smsfan 1.2.0

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

For Raspberry Pi 5 only, run the folowing:

sudo pip install SMsfan[rpi5]

or

sudo pip install SMsfan

or

sudo pip3 install SMsfan

Update

sudo pip install SMsfan -U

or

sudo pip3 install SMsfan -U

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

>>> 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]
