The easiest and cheapest hardware is RPI with SPI can interface ic(there are guides for this).

The other PC that may do that is the Odroid H2+. It has I2c on its GPIO. TI have a reference design for an 12c bridge.

Odroid gets you up to a full PC with Celeron CPU.

That TI example is just running I2C bus over CAN transceivers to get longer range. Not converting CAN to i2c.

Though any SBC or computer with exposed SPI, I2C etc. Communication bus can be used with an approriate protocl IC. It just needs the proper drivers. You can probably use some of the exsisting SPI drivers as a base.

Hi
Long time ago that I was near to can-open. <98.. I judge it would be a monster to write a driver. All the remapping stuff before you see registers that you are interested in.

In earlier days there where coprocessors/drivercards for your pc. Best ones came from Hilscher.
