Htim- instance tim2
Web10 sep. 2024 · if (htim->Instance == TIM2) Am I correct to assume, regardless of which thread the timers are started from, the TIM callback will always occur "outside" of the RTOS environment? Yes, you are. The question who started the timer is not relevant to the context type/selection triggered by the timer. http://www.iotword.com/8673.html
