请教下前辈们SDK的Power Library怎么使用？

l52571314 · 发表于 2020-9-23 11:33:48

RT，直接使用SDK中给的 POWER_EnterDeepPowerDown函数电流在20多ma跳动，使用RTC闹钟定时到了以后也能复位启动，就是这个电流对不上。看了下demo进入低功耗也就直接调用这个函数，所以想请教下前辈们是还需要进行其他什么的操作吗

是不是使用了freertos后，低功耗处理得用freertos的库函数？

可以参考一下测量低功耗电流这篇文章：

前辈你好，我看了下你写的这个基于LPC845的帖子也下了SDK看了下，比对了一下LPC845和LPC54606的demo，我发现在LPC54606的demo中没有DEMO_PreEnterLowPower（）这个函数，也就是说demo里面没讲在进入低功耗之前要手动断掉一些时钟。所以想问下power库中像POWER_EnterPowerDown（）这种函数是没有做自动关闭时钟的处理吗？

前辈你好，我看了下你写的这个基于LPC845的帖子也下了SDK看了下，比对了一下LPC845和LPC54606的demo，我 ...

未必是版本太老了？我下了新版sdk2.7的发现有

#if (defined(FSL_FEATURE_POWERLIB_EXTEND) && FSL_FEATURE_POWERLIB_EXTEND)
DEMO_PreDeepPowerDown();
POWER_EnterDeepPowerDown(APP_EXCLUDE_FROM_DEEPPOWERDOWN,
LOWPOWER_SRAMRETCTRL_RETEN_RAMX2 | LOWPOWER_SRAMRETCTRL_RETEN_RAMX3,
WAKEUP_RTC_LITE_ALARM_WAKEUP, 1);
#else
POWER_EnterDeepPowerDown(APP_EXCLUDE_FROM_DEEPSLEEP);
#endif

复制代码

这个电源库扩展是要怎么做？，我可以按照LPC845的fsl_power文件移到现在LPC54606的工程吗？

[求助] 请教下前辈们SDK的Power Library怎么使用？
