Based on STM32RCT6 microcontroller learning board +417036A

The main control chip uses STM32RCT6. The question requires the design of a learning board, so all the IO ports are led out through pin headers. In order to facilitate the use of the learning board for some small experiments or verification, two types of designs are designed on the board. The screen interface is a 7-wire OLED screen that uses the SPI connection method. At the same time, in order to meet the requirement of displaying color pictures, an interface with an LCD screen is designed. This interface can also be directly connected to the OLED screen. First, Drawing the STM32 minimum system board for the first time, I feel that the early planning was not good, which led to some difficulties in later wiring. I feel that there is still a lot of room for optimization, but since the time is approaching, I can only make sure it can be used in order to complete the assessment. Through this drawing of the smallest system board, I learned how to quickly draw circuit diagrams and make circuit boards on EDA. There is a lot of knowledge in layout and wiring. The same circuit diagram can have many layout formats, but how to make the layout beautiful, practical and practical? It is really a technology and an art. In fact, when I first entered the competition, I really wanted to win the grand prize. Later, I realized that it didn’t matter whether I won the prize or not. It was also good to get coupons for proofing. It’s not that I don’t want to win the prize, but I feel that my project is not worthy! ! !
