14. 联机五子棋设计与实现¶
14.1. 设计思路¶
- 画出棋盘
- 连接到mqtt服务器
- 时刻检查是否收到消息，监听按键动作，选择落棋位置并判断是否落子
- 接收或发送消息时在屏幕上显示出来，判断胜负
14.2. 代码实现¶
玩家一代码：
导入库文件
import ubitmap
import screen
import time
import text
import network
from machine import UART,Pin
import utime
from umqtt.simple import MQTTClient
import framebuf
定义类并初始化棋盘，默认开始坐标，mqtt服务器信息等
