1、打开Arduino,选择“首选项”,在“附加开发板管理器网址”中填入http://arduino.esp8266.com/stable/package_esp8266com_index.json,然后点击确定保存这个地址。 2、打开工具->开发板->开发板管理器 3、等待开发板管理器启动完成后,移动到开发板管理器的最下方,可以看到一个esp8266 by esp8266 Community,右下...
原因一: ESP8266 不在 UART boot 请通过 UART0 查看 ESP8266 上电打印: ets Jan 8 2013,rst cause:1, boot mode:(1,n) 1. UART boot 对应 boot mode 第一参数为 1, 此值由 [GPIO15, GPIO0, GPIO2] 决定. 即 GPIO15 和 GPIO0 低电平, GPIO2 高电平.boot mode 第一参数不为 1, 即不在烧...
跟你的基本对应，GPIO是哪个也有写，A0下面的G可能就是GND，你可以拿万用表测一下。至于那个GND下面的...

This device driver for IR remotes formerly worked on ESP8266. It now crashes with no changes to code. The problem is related to hard Pin IRQ's and the following code sample demonstrates it. from machine import Pin from time import sleep ...
Hi, could you implement direction control pin to begin? I have a max485 board installed, but I don't have hardware control of the data direction, I need to add the direction control pin attribute to the begin function, which is mapped to the physical port of the microprocessor. emelianov...
