华大的HC32L196-qfp64低功耗模式求助，深度休眠电流39.6ua。
1、华大的HC32L196，用的官方的gpio_deepsleep_wakeup例程，把LED功能屏蔽，只留一个按键唤醒，按键是10K上拉电阻到io。2、直流电源直接给单片机供电3.3V，深度休眠电流39.6ua，但是官方例程里面写的是0.6ua，找不出原因。

测试电流的时候注意把SWD下载器断开，否则电流测试不准， 全程不要调试，还是比较准的 yuyu87 发表于 2022-4-18 13:23

下载完我就把swd给拔掉了，我不调试，直接烧进去跑。 redworlf007 发表于 2022-4-18 13:26

这个是LED口，我后面程序把这个屏蔽了，不用，设置为FFFF了 本帖最后由 redworlf007 于 2022-4-18 16:50 编辑
搞定了，淘宝买的开发板，mmp，沙雕把几个io口接到vcc和gnd上了。。。
