关于STM32L476管脚配置的功耗问题
使用STM32Cube 生产代码，测量STM32L476的低功耗，详见 static void MX_GPIO_Init(void) 函数：当把进入低功耗的代码放置在管脚配置之前，测量1.5uA ,正常；当把进入低功耗的代码放置在配置外部中断管脚之后，测量 500 uA
请问是否正常？为什么？
谢谢！

不正常，楼主要根据外部电路进行IO配置。比如外部上拉，就用输入上拉。
感谢回复！图片是相关引脚的原理图，本意是想让按键触发外部中断来唤醒，配置代码是Cube 生成的。
现象是管脚配置成了中断模式后，功耗增加了许多。
不光要考虑中断，其他的引脚也是类似问题。都需要进行对应配置。还有注意悬空的时候，也会有漏电。我一般设置为输出低。
