UPDATE: Due to the availability of low cost high power hardware these days (eg RPi), which was not available to hobyists when this project started, there's now a very limited need for this sort of networking stack; so development has stopped. It is still useful for educational purposes so will be kept online. Simple IP (sIP) is an UDP/IP stack designed for embedded devices, allowing small microcontrollers (8-bit) to communicate via Ethernet. The stack has been kept as simple as possible to ensure that it meets the strict size constraints of the target hardware (including 8-bit micros) and also allows students to study an entire stack without any additional complications. The stack is fairly lightweight and some features of RFCs may intentionally not be fully implemented to keep things simple (but still working!). The stack is ideally suited to projects where resources are scarce, and bandwidth is low. Common examples include remote control (eg home automation), data logging (eg weather stations) and servers (eg small web and time servers). The stack is not complete and is available online purely for reference. I do not have any hardware for testing, which is holding up development. With the arrival of devices such as the Raspberry Pi it's easier than ever to create small network-aware projects, so this stack may never get finished... Modifications are welcome, and code critique/review even more so. Notes about design decisions can be found in docs/NOTES.txt Regards Dave
