bonsoir a tous,
mon projet consiste a réaliser une petite station météo ou le récepteur reçoit la température l'humidité et la valeur de la tension de la lipo
la température/humidité est donnée par un DHT22!
mon problème est au niveau du récepteur!
en effet lors de ma compilation j'ai une erreur :" void value not ignored as it ought to be" sur la ligne de code :
done = radio.read( &meteo, sizeof(meteo) );
(la ligne ce trouve vers la fin du code !
je vous avoue que je sèche sur la question, je ne voie pas ou ce trouve le problème !
merci d'avance pour votre aide.
voici le code du récepteur dans son intégralité:
