怎么查看程序是因为哪个语句进入异常的？&&另外这个HAL 库ADC采样多个通道是不是有问题？
https://pic.imgdb.cn/item/65a50ec8871b83018aff5417.jpg程序卡在这边，但是不知道是哪个语句引起的异常，之前好像看到有一个方法可以查看到进入异常的语句；

目前有三个ADC引脚，每个引脚通过模拟开关进行扩展，想实现就是可以指定ADC对特定的通道进行采样，因为模拟开关要切换（4051），用查询方式就行。
这边有些疑问，ADC是否在每次采样前进行开启？
上面的代码加完之后程序就会跑飞（卡在while(1)里。
1、MDK快速定位硬件异常位置方法，调用show caller code即可快速锁定
https://www.armbbs.cn/forum.php?mod=viewthread&tid=94364
2、代码实现有点问题，配置好后，每次仅需调用HAL_ADC_Start，HAL_ADC_PollForConversion和HAL_ADC_GetValue即可。
