HI guys

I can simply not see why this is not working

volatile _Bool DitOn = 0;
volatile _Bool DahOn = 0;

void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)
           //DitOn = 1;
           //DitOn = 0;

This is working perfect....the interrupt callback retur to the main function and continue..BUT if i do remove my // so it have to set the to volatile vars it seams like IT DO NOT return to the main ???

Is there anything wrong here ?
