Read your comment after a whole day of desperately troubleshooting an i2c bus on (way too) long wires. I already held an mcp2515 board in my hands thinking about how to retrofit every device with CAN, knowing this would take weeks until robustly running. Maybe adding LTC4311's will keep the system running until I truly have time for the conversion.

Thanks a lot for your comment! (Just created an account to write this!)
