【米爾MYD-J1028X開發(fā)板試用體驗(yàn)】開發(fā)環(huán)境體驗(yàn)之python開發(fā)2048小游戲

前言

板子本身安裝了python開發(fā)環(huán)境

使用以下指令查看版本

python --version

root@localhost:~# python --version

Python 3.6.9

配置SSH登錄

電腦和開發(fā)板使用以太網(wǎng)連接。這里使用J5的網(wǎng)口對(duì)應(yīng)eno0.

電腦設(shè)置對(duì)應(yīng)網(wǎng)卡的IP。我這里是192.168.137.1。

串口登錄開發(fā)板

設(shè)置開發(fā)板IP為192.168.137.2.

ifconfig eno0 192.168.137.2

電腦ping開發(fā)板，開發(fā)板ping電腦。

雙向能ping通。如果不能ping通關(guān)閉電腦的防火墻。

vi /etc/ssh/sshd_config

添加一行PermitRootLogin yes

允許ssh root用戶登錄,否則ssh不能以root用戶登錄。

使用crt ssh登錄

輸入密碼root

ftp傳文件

右鍵點(diǎn)擊ssh的窗口,點(diǎn)擊連接SFTP標(biāo)簽頁

lls查看本地目錄

lcd跳轉(zhuǎn)本地目錄

ls查看遠(yuǎn)程開飯啊目錄

cd跳轉(zhuǎn)遠(yuǎn)程開發(fā)板目錄

put 發(fā)送文件到開發(fā)板

get獲取開發(fā)板的文件到本地

binary 二進(jìn)制方式船速和文件推薦使用

Python開發(fā)體驗(yàn) 2048小游戲

將以下2048.py文件導(dǎo)入到開發(fā)板

python 2048.py運(yùn)行

w s a d回車控制上下左右移動(dòng)的方向

總結(jié)

可以看到使用使用python進(jìn)行腳本開發(fā)非常便捷。
