How to set set timer for 15 second in TM4C123 Tiva launchpad

sivaprasad sm

Hai,

Please let me know how to calculate the value loaded to the function TimerLoadSet(TIMER0_BASE, TIMER_B, SysCtlClockGet() / 1000); for a required duration and processor clock frequency. for eg: 1 sec

Thankyou,

Hello Sivaprasad,

The 32-bit times have to be loaded with a value of 15 times the System Clock. When you load the return value of the SysCtlClockGet it will amount to 1 second.

Hi Amit, I honestly do not envy you for having to answer this (and similiar) questions ...

What has become of the good old "RTFM" answer ... ?

Hello Sivaprasad,

Counters-101: Please read the data sheet for timers and see how counting is done.
