需要做个U盘,最好是符合USB2.0的。并且在主控芯片上还需要集成一些其他功能,因此还需要空余的引脚来编程。顺便推荐一下FLASH吧,做出来的U盘要大于1G。谢谢各位大神指导!

我在这里张贴,寻找一些建议。背景是:这个世界是由白痴和工程师组成的,其中很多;(然后是律师)所以,我们有家庭自动化。全是无线的,因为这是一所旧房子。有了所有的频率,一些DeSt-亚人类选择使用2.4GHz用于ZigBee(和类似的)和WiFi。结果是,当你用你的智能手机下载一些大垃圾(比如谷歌地图离线时,对于我的欧宝来说,没有导航者,多亏了一些白痴,但你会为此付出代价的,我发誓!)家庭自动化死了。我试着在这里和那里争抢频道,但是很明显,WiFi比MiWi/Zigbee使用更多的功率和“频谱”……考虑到我也想在每个房间都有音频…蓝牙是一个很好的选择,但再一次,所有的频率,白痴IEEE和***的白痴工程师使用相同的波段。我真的很好奇Alexa和其他来自谷歌的SeISSE应该如何工作。也许所有的WiFi?家庭自动化,音频,数据……所以把Zigbee扔进垃圾箱。或恢复到900MHz LoRa…以上来自于百度翻译 以下为原文 I am posting this here, looking for some suggestions.Background is: this world is made of idiots and engineers are quite a lot among them ;) (then come lawyers) So, we have home automation. All wireless, since this is an old house. With all frequencies out there, some dement sub-human chose to use 2.4GHz for both ZigBee (and alike) and WiFi. Result is, when you're using your smartphone to download some large crap (such as google maps offline, for my Opel which comes without Navigator, thanks to some more idiots - but you'll pay for that, I swear it!) ......home automation dies. I tried to scramble channels here and there but it's quite clear that WiFi simply uses more power and "spectrum" than MiWi/ZigBee...Consider that I also wanted to have audio in each room... and Bluetooth was a good choice but, again, with all the frequencies out there, the idiots engineers from idiot IEEE and the*** use all the SAME band. I really wonder how Alexa and the other scheisse from google are supposed to work. Maybe all WiFi? home automation, audio, data...maybe. so throw zigbee into the bin. Or revert back to 900MHz LoRa...
