Development of NodeMCU

Subsection 3.3: System Command Test

LuaLoader provides many usual NodeMCU system commands. For example, read the left memory capacity "Heap" button; read the ID of ESP8266 chip "chipID" button; software restart command button "Restart", and stop timer "tmr.stop" button, where, by the left click "tmr.stop" can choose the timer number to stop.

If NodeMCU restart, there is error characters. This is because the baud is74880bps, not the default baud 9600bps in the NodeMCU.

"lua:cannot open init.lua" shows that init.lua file cannot be found when the firmware starts. This is because init.lua is used as the application entrance for NodeMCU.
