I'm using Jessie on a Raspberry Pi zero.
I'm trying to get it to have a static ip address.
I understand I need to edit the dhcpcd.conf file but it says 'permission denied'

can anyone helpl?

WE have a raspberry pi model 2b
The 8x16 matrix that we have is http://www.amazon.co.uk/DIYmall-Matrix- ... B0126B7YH2

Can anyone give us a clue how to start to get this connected and what we need to do to make it be able to display characters.

many thanks
