Lire un fichier avec un Shield micro SD en C

@fdufnews Oui c'est ce que je pensais aussi, mais comme @jestiin Appel ça l'IDE d'Arduino et que autant je connais Visual code, dans Platforms IO
Je n'ai jamais utilisé mon Visual Studio pour faire de l'arduino.

Du coup avec les commandes de compilation, on pourrait lui indiquer ce qu'il faut essayer de changer, soit ne pas utiliser GCC mais g++ ou changer une directive de compilation.

En tout cas, je ne vois pas trop comment utiliser le framework Arduino en C pure.

J'ai également retranscrit mon code sous l'IDE Arduino, j'ai exactement les memes erreur que sous PlatformIO.

Erreur de compilation pour la carte Arduino Mega or Mega 2560

terwal · March 17, 2023, 10:02am

Je ne sais pas, si de meilleurs connaisseur que moi, peuvent indiquer si la localisation est normal?

Tu n'a pas la commande de compilation qui s'affiche, je crois me rappeler qu'il faut le préciser dans les préférences pour les avoirs.
Mais je n'en suis pas sûr

fdufnews · March 17, 2023, 11:17am

Je ne comprends pas très bien comment le répertoire de travail est organisé.
En principe dans l'IDE arduino, il y a des librairie dans

.arduino15/packages/arduino/hardware/avr/.... (en principe celles livrées avec l'IDE)
et d'autres (celles ajoutées par l'utilisateur) dans un sous répertoire libraries du répertoire de "travail" (le répertoire où sont rangés les "sketch")

Vu la teneur des messages il doit manquer des include.

jestiin · March 17, 2023, 11:32am

Ces erreur ne proviennent pas de mon projet mais de la librairie elle même. C'est pour ca je n'ai pas compris du pourquoi je n'arrive pas a la faire marcher sur un projet en C contrairement à un projet en C++.

fdufnews · March 17, 2023, 1:08pm

On tourne en rond, une erreur sans le code (complet, pour qu'on puisse le tester) qui cause l'erreur cela conduit à un échange complètement stérile.

J-M-L · March 18, 2023, 6:58am

Un bug dans un include ou un define au dessus de l’import du .h peut emmener le compilateur à reporter des erreurs là où elles ne sont pas.

Dernière demande pour Poster TOUT le code sinon ce fil ne sert à rien.

jestiin · March 21, 2023, 10:33am

Pardon pour le retard.

Voici le code que j'utilise pour écrire dans le fichier test.txt se trouvant dans ma carte SD.

#include <Arduino.h>
#include <SD.h>

void main() {
  // put your main code here, to run repeatedly:
  SD.begin(53);

  File myFile = SD.open("test.txt", FILE_WRITE);

  if (myFile) {
    myFile.write("Hello World");
    myFile.close();
  }
}

et j'ai les mêmes erreurs que je vous ai envoyé précédemment.

J-M-L · March 21, 2023, 5:42pm

si vous utilisez main() votre Arduino ne se configure pas. utilisez setup() et laissez la loop() vide
