Re: ssh client application not working with Raspberry Pi 3

I'm pretty sure ssh works fine on the Pi 3. Assuming you are using Raspbian Jessie. It works fine for me and I'm sure we would have heard lot's of complaints from others already if there was a problem with it. Suggest getting a non-broken ssh client. Better than downgrading security on your Pi. Put...

Re: Create a new I2C in raspberry Pi using normal GPIO pins

Thanks to your reply.
I don't understand it clearly about the I2C in parallel port. It is complicated to use the I2C of camera module. Is there any future issue to use only two(CLOCK, DATA) GPIO pin for I2C communication in Raspberry Pi.

There is a sudo raspi-config advanced option to do so.


Thank you...

That worked after changing the advance option settings and restarted the system

Thank you again. I didn't noticed this option before.
