Currently in my system we use 16 I/O expanders with I2C interface. I want to change it to CAN interface. Which is the best possible way without compromising the cost? I tried searching for 16I/O expanders with CAN interface but the maximum I could get is 8I/O. Are there any CAN to I2C converters, If yes I can use the same I/O expanders, just put a converter before.
Also looking for ADC with CAN interface!
Please help. Thanks in advance
