Re; Timers usage in CC2541

Hi
You can check SimpleBLEPeripheral project
osal_start_timerEx( simpleBLEPeripheral_TaskID, SBP_PERIODIC_EVT, SBP_PERIODIC_EVT_PERIOD );
It is a 5 sec's periodic timer

Hi Kimi
Thanks for the reply,


But actually I want to check the loop with in 5 sec's the osal_start_timerEx(); will go to the event after time expires but I want to execute the statements in 5 sec's.

Any solution or tell me how to use the Timers for this ?



Thanks in advance

Don't understand your requirement well. Can you elaborate?

Hi YC

Thanks for the reply

Actually I want to start the timer for 5 sec's within 5 seconds I need to execute all the statements.

As given above

(Timer start only for 5 sec's)
{
asm("NOP");
asm("NOP");
asm("NOP");
}
within 5 sec's all above statements should execute.

The thing is I am not getting how to start this timer in cc2541 which commond I need to use?


Thanks and regards

Jayaraj

Do you mean to block other thing and only process your statements for 5 seconds?

Yes exactly. But I tried using loops but its not upto the mark so I want to use timers.


With thanks

But if you block BLE device for 5 seconds, it would disconnect from central.

Hi YK Chen

Yes but I want to start the timer only once without connection so I want to use a "Timer for 5 sec's and execute the next few statements in that time".

Actually I want to check the interrupt status in 5 sec's if all the interrupts kickin in 5 sec's then I need to glow an LED, if I use osal_start_timerex then its going to event after timer expires but I need to check the interrupt status within 5 sec's only, if any other interrupt occurs after 5 sec's it is discarded.


Thanks and regards

Try to use the following API Onboard_wait, which counts in micro-second, in your while loop to count 5 seconds.

void Onboard_wait( uint16 timeout )
{
while (timeout--)
{
asm("NOP");
asm("NOP");
asm("NOP");
}
}
