Problème d'interruptions

[palla]

Je gère plusieurs interruptions :
-Timer Z pour faire un compteur de période variable Tx
-Timer X utilisant l'interruption INT1 pour effectuer la mesure de largeur d'impulsion. Le résultat de cette mesure va déterminer la période variable Tx utilisé dans le timer Z. Je vous joins le programme :

/***********************************************************************************
FILE NAME main.c
DESCRIPTION Main program demonstrating RSKR8C1B peripherals.
This is the main tutorial code. This code will call three functions to
demonstrate Port pin control (FlashLEDs), Interrupt usage (TimerADC) and
C variable initialisation (Statics_Test).
Code to drive an optional LCD module is also included.

Please refer to the tutorial manual for more information on the program flow.

}


}


#pragma INTERRUPT int1_int

void int1_int(void)

{

usWidth.byte.high = tx;
usWidth.byte.low = prex;
h=prex;

Counter = 0xffff - usWidth.word;
tx=0xff;
prex=0xff;

}

Le problème est à mon avis au niveau de l'ordre des interruptions car quelques fois le programme "bug". Qui a déjà eu ce problème et peut m'aider à le résoudre?

Bonjour,

as tu modifier les adresse vecteur dans le fichier sec30.inc

A+
