lecture d'un tableau uint8_t avec sscanf
Bonjour
j'ai besoin de convertir une chaine de caractere
Code:
1
2
|
char* buffer = "000102030405060708090A0B0C0D0E0F"; |
en un tableau
Code:
1
2
3
|
uint8_t tab[16] = {0x0, 0x1, 0x2, 0x3, 0x4, 0x5, 0x6, 0x7, 0x8, 0x9,
0xa, 0xb, 0xc, 0xd, 0xe, 0xf} |
J'ai essaye avec sscanf ca a marche mais ca donne les warnings
Code:
1
2

Ya t il un moyen d'eliminer ces warnings ?
A l'execution la conversion se fait normalement mais j'ai une erreur
