WebAnd the implementation of an interrupt function looks like this: void CInterruptVectorTable::IsrNMI(void) { pThis->virtualVectorTable.IsrNMI(); } So that will call a static method of another class (which can be private), which then can contain another static this-pointer to gain access to member-variables of that object (only one). WebThe MCU is an STM32L432. The button is connected to PB0. I want to use EXTI as the wakeup source from stop mode 2. I skipped the low power mode stuff for clarity. In the main loop I am polling the button. If it is held for more than 3 seconds I call this function: void power_shutdown (void) { volatile uint32_t x = 10000000; while (x--) { //ugly ...
