HAL_TIM_PeriodElapsedCallback freezes when adding some content

[RPG]

I am getting desperate trying to solve this issue.

When I add some content to HAL_TIM_PeriodElapsedCallback the main loop gets frozen but still continue receiving call on HAL_TIM_PeriodElapsedCallback.

Could somebody help me out with this? I have been dealing with this issue for almost 3 days and don't know what could be the problem I have tried changing the priorities of the timers, prescales, moving functionality out of the timers IRQ handlers...

Thanks in advance.

Try decreasing the interrupt rate, i.e. increase (significantly - 10x or even more) TIMx_ARR or TIMx_PSC.

I tried by x10, x100 and x1000 and same thing. :(

Have also tried with several combinations changing the priority but nothing.

Never mind! Solved! It was a library imported from another project which was modifying the registers of one of the timers used on my project! It was driving me crazy... Thanks for the help anyway :)
