Timer in CC2538

Other Parts Discussed in Thread: CC2538, CC2541

1. I want to use the timer to create a delay function. I have read the peripheral library document. But i didn't get, if i set a timer of 10 Sec, how i will get a call back after 10 Sec. I want to use Timer rather than osal_timer. Can any body suggest me to this

2. If i am building the source from scratch for CC2538, what are the things i need to do.

Can any any suggest me how to start a timer and set a ISR function to know timer expires in CC2538. I have implemented the driver for starting Timer and ISR function of Timer in CC2541. But in CC2538 User Manual i couldn't understand.

1. You can refer to gptimer example. It will be under C:\Texas Instruments\swrc271a\cc2538_foundation_firmware_1_0_1_0\driverlib\cc2538\examples\ if you install cc2538_foundation_firmware package.
2. I suggest you study all examples in cc2538_foundation_firmware package first. By the way, why do you want to build everything from scratch?

Yikai, I have been to that. I have seen the driver to start and set a Timer. But, for example if i set a Timer for 1 Min, after timer Expires, how will i get to know(I mean, where is ISR function for 3 TImers)

If set a Timer and enable the Interrupt by calling below functions

TimerConfigure()

TimerControlEvent()

TimerIntClear()

TimerIntEnable()

TimerEnable()

But where will get a interrupt. I need to write ISR function. If yes, can you suggest me how.
