1) from machine import Pin 这句话的含义是从machine模块中导入Pin类 2) import time 这句话的含义是导入time 模块 3) led=Pin(4,Pin.OUT) 这句话的含义是在pin #4引脚上创建了一个output的pin 4) led.on() 和led.off() 含义是在该引脚上分别输出1和0 ...
Hard resetting via RTS pin... 我将向你展示的是如何连接到你的电路板上运行的Python提示符。这被称为 REPL,它是 "Read-Eval-Print-Loop "的缩写。这是标准的Python提示符,你可能习惯于在使用常规的Python解释器时看到它,但这次它将在你的电路板上运行,为了与它互动,你将使用串行连接到你的计算机。
