What is New

It marks the beginning of some very useful and important features that have landed in Sming.
Some of these that might be interesting to you are and are listed below.

Support for RP2040 architecture

Sming 5.0.0 has support for RP2040 architecture. This means that your Sming application can run on a RP2040 board. For that you need to install the RP2040 toolchain using our installation tool. The toolchain is available for both Linux and Windows. And on Linux can be installed with the following command:

./Tools/install.sh rp2040

And then you can recompile your favorite application for this architecture using the make flag SMING_SOC=rp2040. For example the Basic_Blink app can be compiled with the following commands:

cd $SMING_HOME/../samples/Basic_Blink
make SMING_SOC=rp2040

ESP32 support for ESP-IDF version 4.3, 4.4 and 5.0

ESP-IDF is Espressif's IoT Development Framework for ESP32 development. Upgrading to newer versions of IDF can be painful. Unless you have a Sming application. If you already have developed a Sming application for ESP32 then its upgrading it can be as simple as downloading the new IDF version and recompiling the application with that version. IDF versions are available for both Linux and Windows. On Linux version 5.0 for example can be installed using the command below:

INSTALL_IDF_VER=5.0 ./Tools/install.sh esp32

More details can be found in our documentation.

Breaking Changes

• SystemClock::now() returns time_t instead of DateTime.

If you use Websocket functionality make sure to read the notes below.

• Renamed Websocket related types, classes and methods. We used to have WebSocket and Websocket. From now on only Websocket will be used. Example WebsocketConnection::getActiveWebSockets is now WebsocketConnection::getActiveWebsockets.

This is a minor release containing fixes, new features and coding style rules.

Coding Style Rules

• This is the first version in which we started forcing our coding style rules. The coding style rules are applied to the SmingCore and samples directories and their sub-directories. The coding style rules use clang-format to automate the process. You should format your code changes before submitting a PR. This can be done, after installing the clang-format application, with the command

cd $SMING_HOME
make cs

More information about the coding style and ways to integrate automatic fixes in your Eclipse IDE can be found in our Wiki page.

Features

• Added support for the DFPlayerMini ( #1408 )

Bug fixes and small improvements

• Fix to the SmtpClient default port allocation (#1409).
• Fix to the MqttClient and the allowed schemas in the connection URL (#1410).
• Removed unused or deprecated code. DrivePWM is no longer in the code. Use HardwarePWM instead. (#1423).

Automation

• Added automatic check for coding style rules
• Added automatic generation of chocolatey packages on new release (#1406).
