CAN ID

Post by Lammert Kappers » Tue Oct 25, 2011 3:58 pm

Hello.

I use a PV750 display together with microcontrollers so it is necessary that I send a lot of information over the CAN-bus.
If I make in a Free Form CAN Message a new message I get automatically a Frame ID, in my case ID 18EA0B00.
If I read the CAN-bus with CAN-king I see the ID 18EA0BF2. This last ID is the correct one to receive the messages in the microcontroller.

Who can explain this to me.

Hello Lammert Kappers,

The last byte of the Frame ID (0xF2) is the source address of the PV750.

When you create a Free Form CAN message you have the option to "Update Device Address on outbound messages". If you you uncheck this box the Frame ID will go out exactly as you entered it in the configuration.
