Is it possible to change declaration of HAL_GetTick () to int32_t and not uint32_t ?

Hello,I use signed integers since a long time in delay calculations using 16 or 32 bit counters.Indeed, it suffices to do a simple signed subtraction between the two counter values to obtain an exact delay even if the counter has looped back in the m...
