Feature request : w1-gpio kernel module

Hi, according current state of w1-gpio kernel module 1-Wire pin is hard coded to pin 4 which isnt practice for many standard use. I suggest to modify w1-gpio kernel module to be configurable using startup parameters. Patch and more description is available on post http://www.raspberrypi.org/phpBB3/v...

Thrue.
Please check http://www.raspberrypi.org/phpBB3/viewt ... 37&t=40044 thread for solution.

Re: Source code to w1-therm?

Hi all, I dont like idea that something not necessary is only hard coded in file without possibility to be change on execution time, so i change w1-gpio.c file and now w1-gpio module is configurable on execution time.

Hi,
nice to hear that sensor return predictable value :) ...

RPi use 3.3V and Arduino 5V input which may cause different. Do you use all 4 area on same time ?

Hi, In your schematic you use 2k2 resistor and 1uF capacitor, sensor is produced for 10M resistor and 100pF to 300pF, please read http://playground.arduino.cc//Main/CapacitiveSensor?from=Main.CapSense.

Hi, I got my Raspbery Pi few days ago, and found very unpractical that mounting holes are prepared for M2.5 screw. It is not any good reason for that, secure copper ring around holes is big enough to accommodate M3 screw without of any problem. With that improvement your board is usable and develope...
