- Subject: [ECOS] Serial channel sharing the same ISR
Hello,
I would like to know how i can setup x serial channel that share the
same interrupt vector.
My probleme is that my serial channel have to share the same interrupt
vector and I want that the ISR find which channel is interrupting but if
I use SERIAL_CHANNEL_USING_INTERRUPTS with the corresponding
DEVTAB_ENTRY this will overwrite the adresse of the ISR attache to the
vector and the data.
Should I care about it ? Is the " chain all interrupts together" options
the solution to allows for multiple ISR/DSR pairs to be registered for
the same interrupt vector.
Regards,
Nicolas Flaven
