Occidentalis Kernel Module for PWM

Former Member

Hello!

I'm new to RaspbPi usage and i need to make PWM with a DC Motor.  I have an SD card with NOOBS and have installed Raspbian.

I have a kernel module from the Occidentalis distribution ( from Adafruit) that enables the PI to do that but i don't know how to install it in my PI.

Can anyone help pls?

    You can test if it loads with the insmod command.

     

    You must be root to load kernel modules.

     

    $ sudo su

    $ insmod /path/to/module.ko

     

    If it works you need to add it to your modules path so you can set up the configuration to load it each boot.

     

    You can if you want just add a symbolic link to your module file to the modules directory:

     

    $ sudo ln -s /path/to/module.ko /lib/modules/`uname -r`

    $ sudo depmod -a

     

    After that you can use the modprobe command:

     

    $sudo modprobe module

     

    Or add it to /etc/modules to auto load it at boot:

     

    $ sudo su

    $ echo module >> /etc/modules

    $ reboot

     

    You can test if your modules is loaded with the lsmod command:

     

    $ lsmod

    Module                  Size  Used by

    tcp_lp                 12663  0

    fuse                   86889  3

    bnep                   19624  2

    ....

     

     

    Hope this helps.
