eCAN interface with TMS320F2802x

Hello,

I have designed board based on TMS320F2802x micro. I know that this series of MCU has no eCAN interface.

Is there any way of using F2802x micro in CAN interface application. For example is it possible CAN interface IC between MCU and connector in the card and outputs of the CAN interface IC can be connected to serial communication (SPI or RX,TX) pins of MCU ?

Regards,

    You're essentially going to be putting down another MCU which has firmware running the CAN to UART/SPI translation....so it may not be too cheap.

    Here is an example

    Also, for a full solution you may want to contact someone like SimmaSoftware.com

    I know they are making an interface dongle from USB to CAN, so it seems like that work would make it simple to create a standalone pre-programmed MCU that did CAN to serial in the other direction. Plus you would get the stack needed for the Piccolo and al the PC side tools.
