有关Scratch3连接Arduino的几个问题

4

您好，我想问一下这个repo中的arduino_server.py 和 extension_arduino_nano.py 文件与[extension_arduino.py](https://github.com/CodeLabClub/codelab_adapter_extensions/blob/master/extensions/extension_arduino.py) 的关系是什么？arduino_server.py 和 extension_arduino_nano.py 是能取代extension_arduino.py 在codelab_adapter 中的作用吗？还是需要和extension_arduino.py合作完成通信？（需要同时加入并打开两个插件？） 然后是我在codelab_adapter中打开extension_arduino 插件的时候出现了一个错误： ```text cannot import name 'ui_error' from 'codelab_adapter.utils' (C:\Users\10092\AppData\Local\Temp\_MEI115242\codelab_adapter\utils.pyc) ``` 这是我的codelab_adapter安装或者后来的设置出现了问题吗？还是其他的原因？ 此外，这个和Arduino连接的repo是不是还在完善中，因为当我点击Scratch3中的积木块（eg. led 2 set 1）后，控制台有显示，但codelab_adapter的monitor中没有相关信息。 通过修改codelab_monitor的 extension_eim_monitor.py倒是能通过Scratch3端的eim 拓展的broadcast实现点亮Arduino...

I got what I think are exceptionally high SNRs with the SIONNA UMa channel model when simulating OFDM channels. I am expecting 20 to -3 dB of SNRs across 1000...
