How to enable interrupt function in sw4stm32
<p>I use  SW4STM32 toolchain,I want to bliking led using timer2 when overflow, in STM32103RET,
here is my functions to turn led on and of.</p>

<pre><code>void TurnOnLed(){
    HAL_GPIO_WritePin(GPIOA,GPIO_PIN_10,GPIO_PIN_SET);
}

void TurnOffLed()
{
    HAL_GPIO_WritePin(GPIOA,GPIO_PIN_10,GPIO_PIN_RESET);
}
</code></pre>

<p>the timer2 initilizing has been set by stm32 cube mx, but i do not know which function called when timer2 overflows?</p>
