1.请给出 ESP8266EX 与单片机的连接电路。

2.单片机的串口 TTL 电平是多少？

3.单片机控制 CH_PD（ESP8266EX 使能端）的 GPIO 的电平是多少？

以上请帮忙确认，谢谢！

编译及烧录请参考 \esp_iot_sdk\document 路径下的文档 “2A-ESP8266_IOT_SDK_User_Manual”http://bbs.espressif.com/viewtopic.php?f=5&t=481

请使用最新的 flash download tool v1.2 http://bbs.espressif.com/viewtopic.php?f=5&t=433

如果仍然有问题，麻烦提供您烧录时的烧录工具 flash download tool v1.2 配置截图。

感谢您对 ESP8266 的关注！

另外，我将IOT_DEMO的文件拷贝进APP后，进行编译却无法成功生成bin,请问具体步骤应该是怎么样的呢？我的硬件是ESP-01。
谢谢大家解答，thx.
