Hi,
I have managed successfully to make the scx200_acb.c module use either
interrupts or use polling, so that I can ultimately operate the adapter
as a slave.
To achieve this, I need a 'task' that sleeps most of the time, and will
get woken up by my ISR. This task can then do one of two things:
(a) If the adapter is busy as a master, then wake the master
state-machine to continue with the comms, or
(b) If the adapter is idle, invoke the slave state-machine to receive
the data from the bus.
(At the moment the ISR just wakes the master state-machine directly.)
Questions:
(1) How is it best to create/start this 'receiver task'?
Should this be done in i2c-core.c ?
(2) An interpreter proc will have to be called by the slave
state-machine. Presumably my 'client' driver will install this
by means of some call-back. Would one use something like
i2c_register_entry() for that ?
I don't really understand fully how all the i2c-* modules fit together,
so please feel free to tell me if I'm off the track here..
Regards,
Thomas
