I have purchased RL-ARM but I cant find the source code for TCPNet. Does it not come with the source code?
Thanks
"NicheLite is available royalty free with source code for the STR9"
Actually, I think NicheLite is available for use with any ST ARM-based microcontroller: http://www.stdownloads.com/
I think most chip vendors provide some sort of "free" IP stack; eg, Luminary seem to use uIP and LWIP.
Keil provides some more links here: http://www.keil.com/tcpip/
A previous client used CMX micronet - which seemed OK, and came with source, IIRC: www.cmx.com/micronet.htm
