TDA2x one-shot mode timer

Other Parts Discussed in Thread: SYSBIOS

I need to do something exactly in the middle of each frame.So I plan to start a timer(one-shot mode) in the VSYNC interrupt callback function and I should get an interrupt when the timer is timeout. Then I can do something in the timeout interrupt.

How should I quickly do this? Are there any similar examples that I can refer to? Or, should I use sysbios to realize it ?

Thanks.

on IPU1_0, I use ti.sysbios.timers.dmtimer.Timer to realize it. I got an assertion error, prompting that Timer not available, if I do it after CaptureLink_drvCreateInst() or CaptureLink_drvCreate(). Where should I do the timer params initialization and timer handle create ?

hi
you may not really need a new timer here, use bios clock object for your purpose. for sample code to set-up clock object refer nullSrc Link
