Hi
excellent guide
I completed the installation
we can say that everything is working

thank you very much !

[robgreen]

ok
I’m sorry if I reply yet…
but the first 8 are
(first 8 pins on the 3.3V column): 1, 3, 5, 7, 9 (Ground), 11, 13, 15. stop

I hope 17 is free, otherwise, I do not have to give pin power 3V…

ok thanks
I’ll try the solution

the dubious was
to be obliged to use the pins in the same column 3.3V

so I understand that I can use

pin 17 3.3v
pin 20 ground
pin 22 GPIO25 (with edit config parameter)

and the same is my problem …
I wanted to use GPIO interface 4 That is to Dallas DS18B20 1-wire temperature sensor

I wanted to connect to the pins free of raspberry specifically …

PIN17 3.3V
PIN25-GND
and
GPIO4? which alternatives???

OSPI 1.4 uses the first 8 pins on the 3.3V column … and the first 5-pin on the 5V column
see attached image

someone was able to use the digital sensor DS18B20 with OSPI ??

I am terribly sorry I didn’t see what was straight in front of my eyes…..

remains the rule that the pins occupied by OSPI

I can not share them with other sensors??

thanks so much for your reply

[robgreen]

I’d like to implement this project
http://blog.turningdigital.com/2012/09/raspberry-pi-ds18b20-temperature-sensor-rrdtool/
It is possible …can be done using pin other than those listed??

some advice….:)

[robgreen]

I apologize ….
I made a mistake …
I have not clearing the cache browser…

now works correctly!!
