Re: How to use CAN in poll mode?


You could set up an alarm to poll your CAN device.  See the loop back
CAN module for an example.

When I use CAN in Redboot, there is no interrupt enabled. How to drive the

Presently, I add the CAN poll operation in do_idle() by call the CAN driver
DSR periodically.

I don't find there is a standard way to poll CAN module through IO/CAN
APIs, so I have to call driver function directly. Maybe we can add a
CYG_IO_SET_CONFIG_CAN_INPUT_DRAIN config key, to poll CAN module through
ioctl?

Thanks in advance.
