I haven't but I'd like to know what can be squeezed in. My bet is, ICMP only over UDP using a PPP type interface over serial link. Even so it will be hard to leave room for an ant or two in the smaller PICs (without external RAM/ROM). Peter

I think that PPP can be done, but i don't if it's worth to do it... my bet is UDP, ICMP, IP over a SLIP link on a pic 16F84 running at 19200 bps... i'm sure it can be done.. TCP is far too complect to be implemented on an 8 bit architecture with small memory storage like a pic... it would be REALLY fine to use some kind of bus instead of a point to point interface like SLIP... it isn't easy but it could be done... my problem is that i've no time at all... on a bus interface one could get in trouble when some kind of broadcast messages are posted on... or if a message is on the bus while the pic is doing some other things... also CSMA/CD is a big issue... with bit banging it can be done easily.. i was also thinking about adding an external ram/eeprom to store incoming messages until they're parsed... then the receive routine will be interrupt driven... but a very full bus will not allow the pic to read the stored messages without lossing some packets ..then you need a way to syncronize with the bus .. in fact, it's not easy.... -- - *Alex* - http://freepage.logicom.it/azummo/
