初学micropython，写个editor练练手： [复制链接]

先来个效果图：

使用方法
putty串口设置：

cmd:
1. import editor
2. editor.edit("sd.cpp")
仅实现了四个方向键，del，ctrl-s保存，ctrl-x退出，支持tab输入
不支持utf8。
虽说内存紧张，打开个几k的文件还是没有压力的。

注意：
数据有价，脚本无情。
没有严格测试...

不错啊，看看了

这个程序是怎么用的？

这个程序是怎么用的？

三个文件复制进去然后

>>> import editor
>>> editor.edit("这里是文件路径")

复制代码

或者

>>> from editor import edit
>>> edit("这里是文件路径")

复制代码

dcexpert

我运行后提示出错了

dcexpert

我搞错了，需要输入一个已经存在的文件，如果文件不存在会报错。
