Hi all, I am working on vehicle body control system with can-bus as my BE final project. It contains three parts.
1.CAN chip driver 2.CAN-bus protocol stack 3.UI
The problem is that I already have written the CAN chip driver as a character device driver using IO-simulated SPI.
Oops, don't do that.
So with this character driver API open() read() write() ioctl(), I start to wonder where can I put my protocol stack?
Use the in-kernel CAN protocol stack, that is much easier.
Or should rewrite the driver in network device frameworks?
Yes.
thanks,
