- Tue Dec 13, 2016 11:06 am #59463 I've been hit by a "not enough memory" error when starting a fairly small NodeMCU program, and I've been trying to find out what sort of memory is lacking; there seems to be about 20K of heap space, and about
9K of source code, but I've no idea how much stack space is used (or available).

Has anyone written any memory analysis tools for the ESP8266? They would have to be at the C module level, I guess, and built into the NodeMCU binary, but they would definitely make life easier.

Thanks for any ideas - Will

Please see my Developer FAQ for Q&A on nodeMCU Lua before asking a question here that's already been answered. This and the other official documentation should be your first reference for developing Lua Apps
