@ -55,6 +55,22 @@ editing `BIT_RATE_DEFAULT` in `app/include/user_config.h`:
Note that, by default, the firmware runs an auto-baudrate detection algorithm so that typing a few characters at boot time will cause
the firmware to lock onto that baud rate (between 1200 and 230400).
### Integer build
By default a build will be generated supporting floating-point variables.
To reduce memory size an integer build can be created. You can change this
either by uncommenting `LUA_NUMBER_INTEGRAL` in `app/include/user_config.h`:
```c
#define LUA_NUMBER_INTEGRAL
```
OR by overriding this with the `make` command as it's [done during the CI
build](https://github.com/nodemcu/nodemcu-firmware/blob/master/.travis.yml#L30):
```
make EXTRA_CCFLAGS="-DLUA_NUMBER_INTEGRAL ....
```
