18962: pkg/lwip: Force loglevel when using log module r=maribu a=yarrick 18999: Paho: Allow building for 8 and 16 bit platforms r=maribu a=OlegHahm ### Contribution description Providing a patch to Paho upstream which uses fixed size integers (int32_t) instead of plain int whenever it is used to represent a size of an object. This patch will allow to build the Paho package for platforms where an integer has a width of less than 32 bit. This patch is also provided as a PR to the upstream version of Paho (https://github.com/eclipse/paho.mqtt.embedded-c/pull/238) but unfortunately the upstream seems to be unmaintained. ### Testing procedure Build for a 8 or 16 bit platform that has enough memory for the example, e.g., https://api.riot-os.org/group__boards__atxmega-a1u-xpro.html: BUILD_IN_DOCKER=1 BOARD=atxmega-a1u-xpro make clean all Without this PR this build will fail, with the patches applied it will succeed. ### Issues/PRs references This PR makes #18997 obsolete and thus reverts the change. 19034: boards/nucleo-l496zg: doc improvement r=maribu a=krzysztof-cabaj ### Contribution description This PR adds to nucleo-l496zg documentation MCU table - similar to those, for example for, Nucleo F103RB, F302R8 or F446RE. ### Testing procedure ``` make doc xdg-open doc/doxygen/html/group__boards__nucleo-l496zg.html ``` ### Issues/PRs references None Co-authored-by: Erik Ekman <eekman@google.com> Co-authored-by: Oleg Hahm <oleg@hobbykeller.org> Co-authored-by: krzysztof-cabaj <kcabaj@gmail.com> |

The friendly Operating System for IoT!
RIOT is a real-time multi-threading operating system that supports a range of devices that are typically found in the Internet of Things (IoT): 8-bit, 16-bit and 32-bit microcontrollers.
RIOT is based on the following design principles: energy-efficiency, real-time capabilities, small memory footprint, modularity, and uniform API access, independent of the underlying hardware (this API offers partial POSIX compliance).
RIOT is developed by an international open source community which is independent of specific vendors (e.g. similarly to the Linux community). RIOT is licensed with LGPLv2.1, a copyleft license which fosters indirect business models around the free open-source software platform provided by RIOT, e.g. it is possible to link closed-source code with the LGPL code.
FEATURES
RIOT provides features including, but not limited to:
- a preemptive, tickless scheduler with priorities
- flexible memory management
- high resolution, long-term timers
- MTD abstraction layer
- File System integration
- support 200+ boards based on AVR, MSP430, ESP8266, ESP32, RISC-V, ARM7 and ARM Cortex-M
- the native port allows to run RIOT as-is on Linux and BSD. Multiple instances of RIOT running on a single machine can also be interconnected via a simple virtual Ethernet bridge or via a simulated IEEE 802.15.4 network (ZEP)
- IPv6
- 6LoWPAN (RFC4944, RFC6282, and RFC6775)
- UDP
- RPL (storing mode, P2P mode)
- CoAP
- OTA updates via SUIT
- MQTT
- USB (device mode)
- Display / Touchscreen support
- CCN-Lite
- LoRaWAN
- UWB
- Bluetooth (BLE) via NimBLE
GETTING RIOT
The most convenient way to get RIOT is to clone it via Git
$ git clone https://github.com/RIOT-OS/RIOT
this will ensure that you get all the newest features and bug fixes with the caveat of an ever changing work environment.
If you prefer things more stable, you can download the source code of one of our quarter annual releases via Github as ZIP file or tarball. You can also checkout a release in a cloned Git repository using
$ git pull --tags
$ git checkout <YYYY.MM>
For more details on our release cycle, check our documentation.
GETTING STARTED
- You want to start the RIOT? Just follow our quickstart guide or try this tutorial. For specific toolchain installation, follow instructions in the getting started page.
- The RIOT API itself can be built from the code using doxygen. The latest version of the documentation is uploaded daily to doc.riot-os.org.
FORUM
Do you have a question, want to discuss a new feature, or just want to present your latest project using RIOT? Come over to our forum and post to your hearts content.
