Does anybody know how to enable the eCAN hardware (2803x family) to trigger tranmission of one or more mailboxes from a receive of another?
Preferably without interrupts!
The application is this; CANOpen synchronous PDOs. When a sync pulse is received by a slave, it transmits some of its synchronous PDOs immediately.
I have a heavily loaded processor where the main ISR for motor control is taking >80% of the clock cycles. The CAN routines are run in the background.
It looks like the auto answer or remote frame configuration might be cable of this, but I'm not sure its intended to do this.

Jason
