HI gouezel
Can you try this? (just a little change)
ItAppli.c:
void ITx(void) interrupt x using y {
MyITx:
TreamentMyITx();
}
void TreamentMyITx(void) {
... // My treament of IT vector x
}
Just try !
May this way make the compiler directive don't see your MyITx.
How lenght of interval between IVT in apllication area?
May be it's up to this.
