PIC32MX675F512 is a single device, until they can build the metal box on si=
licon.  If you need anything like it in PCB, figure about 3x the money.

Looks interesting,
but I really do not know Python, cannot even read it.

What you describe is some server running that accepts commands via TCP and then changes the GPIO pins,
maybe does things itself too.

Well, there are places (directories) where to put startup scripts that would start that server.


There are 2 possibilities,

1)
does your application run its own thing, for example read a pin and set a relay,
or read an ADC or some sensor and set some other thing in sort of a loop?
Then it needs to run constantly and be started at power up and provide for example a little webserver for users to control things.

2)
But if you just want to be able to remotely control a relay,
then you can remotely start the application with ssh -Y with for example as command line arguments the relay number and state, from any PC

In both cases or rather in my case I would write some C code.

Writing that stuff is simple, *once you have done it...*
These are controlled via ssh:
 http://panteltje.com/panteltje/raspberry_pi/
 http://panteltje.com/panteltje/raspberry_pi_noppp/

I do not have a server example for Raspberry, but there are plenty for PC on my website that should just compile on the Pi.

On the old website I had Apache server running and some cgi scripts to control some I/O.
I am sure Apache runs on raspi too.

I also had some script that runs constantly and listens for video stream using netcat on the raspi.

The possibilities are infinite....



So it all depends on your programming abilities and preferences.
Could be that link you gave does everything you need.

Could you please provide a datasheet? This one says:

http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en545644

*USB* PHY and ethernet *MAC*.
I.e. nothing special compared to most of ARMs.

	Best regards, Piotr

Have not look in detail what are needed for straight ethernet.  But we use a $4 USB to ethernet adapter:

So, for $10 we have an IP server with ethernet.

Look for ENC28J60 based modules. 
In Germany there exists a board with ENC28J60 and Atmega called avr-net-io which is
very popular. Kit price is about 20 EUR.

It's also only got an Ethernet MAC. The PHY has to be added as an
external chip with a bunch of connections (between 7 and 16, depending
on the type of interface used).  

AFAIK, there's only one chip in Microchip's line with an on-board PHY
(PIC18F97J60 with a 10M PHY).

Does Microchip provide sample code for this kind of application? I
guess you need to allow for both the USB and Ethernet stacks, and some
additional software?

OK, it does add $1.20 for the Phy and $4.78 for the Jack.  So, the $4 USB/Eth is cheaper and we can also use the USB for something else (flash drive).

PIC32    6.50
