 - Custom LWIP: (default: ON) By default we are using custom compiled LWIP stack instead of the binary one provided from Espressif. This is increasing the free memory and decreasing the space on the flash. All espconn_* functions are turned off by default. If your application requires the use of some of the espconn_* functions then add the ENABLE_ESPCONN=1 directive. See `Makefile-user.mk` from the [Basic_SmartConfig](https://github.com/SmingHub/Sming/blob/develop/samples/Basic_SmartConfig/Makefile-user.mk#L41) application for examples. If you would like to use the binary LWIP then you should turn off the custom LWIP compilation by providing `ENABLE_CUSTOM_LWIP=0`.
 - SSL: (default: OFF) The SSL support is not built-in by default to conserve resources. If you want to enable it then take a look at the [Readme](https://github.com/SmingHub/Sming/blob/develop/samples/Basic_Ssl/README.md) in the Basic_Ssl samples.
-- Custom PWM: (default: OFF) If you want to use the [open PWM implementation](https://github.com/StefanBruens/ESP8266_new_pwm) then compile your application with `ENABLE_CUSTOM_PWM=1`. There is no need to recompile the Sming library.
+- Custom PWM: (default: ON) If you don't want to use the [open PWM implementation](https://github.com/StefanBruens/ESP8266_new_pwm) then compile your application with `ENABLE_CUSTOM_PWM=0`. There is no need to recompile the Sming library.
 - Custom serial baud rate: (default: OFF) The default serial baud rate is 115200. If you want to change it to a higher baud rate you can recompile Sming and your application changing the `COM_SPEED_SERIAL` directive. For example `COM_SPEED_SERIAL=921600`.
 - Custom heap allocation: (default: OFF) If your application is experiencing heap fragmentation then you can try the [umm_malloc](https://github.com/rhempel/umm_malloc) heap allocation. To enable it compile Sming with `ENABLE_CUSTOM_HEAP=1`. In order to use it in your sample/application make sure to compile the sample with `ENABLE_CUSTOM_HEAP=1`. **Do not enable custom heap allocation and -mforce-l32 compiler flag together**.
 - Debug information log level and format: There are four debug levels: debug=3, info=2, warn=1, error=0. Using `DEBUG_VERBOSE_LEVEL` you can set the desired level (0-3). For example `DEBUG_VERBOSE_LEVEL=2` will show only info messages and above. Another make directive is `DEBUG_PRINT_FILENAME_AND_LINE=1` which enables printing the filename and line number of every debug line. This will require extra space on flash. Note: you can compile the Sming library with a set of debug directives and your project with another settings, this way you can control debugging sepparately for sming and your application code.
 - Debug information for custom LWIP: If you use custom LWIP (see above) some debug information will be printed for critical errors and situations. You can enable debug information printing altogether using `ENABLE_LWIPDEBUG=1`. To increase debugging for certain areas you can modify debug options in `third-party/esp-open-lwip/include/lwipopts.h`.
-- CommandExecutor feature: This feature enables execution of certain commands by registering token handlers for text received via serial, websocket or telnet connection. If this feature is not used additional RAM/Flash can be obtained by setting `ENABLE_CMD_EXECUTOR=0`. This will save ~1KB RAM and ~3KB of flash memory.
