I cant get the STM32F746 timer tick interrupt to work even though I have followed the chain to the tick ISR. Comments in the code are a bit unclear too.
/** @addtogroup HAL_Private_Variables
__IO uint32_t uwTick;
* @brief Provides a tick value in millisecond.
* @note This function is declared as __weak to be overwritten in case of other
* implementations in user file.
* @retval tick value
__weak uint32_t HAL_GetTick(void)
The uwTick is in private section. But I don't know what it really is. In the code it is said to be a global variable but it isn't because if I use it in my main.c, I get an undeclared error.
By the way, I'm trying to make my own callback work. Similar code has worked before but not now.
(volatile int own, own2=0;)
//uwTick++; //uncommenting this gives an error.
