I've successfully ported RTEMS to an in-house 68331-based test
instrument. My gratitude goes out to Joel and and all the others who
have made RTEMS such a nice portable RTOS.
Now it's driver writing time. ;)
The first thing I've decided to tackle is the instrument's internal
(matrix-scanned) keyboard. I currently have polled-mode drivers
working, but the hardware supports interrupts, and I'd like to have the
option of using an event-driven framework.
What are my options for generating events from drivers? Is it wise to
use the rtems_message_queue_* operations from within a device driver or
