在STM32F103C8T6上使用HAL库进行定时器中断的方法是通过以下步骤实现的:
1. 首先,你需要在main函数中开启定时器中断。可以使用以下代码开启定时器1中断:
HAL_TIM_Base_Start_IT(&htim1);
2. 确保APB2时钟的频率设置正确。在STM32F103C8T6上,APB2时钟的频率为72MHz。这可以通过以下代码来设置:
RCC_ClockConfigTypeDef RCC_ClockConfig;
RCC_ClockConfig.APB2CLKDivider = RCC_HCLK_DIV1;
RCC_ClockConfig.APB2CLKType = RCC_CLOCKTYPE_HCLK;
HAL_RCC_ClockConfig(&RCC_ClockConfig, FLASH_LATENCY_2);
这些步骤将使你能够使用HAL库在STM32F103C8T6上实现定时器中断。这样,你就可以使用定时器来执行你所需的操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
