When adding a new time in the program, the register cannot be written during initialization. The reason is that the relevant initialization is not performed and a register is not enabled.
The procedure is as follows:
void HAL_TIM_Base_MspInit(TIM_HandleTypeDef* htim_base)
{
//GPIO_InitTypeDef GPIO_InitStruct;
if(htim_base->Instance==TIM7)
{
__TIM7_CLK_ENABLE();
HAL_NVIC_SetPriority(TIM7_IRQn, 0, 0);
HAL_NVIC_EnableIRQ(TIM7_IRQn);
}
else if(htim_base->Instance==TIM3)
{
__TIM3_CL K_ENABLE() ;
}
else if(htim_base->Instance==TIM1)
{
__TIM1_CLK_ENABLE();
}
else if(htim_base->Instance==TIM2)
{
__TIM2_CLK_ENABLE();
HAL_NVIC_SetPriority(TIM2_IRQn, 1, 0);
HAL_NVIC_EnableIRQ(TIM2_IRQn);
}
When adding the enable operation, if the time is defined to generate an interrupt, you should also add the red font as shown above.
