How to Set CC3200 Timer A0 Interrupt Interval to 500us

Hi,

We have an existing project that sets the CC3200's timer A0 interrupt to 1 ms interval. The code is below:

Timer_IF_Init(PRCM_TIMERA0, TIMERA0_BASE, TIMER_CFG_PERIODIC, TIMER_A, 0);// Configuring the timerA0

Timer_IF_IntSetup(TIMERA0_BASE, TIMER_A, TimerA0Handler);// Setup the interrupts for the timer timeouts.

Timer_IF_Start(TIMERA0_BASE, TIMER_A, PERIODIC_1MS);// Turn on the timers

But we would like to change it to trigger every 500 us. Can you tell me how to change? Thank you.

Regards,

Tony

Hi Tony,

Use this code

#define USECONDS_TO_TICKS(us)   (80000000 * (us))

MAP_TimerLoadSet(TIMERA0_BASE,TIMER_A, USECONDS_TO_TICKS(500));
MAP_TimerEnable(TIMERA0_BASE,TIMER_A);

instead

Timer_IF_Start(TIMERA0_BASE, TIMER_A, PERIODIC_1MS);
