Thread emulation layer provides RTOS-like thread abstraction on top of Contiki protothreads. The threads use a common physical call stack, exactly like the Contiki protothreads do, but the stack content can be saved in an external buffer at thread yield. The stored stack state can be restored later, emulating resuming of the thread. In general it resembles setjmp() / longjmp() semantic, but with addition to stack snapshoting and "return to jump point" functionality.
| #define EVE_THREAD_EMBEDDED_CSTATE 0 |
Normally disabled, reduces static RAM usage but increrases dynaamic one and CPU clocks required.
