It seems to me that 0.9.5 sdk is currently being used. To date, I haven't set up my own firmware compiling environment. Is it now recommended, that we set this up and users compile their own firmware to enable/disable features(LUA_NUMBER_INTEGRAL in user_config.h)? I have relied on pre-compiled bins.

I think this is a worthy discussion for the future of prebuilds.

Depending upon the use case and the desire to maximize heap, unless a user can compile their own firmware, the continuation of adding new features breaks current code and further reduces needed heap for other things.

Would it be possible to do pre-builds based on what's enabled or disabled in them? floats, mqtt, node.readvdd33(), etc...? I can't test how taxing these are, but I think it's a good option.

-Thanks!

luckily its quite simple these days:

Code: Select allgit clone https://github.com/pfalcon/esp-open-sdk.git
cd esp-open-sdk
make

add esp-open-sdk/xtensa-lx106-elf/bin to your $PATH

Code: Select allcd ..
git clone https://github.com/nodemcu/nodemcu-firmware.git
cd nodemcu-firmware
make && make flash

so you'd make your changes before that last make.

After installing all the dependencies listed herehttps://github.com/esp8266/esp8266-wiki/wiki/Toolchain and making the path stick in .bashrc.

...all was good. I now have my heap back, can customize and try other things as well

Cheers!
