w1-gpio-cl's Issues

Modify timeout value for 1W device scan

Hey,

I'm using this driver on my Jetson Nano computer to work with W1 devices. It has w1_master_timeout value set to 10 s by default. It is too little, and I would like to change this value to 1 s. Could you pls tell me how to configure it?

Compilation Prerequisite Details?

Hi, This 1-wire bus driver looks exceptionally usefull, if I can get it to work!
I'm trying to get two 1-wire interfaces to run on a Pi Zero without major re-work of the operating system, and your work here looks like exactly whats required.
I tried to run the following via terminal on a freshly installed copy of the latest Rasbian jessie (25/11/16) on a raspberry pi zero;

sudo git clone https://github.com/pstolarz/w1-gpio-cl.git
cd w1-gpio-cl
modprobe wire
sudo make
insmod ./w1-gpio-cl.ko m1="gdt:GPIO1"

However as you can see from the log below, the Make process failed, and w1-gpio-cl.ko was not produced. I guess that this is because I've not provided the prerequisites you mention in the README. Assuming this is the case, any chance that you could include a more step by step guide in the README? or point out the thing I'm doing wrong?
Many thanks in anticipation!
Richard

`gen-mast.h' has been generated.

NOTE: The compiled module needs w1 set of headers, which is a part of the internal
(not the public) part of the w1 API. The headers are contained in the full Linux
kernel source tree.
Since the kernel sources has not been detected on this platform, the compilation
process will use headers which are part of this source bundle (included in
./w1-internal directory). Linux kernel API is not persistent across versions, so
it is STRONGLY recommended to set ./w1 symbolic link to `drivers/w1' subdirectory
of the target kernel sources. This way proper w1 headers will be used.

Build error on Fedora kernel 6.6

Running Fedora on kernel 6.6 and I'm getting the following error:

NOTE: ./w1 symlink is already set and will not be updated. Remove it and restart the compilation process in case you want to re-run the kernel sources examination.
