ESP8266-01 is a powerful module that can meet the needs of any of our IoT projects. Since its release, it has formed a very powerful community and evolved into an easy-to-use, inexpensive and powerful Wi-Fi module. Another popular open source platform is the Arduino Development Board, which has built up a large number of projects around the platform. Combining these two platforms will open the door for many

After many days of QT transplantation, we finally got it out today. Record the learning process, but it makes me sad.
Let's talk about the QT source code package. I was very confused when I first installed QT, And I had X11, embedded, and everywhere. Now I understand that X11 can be installed to develop applications running on a PC, and some QT development tools designer and qvfb will be generated.
