Hi,
In my application, i need a accuracy timer to turn household appliances on/off every day.
For example, turn on refrigerator at 13:00 and turn off at 18:00.
I use the timerapp client to get the current time when connect to service, then use osal_start_timerEx() to time the current time after master is disconnect.
When i set osal_start_timerEx() to 1 hour time out (timeout parameter is 3600000), it generate time-out event is about 1hour and 15 ~ 20 second.
In other words, osal_start_timerEx() have about 0.5% error every hour.
This is not acceptable in my application.
so how to improve the absolute timing accuracy of osal_start_timerEx()?
Or any suggestion is welcome..
Many thanks!!
