Sming (main)

This is the main Sming Component containing all architecture-independent code. All architecture-specific stuff is in either Sming (Esp8266) or Sming (Host).

Configuration variables

Serial Communications

COM_SPEED

Default baud rate for serial port.

This will recompile your application to use the revised baud rate. Note that this will change the default speed used for both flashing and serial comms. See also Esptool and Terminal for further details.

The default rate for serial ports is 115200 baud. You can change it like this:

make COM_SPEED=921600

Debug information log level and format

DEBUG_VERBOSE_LEVEL

When compiled in debug mode (:envvar:SMING_RELEASE undefined) there are four debug levels in increasing level of verbosity:

  • 0: errors

  • 1: warnings

  • 2: information (default)

  • 3: debug

Change it like this:

make DEBUG_VERBOSE_LEVEL=3
DEBUG_PRINT_FILENAME_AND_LINE

Set this to 1 to include the filename and line number in every line of debug output. This will require extra space on flash.

Note

If you change these settings and want them applied to Sming, not just your project, then you’ll need to recompile all components like this:

make components-clean
make DEBUG_VERBOSE_LEVEL=3

Release builds

SMING_RELEASE

By default, this value is undefined to produce a build with debug output. To build for release, do this:

make SMING_RELEASE=1

This remains in force until you change it back:

make SMING_RELEASE=

Localisation

LOCALE

Sming can format dates/time values based on a country code identified by this value. This is provided as a #define symbol for your application to use. See Sming/Core/SmingLocale.h for further details.

Networking

DISABLE_NETWORK

0 (Default) 1 - Remove core networking support

Applications which do not require networking can set this flag to avoid building or linking the core Networking Support library.

This will reduce build times, application size and RAM usage. Builds will not succeeded if network code has been inadvertently included.

DISABLE_WIFI

Note

EXPERIMENTAL

0 (Default) 1 - Exclude WiFi initialisation code

Keeps the core Networking Support library but excludes WiFi code. Applications using ethernet can use this to reduce code size. See Basic Ethernet.
