uIP == TCP/IP in cooperative multitasking #3028

Open vanrein opened 2 years ago

As suggested on MCH2022, you may want to look into the TCP/IP for 8/16 bit microcontrollers, really small and pretty feature complete. There is now an IPv6 version too.

Oh, and you were surprised about cooperative multitasking in C, but it's done from time to time. Putty is the best-known example I suppose. It usually comes as very, very ugly header include files.

I really enjoyed seeing Go for microcontrollers, thank you for the idea and effort!

Worked on this for a while rolling my own a while back for the ENC28J60 IC. Was working okish, managed to get a basic http webpage to control a LED on the arduino uno. Still needed quite a bit of work to be extensible. I'll be taking a look at UIP since I'm still interested in having this feature.

@vanrein thank you for the suggestion! I haven't worked much on the net package but will keep it in mind as an option.
