Hello everybody,

I'm new on this forum, so please forgive if I'm doing it the wrong way...

I'm working on a S7G2 µC (R5FS7G27G3A01CFP), coding with e2-studio, using SSP v1.3.2.

I'm using the CAN bus, and it's working well.

I am coding without the target since few days, so I cannot test the code I generate.

1) I have got a question about the ID of the CAN frames. 

When a mailbox is configured thanks to the SSP, we can choose the mailbox ID, the direction (send or receive) and the frame type.

This configuration can be found in the code generated in the structure : can_mailbox_t

A CAN message has got its own structure : can_frame_t

Those two structures have got a member about the CAN ID called : can_id_t

Question : I want to send CAN frames with different IDs with only one mailbox. Which one of the can_mailbox_t::can_id_t and can_frame_t::can_id_t is the most important ? 

2) I want to use remote frames. Do I have to use 2 mailboxes with the same ID ? (one configured for the reception of the remote frame, and the other configured to send the data frame in response)
