Recover from CanBus fault

[ianbenton]

What's the best way to get the CANbus going again after it has stopped?

Example - customer disconnects the CAN cable - CANbus interface detects the fault and stops. What is the best way to restart it without having to restart the program from hardware reset?

Hi, Ian,

I suppose that you use LPC175x, if it is the case, you can reset only the CAN module with the bit CCAN_RST bit, in other words, you can set the bit, then clear the bit, the CAN module  will be reset, then you can reinitialize the CAN module.
