/* A dummy function for the case when additional interrupts are not used in the project.
In the project, you need to create a function of the form:
extern "C" void ISR(void)
{
// timer16 is taken as an example
if (TIM16_GET_ARRM_INT_STATUS(htimer16_1_))
{
// necessary actions
}
// reset timer interrupt flags
TIM16_CLEAR_INT_MASK(htimer16_1_, 0xFFFFFFFF);
}
before that, be sure to connect the libraries:
#include "mik32_hal_timer16.h"
#include "mik32_hal_irq.h"
#include "wiring_LL.h" */
} }
