Has anyone tried serving up compressed javascript on their web heavy Netburner applications? It doesn't appear as though the javascript code is compressed in any way, a 90k JQuery package really eats into my flash budget. As as aside, what are folks generally using for 2d line graphs? I was just goi...

Definitely less than 1 millisecond for a typical 64 node 100Mb/s network. It's hard to make any other sort of determination without details. The key questions are: * How many packets are in flight to the master and slave at any give time. The netburner needs to empty it's Ethernet receive queue, and...

I think what ridgeglider is referring to is using the serial ports as higher speed interfaces to external hardware running at 1Mb/s per. 115.5k would be at the low end of that scale. I didn't find the baud rate limit in the freescale docs, but I believe it was pretty high. In that case saving to on-...

Yeah, you lose the descriptor so you can't close it on the client end. It's kind of a long standing issue with telnet and ftp servers. Most of them are smart enough to timeout the server socket so you don't exhaust the servers pool of available sockets. You could try using a keepalive option on the ...

I always have non-blocking server loops. This is entirely possible with the netburner, but not by using accept(). You need to use the ZeroWaitSelect() api. What you need to do is call ZeroWaitSelect() with your listen socket in your receive FD_SET to listen for incoming connection requests. Once sel...

You'll need to convert your raw number stored in nbval to ascii text for display (http://www.manpagez.com/man/7/ascii/). In C you'd use printf, itoa, or stringstream. No idea what you got going with basic, but I'm sure there's an equivalent.

Wow, .90 is a seriously good deal. I ordered 1+ of everything

Netburner uses the 74lvc16245 as it's bus interface to the on-board cpld. I'm working on a similar design, and am trying to breadboard up a prototype. It's a pretty wide chip, and all of the ssop to dip packages I have are too narrow. What do you folks use? I ended up sawing a smt protoboard in half...

This is interesting. It looks like it returns >0 if the socket is open, and the underlying send() call succeeded, which usually always happens if the socket isn't full. Reasons for failure would be: Socket closed - probably returns 0. Socket error - Some errno less than 0. To tell if the remote end ...

I'd like to handle physical link up/down events so I can monitor network state. It looks like I can stick a callback handler into ethernet.cpp : ProcessDuplexStatus() to do this, but I was thinking there was already a supported method, but darned if I could find it. Does anyone know if there's alrea...
