Raspberry Pi POE Hat Fan

Is there a way to enable to FAN on the Pi POE Hat in Emteria?

Comments

  • Find out how its done in raspbian and then see if you can translate that into the Emetria.OS

    I found this RPI Firmware patch which references boot/overlays/rpi-poe.dtbo but I don't see those files included in the latest beta distro.

    I'm not sure if its as simple as making sure you have all the required files or not and then running the "scripts" which control the cooling levels. Igor would need to comment on that.

    Do you have the POE hat running as is without any additional drivers?

  • Speaking of which, Igor do you have a tutorial (or can pull together one) on how we can compile our own drivers and attempt to implement support for external devices ourselves?

    For example on the question above, would we need to find the appropriately compiled .ko files for android or could we use linux compiled .ko modules known to be compatible with that specific kernel version.

    I think that would go a long way for users attempting to build in their own hardware support.

    How many folks are working at your company I'm sure they're very busy working on other issues, perhaps if users with tech skills helped build out tutorials of our own to get certain hardware working this could speed up the release/development cycles.

  • Assuming you ALREADY have the POE Hat overlay installed you can control it from the boot/config.txt file:

    Name: rpi-poe
    Info: Raspberry Pi PoE HAT fan
    Load: dtoverlay=rpi-poe,

    [=]
    Params: poe_fan_temp0 Temperature (in millicelcius) at which the fan
    turns on (default 50000)
    poe_fan_temp0_hyst Temperature delta (in millicelcius) at which
    the fan turns off (default 5000)
    poe_fan_temp1 Temperature (in millicelcius) at which the fan
    speeds up (default 55000)
    poe_fan_temp1_hyst Temperature delta (in millicelcius) at which
    the fan slows down (default 5000)

    We would definitely be grateful for tutorials by users.
    You currently have the option to post your tutorial here in the forum or in your personal blog. After a quick check, we would include it in our Documentations (https://help.emteria.com).

    I am not sure if there is a direct way for users to add tutorials in the Documentations. You should ask Igor if you are interested to build out the tutorials
