Hi there:
Im new at this group, and quite new with ARM's too.
I need to send data from a PC application(made by me) to the uC, so i thought
about Ethernet communication.
I think 4mbps will do the job, at least for now. I've been searching in
the group messages and found some related
information(http://tech.groups.yahoo.com/group/lpc2000/message/39756).
Please, note that bi-directional communication isn't required.
By now(and maybe forever) the only devices connected to the physical layer will
be the ones mentionated before.
My only experience currently is with Code Red IDE.
What library would you recommend me to look at?
Regards,
Bruno.
Is it possible to get 4mbps from LPC1768 Ethernet module?

Third you say that PC has to send data to the LPC1768, so you would
estimate also how many bytes you have to send because at 4mbps the PC
will send 4/8 mbps = 500KB per second to the LPC1768 that hasn't the
needed ram, so your data rate couldn't be 4mbps (also if it is the
arithmetic media of the speed), you could obtain burst of 100mbps data
trains with also 0mbps pause but with a low duty cicle for a medium
speed lower then expected 4mbps. Could be a speed problem but surely it
is a big ram problem (with no solution using only the LPC1768 internal ram).
Just to be clear: with this type of microcontroller it is possible to
receive a limited number of packets in a second, generally their
application have to be designed to introduce a little overhead and with
not very frequently messages directed to them.
In this scenario 8KB of ram could accomodate a good number of ethernet
packets (depending on the size of the packets) but coud be filled in a
very short time in a scenario like yours (4mbps medium speed)
considering also the time needed by the management of the data contained
in the ethernet packets.
If 4mbps is a peak speed you would estimate the impact of these
parameters on the communication band i.e. in % of available througput.

I will send video RAW data. It's a live streamimg, well..almost.it will be 2 frames delayed.

Ok. Sorry for that missing detail. I would use 2x16(32kB)(double buffered) of RAM avaible to receive incoming data. The rest of the process shouldnt take a lot of time to process.

I could decide package size in PC software. I would try to use the largest size possible to increase speed.

Hi Leon.
Yes, USB was and still is my second candidate. Im a little afraid with USB because i need to be sure that packages will be sended. So, isochronous mode will be the correct one i think. Now, LPC1768 have a USB 2.0 Full Speed module with a maximum theorical speed of 12mpbs. Don't you think sending 4mpbs via USB wouldnt severely impact in OS(Windows only right now) performance?
Regards.

Bruno,
we've implemented the lwIP TCP/IP stack on a LPC2478 (which is defnitely
slower than a LPC17xx) and we get a throughput or about 2.5 MByte / sec
without using interrupts.

Hi Herbert,
I like the numbers you said.I will take a look at the lwIP library then. The code you mentionated is avaiable somewhere?
