STM32输入捕获回调函数未触发问题求助（Nucleo-G070RB + STM32CubeIDE）

各位大佬好，我现在用Nucleo-G070RB开发板配合STM32CubeIDE做项目前期测试，卡在输入捕获的定时器回调函数触发这里了，折腾好几天没解决，求帮忙看看！

我的测试逻辑很简单：

1. 麦克风模块的数字输出检测到声音时会产生上升沿
2. 希望定时器的输入捕获功能检测到这个上升沿后触发中断回调
3. 在回调函数里设置一个标志位mic1Triggered
4. 主循环里检测到标志位就切换LED状态，同时重置标志位

目前已知的情况：

• LED硬件连接没问题，直接在主循环里写HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_2)是能正常闪烁的
• 麦克风模块确实能输出上升沿（模块自带的指示灯会亮，说明有信号输出）
• 我换了3个不同的定时器通道测试，结果都是回调函数没触发
• 已经在代码里调用了HAL_TIM_IC_Start_IT(&htim1, TIM_CHANNEL_1)开启中断模式的输入捕获

下面是我的代码（主要是CubeIDE生成框架里的用户自定义部分和关键初始化代码）：

注：TIM1的初始化代码是CubeIDE自动生成的，我没做修改，主要配置了上升沿触发的输入捕获。

有没有大佬能帮我看看哪里可能出问题了？比如中断优先级配置？或者输入捕获的模式没设对？
