Use PC Sensors with HAL was created by REEEN
Hello,
I read that it is possible to use PC sensors like the processor temperature sensor as hal pin,
but I don' t know how anymore.
Can somebody help me with an example or a step by step manual ?
Thank you !

Yes I have already seen this, but I can't figure out how to ude this script ?
Can you tell me what I have to do step by step ?
That would be awesome!
Thank you!

The instructions are in section 1.3 of that page, but may not be entirely clear.
If you look at the file itself you will see that it is a Python program. (The #! usr/bin/python in the first line of the file tells the Linux system what to run the file with).
So, you need to put the file somewhere where the system can find it, and tell the system that it is an executable file.
Also, just to complicate matters, the file is presented as a .txt file, which might cause confusion.
So, firstly get rid of the .txt suffix. This isn't strictly necessary, but makes the file look more like an executable than a document. You might prefer to do that in the GUI, with a right-click->Rename... Or if you want to use the command line:Then tell the system that it is an executable file. Again, you can do this in the GUI, as described here: askubuntu.com/questions/35478/how-do-i-m...executable-via-a-gui
orYou now need to "install" the file as a program where the system can find it. The probably is easier via the command lineIf you do want to do this via the GUI then you would need to run the file manager in sudo mode to have write-access to the /usr/local/bin folder. And you need the command-line to do that anyway (For future reference, "sudo nautilus" is the command)
You can test the new file at the command line in a HAL session (all the commands in a HAL file can be run "by hand" and it can be a useful way to test things out).The first command sets up a HAL session, creates the realtime system etc. The second command loads the new module, the third command displays the HAL pins that the module has created (make a note of these, you will use these in your HAL file), and their values.
If that all works, or if it doesn't, then typeto exit the HAL session and unload the realtime system. If it didn't work, then type "dmesg" to view the kernel error log for clues as to what went wrong (the problem will be described in the last few lines, the log begins from when you turned the computer on, so most of it won't tell you much useful about the HAL session)
If it is all working, then you can load the component simply by addingto one of your HAL files, then you can connect the HAL pins listed above to display widgets and other HAL objects.

It actually does more for you than it does for me. It appears to get as far as reading the data, but does not seem to create the pins.
On my machine it may even be slowly crashing the machine (not confirmed).
I will investigate further.

Hi REEEN, i wonder if you're accidentally running the wrong "sensors" program. There are two: the "real" one from the lm-sensors package, and the python hal component that you downloaded.
Try renaming the hal component from "sensors" to "hal_sensors", and load it with "loadusr hal_sensors".

I tried this and things worked a lot better.
However, I still got no pins because the output of "sensors" on my machine outputs two lines like this:
Core 0: +49.0°C (crit = +100.0°C)
Which do not match any of the regex patterns in the file.
It is probably a good idea to simplify the regexes to suit only the pins you want. And to make them suit the output from "sensors" on your machine.
Looking at the output I think you will get the fan speeds, but possibly not the temperatures as the regexes expect a "high" and a "crit" and you have "high" and "hyst"
I changed the file to read as follows, because I know I don't have any fans, and apparently have no voltage monitoring either:
And the output then was:
Owner Type Dir Value Name
5 float OUT 48 sensors.core_0
5 float OUT 100 sensors.core_0_crit
5 float OUT 48 sensors.core_1
5 float OUT 100 sensors.core_1_crit

def getSensings():
outputs = {}
sensings = commands.getoutput("sensors"); #run the sensors command from the lm_sensors package
#print sensings
line_list = string.split(sensings, '\n')
for line in line_list[:]:
line = line.strip('\n')
# e.g. Core 1: +25.0 C (high = +60.0 C, crit = +95.0 C)
m = re.match('(.*?):\s+\+?(\d+\.\d+).*?C.*?crit.*?(\d+\.\d+).*?C.*', line, re.I)
if m != None:
keyname = getKeyname(m.group(1))
outputs[keyname] = m.group(2)
outputs[keyname + "_crit"] = m.group(3)
continue
#print outputs
return outputs
And the output then was:
Owner Type Dir Value Name
5 float OUT 48 sensors.core_0
5 float OUT 100 sensors.core_0_crit
5 float OUT 48 sensors.core_1
5 float OUT 100 sensors.core_1_crit
