'''Commands and examples – verify before use:''' <br />
<syntaxhighlight lang="text"><br />
sudo apt-get install p7zip-full<br />

sudo wget https://files.waveshare.com/upload/4/4a/Temperature-Humidity-Sensor-code.7z<br />

<br />
== Notes and version constraints ==<br />
* The STM32 examples are based on the STM32F103RBT6 and STM32H743; other STM32 boards require adjusting the hardware connection and porting the code.<br />
* The Arduino example is written specifically for the Arduino UNO; other boards may need modified connections.<br />
* Thonny must be up to date (v3.3.3 under Windows), as older versions lack Pico support.<br />
* The Pico SDK path may differ from the default; the export command must be adjusted accordingly.<br />
* The commands listed assume the specific directory structure and firmware described in the source; deviations require manual verification.<br />
