我正在尝试使用 Arduino 使用 ESP8266 制作 wifi 网络服务器.代码在此链接中:代码.我正在关注本网站的步骤.我已经连接了我的 yp-01(USB 转串口)用我的 ESP8266.

Hi I'm trying to make a wifi webserver with the ESP8266 using an Arduino. The code is in this link: code. I'm following the steps of this site. I've connected my yp-01 (USB to serial) with my ESP8266.

• USB --> ESP
• 发送 --> 接收
• 接收 --> 发送

我使用 arduino mega 的 3.3V 电源.

I use the 3.3V supply of my arduino mega.

• ARDUINO --> ESP
• 3.3V --> VCC
• 地线 --> 地线.

当我尝试上传代码时出现错误:

When I try to upload the code it gives the error:

警告:espcomm_sync 失败错误:espcomm_open失败错误:espcomm_upload_mem 失败

我读了很多帖子，但没有一个能解决我的问题.有没有人知道解决方案或遇到同样问题的人?我使用的是 ARduino IDE 1.6.9

I've read a lot of posts but none of them fixed my problem. Is there anyone who knows the solution or someone who had the same problem? I'm using ARduino IDE 1.6.9

推荐答案

使用 10k 电阻将 GPIO0 和 GPIO15 接地.

Connect GPIO0 and GPIO15 to Ground with resistors 10k.
