Hello I'm a newer to RL-ARM and I found that there're two wait function os_itv_wait and os_dly_wait in RL-ARM. Who can tell me what's the difference between them? For example is it possible to replace os_dly_wait(20) by os_itv_set(20); os_itv_wait()? Thanks.
Since it is a periodic timer, it counts from os_itv_set() and will restart continuously without any gap while your task runs.
Have you looked at the documentation in the keil directory on your hdd or the online manual on this site?
