La source des données
Bien sur, c’est à l’ordinateur des fournirs, j’ai un programme que j’utilise qui couvre tout les informations essentiels, les avantages est qu’il est gratuit et que les données sont disponibles rapidement et simplement. Les données sont enregistré dans la base de registre, alors je n’ai besoin que de lire la base du registre pour obtenir mes informations.
Après il faut les communiquer au Raspberry. J’utilise dont un principe simple, un serveur Web. Comme ça les donnés sont disponibles et le Raspberry viendra les chercher de lui-même. Accessoirement, le serveur Web peut fournir des fichiers depuis le dossier pcstats/pc/web/.

Il faut l’exécuter, pour ce faire il y a deux fichiers. Le premier est le script de lancement en « .bat », il permet de lancer l’application, mais vu le code Python et les caprices de Windows, vous aurez une console affiché, pratique par contre pour le debug. Inutile de tenter d’utiliser « pythonw.exe »; le script ne ce lance pas.
Le second fichier est un script en « .vbs », il perme de lancer la console en arrière-plan, bref, elle sera caché.
pcstats/pc/run.bat
python.exe pcstats.py
pcstats/pc/run.vbs
Dim WinScriptHost
Set WinScriptHost = CreateObject("WScript.Shell")
WinScriptHost.Run Chr(34) & "run.bat" & Chr(34), 0
Set WinScriptHost = Nothing
Vous avez alors votre service pour afficher vos informations systèmes.
