NodeMCU is an open sourceLuabased firmware for theESP8266 WiFi SOC from Espressifand uses an on-module flash-basedSPIFFSfile system. NodeMCU is implemented in C and is layered on theEspressif NON-OS SDK. The firmware was initially developed as is a companion project to the popular ESP8266-ba...
To useLFS uploadfeature you will have to, except havingluac.corss, build NodeMCU firmware with a special settings for LFS support. You can build it usingNodeMCU custom buildsor other methods. Once you flash LFS-ready firmware to ESP8266, just use--lfsflag foruploadscript, and the CLI will...

关于系统电压读数的问题在ESP8266 github页面#721给出。 根据ESP8266的数据表,TOUT(ESP8266的ADC引脚)引脚在通过ADC测量电源电压时必须悬空(浮动)。但在NodeMCU开发套件/模块上,为了支持外部电压范围(0-3.3V),连接到电阻分压器网络(100Kohm和220Kohm),如下图所示。
