Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the simply-static domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.

烧录esp8266注意事项

烧录esp8266注意事项

很多人第一次用USB转串口模块烧录esp8266失败,这里有几个注意事项:

USB转串口模块与esp8266的接线方式如下:

1、RX->TX,2、TX->RX,3、3V3->3V3,4、GND->GND,以上接线需要确认好。

还有就是要特别注意的一点:烧录时IO0需要接地,烧录成功后需要断开IO0与GND的连接。另外固件选择要对,我的模块很便宜,选择是1M flash的,具体可以到micropython.org上下载对应固件,thonny这个软件就可以直接烧录,而不需要下载esptool工具。
