Why do we need this STM32_TimerInterrupt libraryFeaturesThis library enables you to use Interrupt from Hardware Timers on an STM32-based board, such as STM32F/L/H/G/WB/MP1.As Hardware Timers are rare, and very precious assets of any board, this library now enables you to use up to ...

The real power of hardware timers is however in the way they can send interrupts to the CPU eliminating the need to check the status manually. Add the following function to your code and call it frommain()afterInitializeTimer(): void EnableTimerInterrupt() ...
