Hi,

I am about to start a project which will require ethernet connection and 
I am kindly asking you for some advices on the following topics:

1)  On the HW side I will probably go with a LPC213x controller plus an 
ethernet controller. There is a very interesting, low pin count 
controller from Microchip (ENC28J60) which is pretty new. Any 
experiences with it or do you suggest some other controller ?

2)  For the SW side I will use a RTOS which has a TCP/IP stack build 
into it, taking into account I am not a TCP/IP guru. My options are uIP, 
lwIP or OpenTCP for the open source stacks. I know they are all good 
stacks, but maybe do you like one in particular and why ? If I go with a 
commercial stack the options are very vast. Any experiences ?

Thanks in advance for sharing your experiences !

Regards,
Marko

  I believe MicroChip has a stack for the ENC28J60 available for no cost
as long as it is used exclusively with their part.  Another thing to remember
though is the ENC28J60 is a 10 Mbps part, not 10/100 and is also reported
to a bit of a power hog (I recall seeing reported current draw of 250mA).
Another option is the Iinchip WizNet W3100A connected via I2C.  It requires
an external PHY but has the stack built in and supports 10/100 operation.
I've been working on an eval board with the 2138 and the W3100A in my "spare"
time for a while.  The boards I have now have a couple of blue-wires but
they are functional and I have at least the low level interface software
operational.
