CONVERTIR 4 OCTET EN U32

[LUDO_27]

bonjour, je ne comprend la conversion avec la fonction adapter le type qui ne respecte pas le LSB fisrt.

Merci d'avance

De plus pour passer de LSB en MSB y a t il un autre moyen que la conversion en tableau de booléen et l'inversion de celui-ci ?

Reversing the array in the case of little endian is fine, other solution are not really simpler. Here is an alternative.

Ok but for the first idea, it doesn't work with only one byte (if i want to change LSB MSB, i must convert on bit array before).

About ressouce processor what is the best soluce ?

If you only have one byte, byte order is irrelevant. Nothing to do with bits. If you have LSB and MSB, you have at least two bytes.

Please explain.

I trie this morning your example but with 3 bytes (ex an array with 3 data AB CD EF) there is an error. Why ?

If you want to end up with a 4 byte value (e.g. U32), you need a four byte input. If you have less, you need to pad the input to the correct size.
