Bonjour,
Je créé un fichier log.csv sur une carte SD à l'aide d'un pic18f46J50, et plus précisement du matériel EXPLORER 18 + Pic Dem 18F46J50 PIM + Pic Tail Board SD/MMC Card.
Le fichier est bien créé et lisible. Je voudrais écrire du texte dans les 4 premiere cases de la ligne 1, pour avoir un nom de colonne, et ensuite y mettre des valeurs. Je n'est pas de probleme pour ecrire les valeurs.
Mais la chaine de texte quqi correspond à mon nom de colonne fonctionne pour les deux premieres cases, mais pas dans les deux dernieres, alors que j'utilise les meme fonctions.
J'utilise MCC18 Pro et Mplab v8.63.
Voici ce que je ressort du csv :
_____A____|_____B_____|___C___ |_____D___________|_
1|..1ainG_C1....2ainG_C2...... .......3...........4ainD_C4ain DainD
Voila ce que j'ai quand je regarde en txt:
1ainG_C1;2ainG_C2;3;4ainD_C4ai nDainD
Les 4 noms de colonnes que j'utilise sont :
"1ainG_C1"
"2ainG_C2"
"3ainD_C1"
"4ainD_C2"
Vous pouvez les retrouver dans le code. On constate que les deux premières colonnes ont bien leurs nom, mais les colonnes 3 et 4, c'est du n'importe quoi....
Si vous avez une idée, elle est la bienvenue.
Merci de votre aide.
