我下载了最新版本的X-CUBE-MCSDK ver。 5.03。发行说明在此版本的受支持控制板列表中显示NUCLEO-F446RE板，但Motor Profiler未显示此板。出现差异的原因是什么？这个董事会很快就会推出新版本吗？或STM网站上的可下载版本不是最新版本？ #x-cube-mcsdk＃nucleo-f446re以上来自于谷歌翻译以下为原文 I downloaded the latest release X-CUBE-MCSDK ver. 5.03 . Release Notes show NUCLEO-F446RE board in the list of the supported control boards in this release but Motor Profiler does not show this board.What is the reasonfor discrepancy? Is this board coming up soon with a new release? Or is the downloadable release on STM site not the latest? #x-cube-mcsdk #nucleo-f446re

`本人最近在做TPMS，FXTH的87的发射功能已经实现。CC1101与CC1101的通信也搞定了。现在想用CC1101接收FXTH87发射的信号，不知是否可以。有没有人做过？关键点在哪里？求指教！`

你好。 我注意到当使用BVLINK或MEMS软件与iPhone配对的设备时，BlueCoin使用大约40-45mA。这似乎很高。基于我过去用于类似用例的其他类似产品，我期待最大10-20mA。此外，如果iPhone应用程序中报告的动力电池电量是准确的（我怀疑自完全充电后它会另外报告97％和80％充电），那么当LiPo容量为20-30％时，设备似乎会关闭。即使设备没有“做任何事情” - 即仅仅与电话配对，该功率使用也是相同的。 因此，我有以下问题： 1）这听起来合理/正确吗？ 2）是否可以关闭所有其他功能以节省电量？ 3）我可以激活超低功耗待机模式吗？我如何唤醒设备？ 4）我可以采取哪些其他节电措施？ 5）充满电后，为什么电池电量在80％到97％之间切换？ 目前我唯一的解决方案是每次要使用麦克风时都要严格关闭设备并重新启动。 具体来说，我的用例是按一个按钮记录一些语音，然后释放按钮停止记录。电池需要至少持续一周。我的空间要求允许LiPo高达500mAh。 我已经阅读了STEVAL-BCNKT01V1 - BlueCoin Starter kit - STMicroelectronics提供的文档，但它们还不够。任何与实际编程BlueCoin更相关的内容都会感激不尽，因为我对这种特殊类型的设备非常陌生（我直到现在才编写Arduinos）。 非常感谢，PartRobot#bvlink＃battery-life #power #bluecoin以上来自于谷歌翻译以下为原文 Hi. I'm noticing that when using the BVLINK or MEMS software with the device paired with an iPhone the BlueCoin is using about 40-45mA. This seems a high. I'm expecting 10-20mA maximum based on other similar products I've used in the past for similar use cases. Additionally, if the power battery levels reported in the iPhone app are accurate (which I doubt since at full charge it reports alternately 97% and 80% charged), then the device appears to shutdown when the LiPo is at 20-30% capacity. This power usage is the same even if the device isn't 'doing anything' - i.e. is merely paired with the phone. Consequently I have the following questions: 1) Does this sound reasonable/correct? 2) Is it possible to shut down all other features to conserve power? 3) Is there an ultra-low power standby mode I can activate? How do I then wake the device? 4) What other power saving measures can I take? 5) Why does the battery level switch between 80% and 97% when fully charged? Currently my only solution is to hard shut down the device and start it up again every time I wish to use the microphones. Specifically my use case is to press a button to record some speech and the release the button to stop recording. The battery needs to last at least a week. My space requirements allow for a LiPo up to 500mAh. I have read the docs available at STEVAL-BCNKT01V1 - BlueCoin Starter kit - STMicroelectronics but they are insufficient. Anything more related to actually programming the BlueCoin would be gratefully received as I'm very new to this particular type of device (I've only programmed Arduinos until now). Many thanks, PartRobot #bvlink #battery-life #power #bluecoin

再有一天重读指令集。记住，有人说微控制器只是I/O和寄存器。看起来好像有MOV指令和流量控制。剩下的是“技巧”或“节省时间”。增量和递减。那样的指示，我想我会同意的。 以上来自于百度翻译 以下为原文Reread instruction set the other day. Keeping in mind someone said microcontrollers are just I/O and registers. Looks like there are MOV instructions and flow control. Then the rest are 'tricks' or 'time savers'. Increment and decrement. That kind of instruction. I think I am going to go with that.
