笔者这里使用的是QTCreator和Python来实现一个简单的串口上位机的开发的简单过程,使用到Python,之前记录的Qt 使用C++写上位机也记录一篇文章,大家感兴趣的话可以看看。从零开始编写一个上位机(串口助手)QT Creator + C++ 这里我使用Python写上位机主要的原因就是Python强大的数据抓取能力以及数据处理能力...

In order to test the communication, we are going to connect the micro:bit pins to a USB to serial converter, so we can use a computer and some serial software to send data to the board. Naturally, this is a procedure we are going to do for testing since, if our aim was simply to...
