read and write commands to interface the files. Here is my code :
$k8055_out1 = new Generic_Item;
$k8055_out2 = new Generic_Item;
$k8055_out3 = new Generic_Item;
$k8055_out4 = new Generic_Item;
$k8055_out5 = new Generic_Item;
$k8055_out6 = new Generic_Item;
$k8055_out7 = new Generic_Item;
$k8055_out8 = new Generic_Item;
$k8055_in1 = new Generic_Item;
$k8055_in2 = new Generic_Item;
$k8055_in3 = new Generic_Item;
$k8055_in4 = new Generic_Item;
$k8055_in5 = new Generic_Item;
$k8055_out1 -> set_states (‘aan’,'uit’);
$k8055_out2 -> set_states (‘aan’,'uit’);
$k8055_out3 -> set_states (‘aan’,'uit’);
$k8055_out4 -> set_states (‘aan’,'uit’);
$k8055_out5 -> set_states (‘aan’,'uit’);
$k8055_out6 -> set_states (‘aan’,'uit’);
$k8055_out7 -> set_states (‘aan’,'uit’);
$k8055_out8 -> set_states (‘aan’,'uit’);
if ($state = state_changed $k8055_out1){
if ($state eq ‘aan’) {
file_write(‘/proc/k8055/0/out1′,1);
}
else {
file_write(‘/proc/k8055/0/out1′,0);
}
}

if ($state = state_changed $k8055_out2){
if ($state eq ‘aan’) {
file_write(‘/proc/k8055/0/out2′,1);
}
else {
file_write(‘/proc/k8055/0/out2′,0);
}
}

if ($state = state_changed $k8055_out3){
if ($state eq ‘aan’) {
file_write(‘/proc/k8055/0/out3′,1);
}
else {
file_write(‘/proc/k8055/0/out3′,0);
}
}

if ($state = state_changed $k8055_out4){
if ($state eq ‘aan’) {
file_write(‘/proc/k8055/0/out4′,1);
}
else {
file_write(‘/proc/k8055/0/out4′,0);
}
}

if ($state = state_changed $k8055_out5){
if ($state eq ‘aan’) {
file_write(‘/proc/k8055/0/out5′,1);
}
else {
file_write(‘/proc/k8055/0/out5′,0);
}
}

if ($state = state_changed $k8055_out6){
if ($state eq ‘aan’) {
file_write(‘/proc/k8055/0/out6′,1);
}
else {
file_write(‘/proc/k8055/0/out6′,0);
}
}

if ($state = state_changed $k8055_out7){
if ($state eq ‘aan’) {
file_write(‘/proc/k8055/0/out7′,1);
}
else {
file_write(‘/proc/k8055/0/out7′,0);
}
}
if ($state = state_changed $k8055_out8){
if ($state eq ‘aan’) {
file_write(‘/proc/k8055/0/out8′,1);
}
else {
file_write(‘/proc/k8055/0/out8′,0);
}
}
my $input;
if ($New_Second){
$input = file_read(‘/proc/k8055/0/in1′);
set $k8055_in1 $input;
$input = file_read(‘/proc/k8055/0/in2′);
set $k8055_in2 $input;
$input = file_read(‘/proc/k8055/0/in3′);
set $k8055_in3 $input;
$input = file_read(‘/proc/k8055/0/in4′);
set $k8055_in4 $input;
$input = file_read(‘/proc/k8055/0/in5′);
set $k8055_in5 $input;
#print_log “Input 1 is now $input1″;
}

Handles for the DA and AD ports are not yet implemented because I don’t use them for the moment.

Update : I just finished doing the same setup on a NSLU2 . I compiled the k8055 module via the buildroot for the ixp4xx harware. The only difference was that I had to use the kmod-usb-ohci_2.6.28.10-1_ixp4xx.ipk module instead of the uhci one. If anyone needs tha packages for the Linux OpenWrt 2.6.28.10 #2  armv5teb GNU/Linux NSLU2 harware let me know.

owserver

I installed the package owserver with the opkg command line tool

opkg -d usb install owserver

When the package was installed i started the owserver.

owserver – u -p 5555

On my desktop running ubuntu I installed owfs

sudo apt-get install owfs

which is the client for the owserver program and will create a filesystem whit all the sensors data.

sudo mkdir /mnt/ow
sudo owfs -s 192.168.1.1:5555 /mnt/ow

Works like a charm for me

Nice if you need to share your 1-wire data over the network but what i want is to have my temperature sensors values available in misterhouse that runs on the router as well.
So let’s go on to the next solution.

digitemp

Digitemp is another command line tool to interface a 1-wire network. To install type

opkg -d usb install digitemp

Let’s do a first test :

root@OpenWrt:~# digitemp_DS2490 -w
DigiTemp v3.5.0 Copyright 1996-2007 by Brian C. Lane

10F7709401080053 : DS1820/DS18S20/DS1920 Temperature Sensor
81E74C2A000000A5 : Unknown Family Code

That’s good ! Next create a conf file.

digitemp -i

Now you can read a value like this

digitemp_DS2490 -t 2 -q -c /root/.digitemprc
Feb 08 22:09:23 Sensor 2 C: 21.00 F: 69.80

All that we need now is some perl code to read the sensors values and store them in a misterhouse variable. I came up with the following code.

use vars ‘$tempsensor1′;
if ($New_Minute){
$_=`digitemp_DS2490 -t 5 -q -c /root/.digitemprc`;
/\sC:\s(.*)\sF/;
$tempsensor1 = $1;
print_log “Temperatuur is nu $tempsensor1″;
}

This is just some test code but it proofs that it works so I am happy for now.

Some months ago I discovered that the perl module named tv_grab_be which is part of the XMLTV software suite,  was no longer working. The site also indicates that the module is  “removed due to source site blocking ” So I start looking for another way to receive my TV listings. What I found was a much better and quicker tool. mc2xml is a tool to do the same but offers more powerful options like provider selection, channel selection, logo downloads etc … Even the Belgium TV Vlaanderen satelite provider is selectable from the list of providers and this perfectly what I needed.

If you are a mythtv user, this is a must have tool in my opinion.
