usb2can - USB to CAN & LIN bridge
Freescale proposes an interesting example to start with USB on Coldfire V1 devices: an USB to CAN bridge. This example is built around the MCF51JM128 device and is shown in the application note AN3690. I have used this example to make an USB to CAN & LIN bridge.
At this time, I have only made the board, but the software from Freescale is compatible with my design and can be used, without LIN capability. It's why I only give below the schematic and the PCB layout of this realization.
