这几天在使用proteus模拟功能学习stm32,在模拟串口时发现proteus中,

1、COMPIM需要直接接单片机的IO口才可以实现和外部虚拟串口通信,即COMPIM是TTL电平的。

2、VIRTUAL TERMINAL虚拟串口显示工具则是RS232电平的,需要MAX232电平转换芯片,将TTL电平转换成232电平才可正常显示。并且VIRTUAL TERMINAL属性中,需要将RX/TX Polarity设置为inverted,否则会显示乱码。

bcac9993 `AutoSuggestBox` has a `SuggestionChosen` event and any reasonable person would assume that this means one of the items was chosen. But with WinUI it's raised whenever a suggestion is merely highlighted. `QuerySubmitted` is the right event instead. Clearly that naming is a lot better than `SuggestionChosen`, since the property to get the chosen item is called `ChosenSuggestion`. WinUI, like the unrelenting wilderness of a world indifferent to human suffering, stands as a testament to the futility of human aspiration.
