Other Parts Discussed in Thread: CC3200

Hi everyone,

I'm writing a program that use the cc3200 timer.

I've set up the interrupt for the timeout event of TIMER A with and associated handler that do some operations,

but I need for set up another handler every clock cycle that the timer count.

How I realize that?

I noticed that the function TimerIntRegister register an handler for any timer interrupt, but I want distinguish interrupt type.

The timer example in the SDK shows how to use 2 different interrupt handlers, it uses different names....I believe the handle names are you choice.

Otherwise, if you are ok with using TI-RTOS, then you can setup as many Clocks as you want and trigger these in various ways.

Hi,

Not sure I get you. Can't you use something like (below)?

MAP_TimerIntRegister(TIMERA0_BASE, TIMER_A, TimerA0IntHandler);
MAP_TimerIntRegister(TIMERA1_BASE, TIMER_A, TimerA1IntHandler);
MAP_TimerIntRegister(TIMERA2_BASE, TIMER_A, TimerA2IntHandler);

Regards,
Gigi Joseph.

Have you looked at the timer example in the SDK?

Hi,
I've tried to set another timer that starts when the other starts.
For this timer I set the mode as TIMER_CFG_ONE_SHOT|TIMER_CFG_A_CAP_COUNT
and then I set interrupt handler for this timer,
and then I enable interrupt TIMER_CAPA_EVENT, but unfortunately, when I start the timer, it doesn't print nothing every time it counts.

I looked the timer example for realize the actual timer and it works fine, but in the timer example doesn't print something for any time it counts.

I solved by setting the timer interrupt every 1 seconds and updating a global variable in a cycle,
but now I have a problem, because I must receive some packets during the timer count, so, I want open a thread
to handle timer count. How I open a thread or task in an osi task with free_rtos?

Hi,

Please see the "freertos_demo" example application (processors.wiki.ti.com/.../CC32xx_FreeRTOS_Application).
