Today I can finally hand in my homework. I have gone through many hardships along the way. Today I finally succeeded. I am very relieved. I have only used 51 single-chip microcomputers before. This is my first time to contact ARM. Being able to succeed has given me great confidence. I also know the power of domestic MCUs. The difficulties I encountered were all solved by looking up information on the Internet. It can be seen that the service and technical support of domestic ICs are also in place. I started with power-on. I did not encounter as many problems as others. After looking at the schematic diagram, I knew that I could input from CN1 or CN100, and SW1 selected the input source. Connect to CN100, pull out the switch, and the development board will light up. At first, I was still thinking about how to play without a burner. Later, I asked the service staff. It turned out that there was a burning IC on the board, which could be burned directly through the CN100 port. This is much more convenient. This port can be powered and burned. Then, it is the construction of the development platform. After some setbacks, they were finally solved. First of all, I would like to thank some diligent coders on the Internet. They have given me a lot of help. Here, I also contribute to some beginners. You can learn from other people's articles before getting these development boards. Here are some recommended websites: https://bbs.21ic.com/icview-3022128-1-3.html, https://home.eeworld.com.cn/space-uid-326693-2.html. I created a folder first, as shown in the figure below: Then I set up the development platform in KEIL5. The process is still very complicated, but it went smoothly. I will upload some pictures for you to see. Of course, the newly created files are extracted from the data provided by the development board. Finally, here is a picture of the original program.
