L’objectif<\/h2>\n

A chaque fois que je devais lire des donn\u00e9es sur la liaison s\u00e9rie, cela \u00e9tait source d’erreurs, de confusions. Bref, \u00e0 chaque fois, du temps perdu et des difficult\u00e9s pour bien traiter le message re\u00e7u.<\/p>\n

Comme je n’ai pas trouv\u00e9 la biblioth\u00e8que que je voulais, je l’ai donc cr\u00e9\u00e9.<\/p>\n

L’objectif est de r\u00e9cup\u00e9rer et de traiter des messages comme les exemples suivantes :
\n– \u00ab\u00a0Help\u00a0\u00bb
\n– \u00ab\u00a0d\u00a0\u00bb
\n– \u00ab\u00a0Red 255\u00a0\u00bb<\/p>\n

La partie avant un \u00e9ventuel espace sera le mot cl\u00e9. La deuxi\u00e8me partie, si elle existe, sera converti en un entier.<\/p>\n

La classe StringSerial<\/h2>\n
\/\/-------------------------------------------------\n\/\/ Classe SerialString\n\/\/-------------------------------------------------        \nclass SerialString\n{\n    public:\n        SerialString();\n        void renew();\n        String get();\n        boolean empty();\n        boolean equals(String str);\n        boolean withParameter();\n        int parameter();\n        boolean isSensoduino();\n    private:\n        String _message; \/\/the whole message\n        String _keyword; \/\/ the first part (before ' ')\n};\n\n<\/pre>\n
La cha\u00eene _message contient tout le message entr\u00e9 en minuscules.<\/p>\n
La cha\u00eene _keyword contient le mot cl\u00e9, la premi\u00e8re partie du message, celle avant un \u00e9ventuel espace (en minuscules).<\/p>\n
En d\u00e9but de programme<\/h2>\n
\/\/------------------------------------------------------------\n\/\/ Librairies\n\/\/------------------------------------------------------------\n\n\/\/ pour le traitement du message recu sur la liaison serie\n#include <SerialDLF.h>\n\n\/\/------------------------------------------------------------\n\/\/ Constantes\n\/\/------------------------------------------------------------\n\n\/\/ Classe de SerialDLF\nSerialString messageRecu;\n<\/pre>\n
La boucle principale<\/h2>\n
\/\/------------------------------------------------------------\n\/\/ Loop\n\/\/------------------------------------------------------------\n\nvoid loop()\n{ \n  messageRecu.renew();  \/\/ on lit un eventuel message.\n  if (messageRecu.empty()==false) \/\/ Si le message est non vide ...\n  {\n    Serial.println(messageRecu.get());\n    traitement();\n    Serial.flush();\n  }\n} \/\/fin loop<\/pre>\n

\n<\/em>
\n<\/em><\/p>\n
Les m\u00e9thodes<\/h2>\n
– renew()<\/strong> : met \u00e0 jour l’instance en lisant les donn\u00e9es sur la liaison s\u00e9rie.
\n– get()<\/strong> : renvoiele mot cl\u00e9.
\n– empty()<\/strong> : teste si le message est vide.
\n– equals(String str)<\/strong> : teste si le mot cl\u00e9 est \u00e9gale \u00e0 la cha\u00eene str, sans tenir comte de la classe.
\n– withParameter()<\/strong> : teste si le message initial contient un param\u00e8tre.
\n– parameter()<\/strong> : renvoie le param\u00e8tre entier.<\/p>\n
Des exemples complets d’utilisation<\/h2>\n
– Mesure de temp\u00e9rature avec le capteur LM35<\/a>
\n– Mesure de temp\u00e9rature, pression et altitude avec le capteur BMP085<\/a>
\n– Contr\u00f4le d\u2019une led RGB<\/a><\/p>\n
