dallas 1-wire over gpio

[vbsaltydog]

I am running 3.7.2-2-ARCH and I want to connect dallas 1-wire devices to a designated gpio pin. I know there is a w1-gpio kernel module and owfs for referencing the detected 1-wire devices but I am not sure how much my arch build can do natively.

I dont want to add/configure kernel modules if there is existing support. Can anyone offer a detailed roadmap for running a 1-wire bus on a gpio pin and how to manage the bus devices (owfs?) for the 3.7.2-2-ARCH build?

I already have access to the gpios through /sys/class/gpio/gpioX so I dont need help with that aspect, just the 1-wire/gpio aspect.

Thank you

Shall I assume this is on Pi ?

[vbsaltydog]

negative. Its on the olimex maxi.

[WarheadsSE]

It does help a lot when you say which device you are using

[vbsaltydog]

Are you referring to the olimex or the 1-wire device?

The 1-wire device will be the

or similar.

I usually mean both pieces of hardware, so people have a reference.

[vbsaltydog]

anyone?

1-wire support is missing from the current linux-olinuxino package, so you'll need to recompile your kernel if you want the 1w-gpio module.

Still, WHICH olimex board? There are now:
- imx23
- a13
- a10s

[vbsaltydog]

The imx233.

I recompiled the kernel with 1-wire support and the 1wire gpio support as a kernel module but the module will not load because the gpio to use for the 1wire bus is not defined.

Does anybody know how to do that?
