[Lichuang Development Board] Liangshan School Game Console Learning

Overview

## Introduction
1. Written in front: Since I study chemistry and usually have to go to work, this is my first time to participate in Lichuang’s training camp. I thought before It would be difficult for me not to participate, but I still couldn’t resist my inner desire. I finally plucked up the courage to buy a development board and participated in the game console training camp. It turned out that it was indeed difficult. When drawing the schematic diagram, PS I found a package with a 3D model for the joystick. After making the board, I found that the size was completely wrong and could not be installed at all. However, because I still have to work (a 2.4-inch screen was welded and broken), it was heartbreaking. The surface of the board was damaged. (Blistering), especially this month was very busy, and the time for handing in homework was almost here, so I thought I couldn’t give up, so I decided to follow the tutorial and write a gluttonous dog.

2. 3.7V lithium battery charging AND boosting: This is an official copy, there is nothing to say, TP4056 is not Don’t mistake CP4056

3. Motherboard wiring: This suggestion is the same as the official game console, otherwise it is easy to make resource allocation errors, and then you have to fly the wires. For example, I have two buttons that conflict. .

4. See the attachment for the complete program. I followed Guangfang’s tutorial completely. The screen of Greedy Dog would flicker. The teacher said that it could be solved by using BUF area buffering, but this is the first time I have heard of it. I'm really confused about BUF and how to apply for memory and so on. If anyone knows how to do it, please give me some advice.
## Thanks to
Through this difficult study, I have gained the following knowledge:
1. Picture taking
2. Sound playback
3. Chinese character display
4. Interrupt processing
5. Program transplantation
Thanks to Jiali Chuang Our novices have such a good platform. During the entire training camp, we have the guidance of Lichuang staff. We don’t have to worry about not being able to complete the homework, and we can really learn a lot.
I almost forgot to attach the link to the demonstration video:
