I can't get my Arduino Mega 2560 to work on my RPI.
The problem is the USB interface (no surprise there!) The Mega shows up as /dev/ttyACM0, and I've tried all the "workarounds" that I can find but it still doesn't work.
Has anyone actually got a Mega 2560 (R3) to work with a RPI ?

Re: Read serial port
That is a really bad example in that answer. It's not even a valid piece of C code, just a few lines of code that need to be wrapped up in a function, and the port needs to be opened and configured as well.

In which case you could be a bit clearer about it in your "PR blurb", especially as you say Rasbpian didn't have the stuff you wanted in it so you used wheezy instead !

There are a few in Colchester, Maybe we should just nominate a pub one evening and see who turns up.
Any nice pubs in Wivenhoe ? (I used to live there when I was a student).

Re: Static IP
In the general case your network address will be similar to your ip address.
So if
ip = a.b.c.d
and
netmask = 255.255.255.0
then
network = a.b.c.0
So if
ip = 10.0.1.XX
and
netmask = 255.255.255.0
then
network = 10.0.1.0

Raspberry Jam for Milton Keynes
The National Museum of Computing (TNMOC) located in Bletchley Park will be running its first "Jam" on the morning of Sunday 19th August. More details to follow, but the first event is aimed at gaining a feel for the level of interest in the local area.
