smsfan 1.1.2

A set of functions to control Sequent Microsystems Smart Fan card

sfan

This is the python library to control the Smart Fan Card for Raspberry Pi.

Install

~$ sudo apt-get update
~$ sudo apt-get install build-essential python-pip python-dev python-smbus git
~$ git clone https://github.com/SequentMicrosystems/SmartFan-rpi.git
~$ cd SmartFan-rpi/python/
~/SmartFan-rpi/python$ sudo python setup.py install

If you use python3.x :

~$ sudo apt-get update
~$ sudo apt-get install build-essential python3-pip python3-dev python3-smbus git
~$ git clone https://github.com/SequentMicrosystems/SmartFan-rpi.git
~$ cd SmartFan-rpi/python/
~/SmartFan-rpi/python$ sudo python3 setup.py install

Update

~$ cd SmartFan-rpi/
~/SmartFan-rpi$ git pull
~$ cd SmartFan-rpi/python/
~/SmartFan-rpi/python$ sudo python setup.py install

If you use python3.x repace the last line with:

~/SmartFan-rpi/python$ sudo python3 setup.py install

Usage

Now you can import the sfan library and use its functions. To test, read processor temperature from the Smart Fan with stack level 0:

~$ python
Python 2.7.9 (default, Sep 17 2016, 20:26:04)
[GCC 4.9.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sfan
>>> sfan.getProcTemp(0)
31
>>>

Functions

setPower(stack, power)

Set the Smart Fan power

stack - stack level, set with jumper [0/1]

power - Fan power [0..100]

getPower(stack)

Return the fan power [0..100]

stack - stack level, set with jumper [0/1]

setSafetyTemp(stack, temp):

Set the Smart Fan safety temperature. If fan processor temperature exceeds this value fan will run 100%

stack - stack level, set with jumper [0/1]

tenp - Safety temperature in degree Celsius [30..80]

getSafetyTemp(stack)

Return the fan safety temperature in degree Celsius [30..80]

stack - stack level, set with jumper [0/1]

getProcTemp(stack)

Return the fan processor temperature in degree Celsius

stack - stack level, set with jumper [0/1]

setLedBlink(stack, blink):

Turn the Smart Fan led blink on or off

stack - stack level, set with jumper [0/1]

blink - Led blinking enable [0/1]

getLedBlink(stack)

Return the fan led blinking [0/1]

stack - stack level, set with jumper [0/1]

setStopInt(stack, seconds)

Set the stop interval in seconds. The fan will run 100% specified seconds then stop.

stack - stack level, set with jumper [0/1]

seconds - how long fan will run [1..65000]

getStopInt(stack)

Return remaining time until fan will stop

stack - stack level, set with jumper [0/1]
