OpenFSG

Hi,

finally i was able to get Debian running on the FSG.

Can anybody tell me how the LED's, buttons, and the EL-ring can be used or is this also "top secret" like the fan controling?

Hi,

what info do you need? I have no problems with giving out hardware info. Even the fan stuff is out there. Somewhere

Kind regards,
Robert

I really need the fan info. That's the one thing which is preventing me from keeping the FSG3 turned on and active as a development platform. The current fan control is just too binary and too noisy when it's binary "1" We need a fixed half-speed, or a smoother continuously variable transition between fan speed (not sure if that is possible with the hardware, which is why I'm looking for the hardware info).

Actually, the most useful thing would be the source code for the fan daemon, but I am aware that Freecom has no obligation to provide that (as I doubt it is GPL'd, and it's a stand-alone daemon so it falls under the mere-aggregation clause of the GPL and is not infected) - it would simply be a great community gesture if they did

Hi Robert,

it would be nice to know through which device they are controlled.
And if there is already a free driver for it.

As far as I know it uses Hotplug?
But with Hotplug from Debian there is no reaction.
So it need to be modified?

Hello developers,

concerning the fan. It is controlled by the "fand" daemon. If you don't
run it. You gain absolute control over the fan. You really do not need
the source code of "fand", believe me. It is a very simple program
that only reads and writes /proc entries.

The real code for that is in the kernel. The fan is connected to the
"PWM1" pin of the monitor chip W83782D.

To know how fast the fan should run, read the temperatures:

cat /proc/sys/dev/sensors/w83782d-i2c-0-28/temp1
cat /proc/sys/dev/sensors/w83782d-i2c-0-28/temp2
cat /proc/sys/dev/sensors/w83782d-i2c-0-28/temp3

The last number of the output is the temperature in degree Celsius.
Compare them with the ones on the "Hardware->Fan Control" page.

To get the fan speed:

cat /proc/sys/dev/sensors/w83782d-i2c-0-28/fan1

Again the last number is the speed in rpm. Compare it with
the one on the "Hardware->Fan Control" page.

To change the fan speed, first read it:

cat /proc/sys/dev/sensors/w83782d-i2c-0-28/pwm1

The first number ist the PWM level. Type:

echo "0 1 1" > /proc/sys/dev/sensors/w83782d-i2c-0-28/pwm1

to switch the fan off. Type:

echo "255 1 1" > /proc/sys/dev/sensors/w83782d-i2c-0-28/pwm1

to put it to full speed (9000rpm). And type:

echo "50 1 1" > /proc/sys/dev/sensors/w83782d-i2c-0-28/pwm1

to get a moderate (silent) speed.

That's all to report about. Have fun and good luck !

Bye,
Michael

Hello again,

I have forgotten to tell you that the fan infos above are only for
kernel 2.4 !

In kernel 2.6 you need to use the sysfs:

cat /sys/class/i2c-dev/i2c-0/device/0-0028/temp1_input
cat /sys/class/i2c-dev/i2c-0/device/0-0028/temp2_input
cat /sys/class/i2c-dev/i2c-0/device/0-0028/temp3_input

for the temperatures (values must be devided by 1000 to get the
temperature in degree Celsius).

cat /sys/class/i2c-dev/i2c-0/device/0-0028/fan1_input

for the fan speed, and finally

cat /sys/class/i2c-dev/i2c-0/device/0-0028/pwm1

for the PWM level.

Bye,
Michael

Thanks Michael! That's exactly the type of information I was looking for.

Can you tell us whether the CASEOPEN# input and/or the BEEP/GPO# output of the W83782D are connected to anything (e.g. one of the buttons on the front, or perhaps available on one of the internal connectors) ?

Thanks again,

-- Rod

Hello,

the pins CASEOPEN# and BEEP/GPO# are not in use and are NOT
connected to any connector. BEEP/GPO# is connected to an beeper
that is not placed in the mass production samples.

Bye,
Michael

Excellent. That means that the pad for BEEP/GPO# may be accessible for someone who wants to solder on a general purpose output

Thanks again for the information, Michael. Based on your fan information yesterday, my FSG-3 is now running 24x7 in the lounge room, and I have used that fact to finish the development of the optware packages bootstrap script.

-- Rod

Now that we know how to control the fan via /sys, does anyone know how to control buttons and LEDs? I.e., to bind custom actions/programs/scripts to each button, and to be able to power on/off the LEDs?

Helo developers...I've been searching for some info about some commands to turn off or turn on the fan of me fsg-3 (I have the 4.2.7 version).
I have being reading this thead but in my fsg I don't have the proper directory ... Do you know the commands to change the speed of the fan?
Sorry about my english and thanks in advance.

Hi u,

try login in as root, then you will see the directories.

Kind regards,
Robert

Hi rbar,

I have Debian installed too in one of my FSG, and I'd like to be able to turn on and off the leds.

Is it possible?

thanks in advance

Hi Pakillo,

absolutely.

Do a search, all the info on how to do it should be out there.

Kind regards,
Robert
