Hi
I have been studying on AT90CAN128 datasheet and sample code as well. I have few questions to ask you regarding message object filter and standard ID.
Assuming that I have three AT90CAN128s and each device has two message objects which will be used to transmit and receive data.
Device 1: (Master)
ID - 0x01 (1st priority) - TX (MOb 0)
ID - 0x02 (2nd priority) - RX (MOb 0)
Device 2: (slave 1)
ID - 0x01 (1st priority) - TX (MOb 0)
ID - 0x02 (2nd priority) - RX (MOb 1)
Device 3: (slave 2)
ID - 0x01 (1st priority) - TX (MOb 0)
ID - 0x02 (2nd priority) - RX (MOb 1)
How can I use to filter message object?
2nd question - What is so special about remote frame?
3rd question - There are 2049 different number for ID and why do we need extension ID? What is so special about it?
