- Tue Dec 30, 2014 7:28 am #5955 I have a problem when compiling nodemcu-firmware on Ubuntu linux:

I have installed toolchain in /opt/Espressif and made the symlinks to xt-xcc etc and get the following error:

- Tue Dec 30, 2014 11:38 am #5970 Hello zeroday,

I have two question about your new firmware version (20141230).
How does the "tmr.time() api" work? Especially the calibration part.
How much RAM is available for LUA programs?
