2.2.3 void os_setcallback(osjob_t* job, osjobcb_t cb)

預備一個可立即執行的 job. 可隨時call os_setcallback, 即使是從 interrupt handler

( e.g 感測值更新)

2.2.4 void os_settTimedcallback( osjob_t*, ostime_t time, osjobcb_t cb)

在指定的 timestamp call callback

exp

os_setTimedCallback(&sendjob, os_getTime()+sec2osticks(TX_INTERVAL), do_send);

sendjob :  job control struct osjob_t 指標,  typedef osjob_t osjob_t

do_send  : callback

typedef int32_t ostime_t;
