5.0.0

5.0.0 is our fist major release in the 5 series.

Thanks to our great contributors and special thanks to @mikee47's for his fantastic work.

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.
