Why, after the first saturation of the timer, the code doesn't enter in the systik handler anymore?

[MPero]

I was trying to write a code to integrate a input signal, triggering the ADC with a timer, and print the information every 0.5 s with the systick. I don't understand why After the first saturation of the timer, the code doesn't enter in the systik handler anymore.

You don't handle/clear the CC2-CC4 timer interrupts you've enabled.

Sounds like it is stuck in interrupt loop.

Might also want to increase the priority of SysTick so it preempts other sources.

It's not a systick problem, couse i canceled the systick part e set the print flag with the timer itself, but after 130 prints, it stops to enter even in the main.

Remove this:

   TIM_ITConfig(TIM3, TIM_IT_CC2, ENABLE);

   TIM_ITConfig(TIM3, TIM_IT_CC3, ENABLE);

   TIM_ITConfig(TIM3, TIM_IT_CC4, ENABLE);

Thank you, now it works. I copied the configuration from a previous project and i didn't notice it.
