我正在尝试使用Arduino使用ESP8266制作wifi网络服务器.该代码位于此链接中:代码.我正在关注 此站点的步骤.我已连接yp-01(USB到串行) 与我的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
• TX-> RX
• RX-> TX

我使用的是arduino mega的3.3V电源.

I use the 3.3V supply of my arduino mega.

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

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 失败的错误:espcomm_upload_mem失败

warning: espcomm_sync failed error: espcomm_open failed error: espcomm_upload_mem failed

我读了很多帖子，但是都没有解决我的问题.是否有人知道解决方案或遇到相同的问题?我正在使用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

使用电阻10k将GPIO0和GPIO15接地.

Connect GPIO0 and GPIO15 to Ground with resistors 10k.
