People,I am implementing a "bare metal" (well not really, but that's not the point) system which is :
- non-preempting multithreaded (no other thread runs before a yield() or some waiting function)
- Single processor - All "threads" run with interrupts disabled - Interrupts have their own context And NO_SYS=1 on the lwip side.There are multiple threads but only one (the "main" thread invokes LWIP functions), and any "application" is using the RAW api (and is/are in the main thread)
My questions are :- How often should I invoke sys_check_timeouts() (every ms, every 10 ms, every second) - or (better) is there a way to determine (after any state change obviously) when the next timeout is due ?
- does sys_now/sys_jiffies have to be exactly milleseconds or would powers of 2 do ? (I have a microsecond counter and a 12 right shift would make a nice 1024 microseconds - making sys_now() sys_jiffies return the number of "1.024" ms... would that work ?)
Thanks, --Ivan
