Re: How to mount 2 raspberry pi's to each other

DON'T USE CIFS. Use NFS (which is the native Linux network file system) and about 10^3 times easier to set up than CIFS. NFS uses the local security system on the shared drive. Thanks. Do you have an example line to set up /etc/fstab? I like to set up a mount from //192.168.2.185/home/ewh to /mnt/P...

Re: How copy 8Gb sd boot to 16Gb with maximum use of space

You could use Win32diskimager to write the 8gig image to the 16gig card. Then boot the Pi back up with the 8gig and put the 16gig card into a USB card reader, and plug it into the Pi. Then you can use parted to expand the partition on the 16gig. That should work. I do not have an USB card reader ;)...

How copy 8Gb sd boot to 16Gb with maximum use of space

Hello I do have a 8Gb boot SD card and want to copy/ clone it to a bigger 16Gb SD card using all the space off the 16Gb.
I like to do this on a windows machine.
I do know win32diskimager makes the 16Gb looks like 8Gb.
What steps do I need to do to organize this?

Thanks.

Re: more then 1 DHT22 sensors to Pi2

Thanks for the clear answer. I'm looking around the internet for a while and find a lot of information about reading DTH22 and ds18b20. The ansers are all slightly different. Addition to this question: I do like to write code in Python to read both sensors. The result I like to write into een logfil...

Re: Trouble reading USB0

I did install some debug sw in the program and found out that the p1 port sometime is sending out corrupted messages.
So it looks like it is no Raspberry Pi problem at all but the P1 port itself.

Re: Trouble reading USB0

EDIT: I do have an addition : The python program is also writing the data to the screen every 5 minutes. By using the crontab command, the writing to the screen is not happening. Can this causing a kind off stack/buffer overflow, because the writing data is stored somewhere, by not displaying? Prog...
