WebMay 27, 2024 · As the timer callbacks are called from the Timer Service task, it is important that the callback function does not block (e.g. waits for some time or waits for a semaphore), as otherwise all other timers get delayed. So the general rule for a timer callback function (as for interrupt service routines) is: keep it short and simple! Starting …

WebExample 3: Timer Interrupts. Timers can be used to trigger a variety of interrupts (see section 72.2.9 of the HAL/LL API reference document for a list of possible HAL-supported interrupt callbacks). We will use a very basic interrupt: when the timer reaches its maximum value, it will rollover back to 0 and trigger an interrupt. WebNow, to my understanding, the ISR register holds the flags of which interrupts has occurred; and the IMR holds the mask (which interrupts the user enabled). the AND product of both will tell me which interrupt has occurred. In addition to the ISR information, there are the CallBack events and the "Event" and "EventData" that are sent to the ...

Now imagine the DMA finishes transfering: the DMA will call " HAL_ADC_ConvCpltCallback ", BUT since we also enabled global interrupts for the … WebCallbacks are done under interrupt context so will inherit the priority/preemption level of the calling IRQ Handler. I would be very careful to keep the highest priority interrupts doing the least possible work, and deprioritize those doing heavier work. Don't dwell in interrupt context, so no delay loops, polling on status, etc. ...
