Hello,

I am looking for low-cost CAN bus to RS232 or SPI converter. Do you have any suggestions?

    These seem to be tranceivers. Is there one amongst them that offers conversion to RS232 or SPI?

    Seeed and Sparkfun do CAN-BUS shields which would allow you to go from SPI to  RS-232RS-232 using an Arduino etc

     

    "The MCP2515 is a second generation stand-alone CAN controller. It is pin and function compatible with the MCP2510 and also includes upgraded features like faster throughput, databyte filtering, and support for time-triggered protocols."

    MCP2515 - Interface- Controller Area Network (CAN)

     

    • 18-pin package
    • Simple SPI interface to any MCU
    • One-shot mode ensures message transmission is attempted only once
    • Databyte filtering
    • Start-of-Frame (SOF) output
    • Low-power CMOS Technology

    Here is a low-cost card with CANBUS to SPI implemented:

    I have one of these USB-to-CANBUS .... they work well:

    Hi,

     

    I am basically interested in your CANBUS to SPI board. I am looking for this product, but finally ended up with SPI to CAN only.

    Please let me know, would you be interested in selling this board.
