Game console design based on Lissang·Liangshan School

 
Thanks to LCSC development board for providing this opportunity to learn GD32 microcontroller and hardware circuit design. Hardware circuit: When designing the board, being a beginner, I was worried about making mistakes, so I reserved interfaces for the buttons and joystick. I did encounter problems during soldering. Because I wanted to save money, I bought a cheap joystick. It wasn't that it was bad, but my skills were too poor; I failed to solder it several times, and the wires even got shorter.
Fortunately, the reserved interfaces came in handy. I originally wanted to implement all the functions of the training camp. I designed the board first and then saw the open-source project, so I had to slowly port it or write my own code. The screen was modified based on the milestones in the component porting process, but the final problem was that compared to others, my screen refresh rate was particularly slow, and there were some display errors.
Then I tried to write a simple Snake game, and encountered the same slow screen refresh problem.
In short, my skills still need improvement, but through this project, I gained a better understanding of the functions of each pin and their applications in circuits. Secondly, when designing the PCB, pay more attention to the reasonable placement of components to make soldering easier, and avoid short circuits and cold solder joints during the soldering process. Through this learning experience, I have gained a better understanding of schematic diagrams, become more proficient in selecting various components, greatly improved my soldering skills, and significantly enhanced my understanding of code. Finally, I am very grateful to LCSC development boards and wish LCSC all the best.
