Conclusion

The solution provides a way to add Ethernet connectivity features to STR710 with minimum

resources load. It uses a minimal part of one chip-select addressing space of the EMI and

since it is hooked to the RTC alarm, it is possible to calibrate the CPU load for its

processing. The stack also supports SLIP protocol; in this case it also commits the UART0

resource. The user can easily customize the application by modifying just three files. In the

end, the firmware uses little of STR710's memory resources: 65.04 KB of Flash and 7.16 KB

of RAM, correspondingly the 25.4% of the Flash and the 11.18% of the SRAM; of course

these values depend on the files size of the web server that are variable.
